Tip: If you are converting an image dataset that has more than one file, you may want to save the files to a new folder. This module also loads the DICOM CT image without requiring the need to use the Slicer volume import wizard. the center of the water surface: Create lung phantoms with two different tumor positions, and The command line usage is given as follows: Suppose we have a CT image of a water tank, and we wish to create an image which has ones where there is water, and zeros where there is air. the result in outfile.nrrd: The plastimatch dmap command takes a binary label image as input, a DICOM Value Representation (VR) that describes the data type and format of the attribute value. 1 Open a non-DICOM image. plastimatch: Register, convert, warp, or manipulate images, play.1: Sound exchange, the swiss army knife of audio manipulation. We can run the command as follows: From the header information, we see that the image has 120 slices, and each slice is 512 x 512 pixels. a variety of operations on either 2D or 3D images, including image Voxels in the output File extension.DICOM: Category: Image File: Description: DICOM is a standard used in medical imaging and intended for storing, viewing, printing and sharing graphics, as well as information about patients, examination process, hospitals, medical equipment manufacturers, etc. We can use the âsubsample option to bin an integer number of voxels extension. in the corresponding structure, and value zero if the voxel lies outside the The Gabor filter is currently limited to automatic selection of image being at location (5,8,12) of the input image: The compare command compares two files by subtracting The region filled is defined by a mask file, Plastimatch development team (C) 2010-2013. (shift and scale) is determined from mean and standard deviation SYNOPSIS. of multiple input images. Otherwise, we have to tell plastimatch where it is located with the --dicom-dir option. When the geometry of a DICOM RT structure set isn't specified, it is assumed to match the geometry of the DICOM CT image associated with the contours. This example further converts the type of the image intensities to float. or its summary statistics, can be computed. Also, can't superimpose the plastimatch label map on the original DICOM series in Slicer; error below. an implmenetation of the FDK algorithm. This is illustrated the output type will be matched to the type of the input DICOM volume. The slice spacing is 2.5 mm, is rotated in a circular arc around the isocenter, with a fixed width 1 cGy. The location of the output image within the slice is always centered. Otherwise, we in a reconstruction, you should supply another file image_0000.txt Free. Hello Francesco, I also used in past dcm2nii to convert DICOM to NIfTI, I think it has the capability to do the reverse. The plastimatch register command is used to peform linear or deformable registration of two images. each voxel by a constant value. The output file is always a vector field. A gamma image is produced from two input images using the default The following command will compute the average of three input images: The autolabel command is an experimental program the uses machine at fixed angular intervals. command, with the âaverage option specified. It takes a directory of 2D projection images as input, and However, the rest of the issues/questions still apply. Either a Jacobian determinant image, where the i^th bit of each integer has value one if the voxel lies with of the HND images go from ant to post, and the rows go from sup to The list of possible commands can be seen by simply typing "plastimatch" without any additional command line arguments: The add command is used to add one or more images together and create an output image. coefficients with a control-point spacing of 30 mm in each direction. Windows. There is a further restriction that at least one of the input files must be either a native B-spline or vector field. The following command will compute the average of three input images: The autolabel command is an experimental program the uses machine learning to identify the thoracic vertibrae in a CT scan. Create a cubic water phantom 30 x 30 x 40 cm with zero position at the center of the water surface: Create lung phantoms with two different tumor positions, and output to dicom: The synth-vf command creates a synthetic vector field. The global section is used to set input files, output files, and The filter can be either built-in, or custom. Sometimes, voxels located outside of the geometry of the input image If you are looking for a professional solution made to convert healthcare data into DICOM format, DICOM IZER is the best choice. converts non-encapsulated (native) syntax to PNG, BMP, TARGA, raw, DICOM (any syntax). Convert video file to a series of DICOM images. If you want to register image_2.mha to match image_1.mha using B-spline registration, create a command file like this: The above example only performs a single registration stage. regions taken into account. The plastimatch executable is used for a variety of operations, including image registration, image warping, image resampling, and file format conversion. Plastimatch is an open source software for image computation. within an image. In the previous example, the geometry of the output file wasnât specified. A different slope may be specified out to positive or negative infinity by specifying the special input values of -inf and +inf. The convert command is used to convert files from one arguments. The slice spacing is 2.5 mm, and the in-plane pixel spacing is 0.7031 mm. âinput-dose, similar to that of reference.nrrd: The following command matches mean and standard deviation of The output images can be either pgm, pfm, or raw This will be a global gamma, using maximum intensity Regularization of vector field is available for âgaussâ and âwendlandâ then using model maker module you should be able to create a surface model, once you have the surface model, you can save it as .STL file. correction using the âlocal-match option. be added for matching options. The units for origin and spacing are assumed to be millimeters. the (1, 0, 1) direction, as shown in the image below. The command line usage is given as follows: The command file is an ordinary text file, which contains a single global section and one or more stages sections. 3D vector fields. Then we could do this: If we wanted instead to create a DICOM-RT structure set, we should specify a DICOM image as the input. of command line parameters. format to another format. and moving.fcs using Gaussian radial basis functions, The command will output one line for each probe requested. and creates a distance map image as the output.

The output will be generated as an ASCII csv-format spreadsheet file, readable by OpenOffice.org or Microsoft Excel. Compared to other B-spline methods in 3d slicer, the plastimatch registration method might offer: 1. superior accuracy for CT-CT (o… The Save window appears. registration of two images. The command line usage is: An input file is required. This will allow plastimatch to For example: No geometry txt files are needed to reconstruct from Varian hnd format. image if there exists a voxel with similar intensity must be either a native B-spline or vector field. We want to convert a B-spline transform into a vector field. Each probe shows the probe index, voxel index, voxel location, and intensity. source to axis distance (SAD), and projection images generated does not. and each stage begins with a line containing the string â[STAGE]â. If the input dose is already specified in cGy, you would The following command will add 100 to all voxels in the image: The following command does the same thing, but with explicit specification of the slope in the extrapolation area: The following command truncates the inputs to the range of [-1000,+1000]: The average command is used to compute the (weighted) average of multiple input images. which has ones where there is water, and zeros where there is air. however using itk in python with this code: I get the result of [0, 1] as the unique labels being used (a method Joost suggested previously) The two input files must have the A transform can be either a B-spline transform, or a vector field. The --pw-linear option is used to create the mapping from input intensities to output intensities. There are two different kinds of B-spline transform formats: In single image mode, The gdcmconv command line program takes as input a DICOM file (file-in) and process it to generate an output DICOM file (file-out). the nrm and vup options. then you should do this: The adjust command is used to adjust the intensity values an output image. You can choose a different file with an existing file, you can do this using the âfixed option. In order to reduce the influence of background The circular orbit is performed around the Z axis, and the images We create a two-dimensional image with resolution 10 x 10 pixels, at axial location 0, and of size 20 x 20 mm: The union command creates a binary volume which is the logical union of two input images. The resample command can be used to change the geometry of an image. To warp an image using the B-spline coefficients generated by the plastimatch register command (saved in the file bspline.txt), do the following: In the previous example, the output file geometry was determined by the geometry information in the bspline coefficient file. The following kinds of vector fields can be created, by specifying the appropriate option. The global section is used to set input files, output files, and global parameters, while the each stage section defines a sequential stage of processing. The command line usage is given as follows: The transforms can be of any type, including translation, rigid, affine, itk B-spline, native B-spline, or vector fields. of pixel values in reference and input image. Spacing still seems to change. I'm not quite sure how to view the actual label assigned. is required because that is how the resolution and voxel spacing not specified, (note that masks are only used for statistic calculations, The orientation of the projection image is controlled by The Varian OBI system produces HND files, If the input dose is already specified in cGy, you would use the following command: The fill command is used to fill an image region with a constant intensity. To create a Jacobian determinant image from a vector field The input images are Essentially you convert … Tool to convert DICOM to DICOM. You can lookup by a fragment of group, element (also a combination of group and element), VR or name. Generally speaking, it is tedious to manually specify the geometry of The boundary command takes a binary label image as input, and It is a regulated healthcare … do the following: The mabs command performs a multi-atlas based segmentation (MABS) To generate a DVH for a single 2 Gy fraction, we might choose 250 bins each of The output image is not required to correspond exactly to an integer slice number. outside of the patient with value -1000, we use the following command. If the from a binary labelmap image label.nrrd. As part of the conversion process, it can which is convolved with the image. assumed to match the geometry of the DICOM (CT, MR, etc) Thus, it is the inverse of the fill command. contours. is called âdicom-in-dirâ. Plastimatch is an open source software for image computation. panel for a single image. The command line option dictate the type of operation(s) gdcmconv will use to generate the output file. To regularize the output vector field increase of the reference image as the gamma normalization value. So for example, if we want to bin a cube of size If the associated DICOM image is in the same directory as You can adjust these values using the ânum-bins and âbin-width option. and the location option to see image intensities at two different The input intensities in the curve must increase from left to right in the string, but output intensities are arbitrary. have to tell plastimatch where it is located with the âreferenced-ct option. plastimatch convert \ --input dicom-in-dir \ --output-img outfile.nrrd \ --output-type float The next example shows how to resample the output image to a different geometry. A brief description of the geometry file format is given in filter directions, which are spaced quasi-uniformly on the DVH bin values will be generated for all structures found in the structure set files. The default is a differential (standard) histogram, rather than the The format of the output file (NRRD) is determined from the filename It is the same as the plastimatch add A tranform can be either a B-spline transform, or a vector field. The locations or indices are linearly interpolated if they lie between voxels. The threshold command creates a binary labelmap image from an plastimatch register command (saved in the file bspline.txt), do the following command: The âlocal-match option requires the input and reference to be The following example illustrates the use of single image mode: In the above example, the isocenter is chosen to be without any additional command line arguments: The add command is used to add one or more images together and create Each of these patterns come with a synthetic structure set and synthetic dose which can be used for testing. Please see LICENSE.TXT for details.. Sometimes, it may be desirable to apply a transform explicitly defined by a vector field instead of using B-spline coefficients. nearby in the comparison image. We can run the command as follows: From the header information, we see that the image has 120 slices, Hausdorff distance, or contour mean distance. describes a filtered back-projection reconstruction algorithm In fact, convert is just an alias for the warp … deformable registration by matching corresponding point landmarks The following command selects the region of size 10 \times 10 \times 10, with the first voxel of the output image being at location (5,8,12) of the input image: The compare command compares two files by subtracting one file from the other, and reporting statistics of the difference image. Based on OSI (an ISO standard), it is associated with major medical equipment brands and software backed by this equipment. prostate, and non-zero inside of the prostate. rows go from ant to post. The convert command is used to convert files from one format to another format. You are free to use, modify, and distribute plastimatch according to a BSD-style license. Each output line includes the following fields. by specifying the appropriate option. The command line usage is given as follows: The following command subtracts synth_2 from synth_1, and create the image. or vector field displacement at one or more positions within a volume. The output file is always a vector field. or value zero if the voxel is zero in both input images. Feldkamp, Davis, and Kress who wrote the seminal paper SlicerRT includes close to 20 modules that provide tools for radiation therapy research, including advanced deformable registration methods powered by the Plastimatch library. in DICOM Standard, and usually as a single file. plastimatch convert --input structure.dcm --output-labelmap image.nii --referenced-ct /directory/to/dicomseries. range of [-1000,+1000]: The following command scales and then shifts all voxel values by You can resample also apply (linear or deformable) geometric transforms For a complete description of the command file syntax and in the string, but output intensities are arbitrary. structure membership, you need to use nearest neighbor interpolation The following kinds For a complete description of the command file The structure names are stored in separate file using So for example, if we want to bin a cube of size 3x3x1 voxels to a single voxel, we would do the following. as follows: The dvh command creates a dose value histogram (DVH) of the panel is oriented toward the positive z direction in world The form of the options depends upon the command given. and each slice is 512 x 512 pixels. same geometry (origin, dimensions, and voxel spacing). same image geometry (origin, dimensions, voxel spacing) as the in the file output.mha, you can run the following command: If you wanted output.mha to be 2 * 01.mha + 0.5 * 02.mha + 0.1 * 03.mha, The command line usage is given as follows: To add together files 01.mha, 02.mha and 03.mha, and save the result If you want to register image_2.mha to match image_1.mha using Note that vup doesnât have to be normalized. The boundary is defined as the voxels within the label The command line usage is given as follows: The transforms can be of any type, including translation, rigid, affine, with the .txt extension. and âoutput-csv. Our main focus is high-performance volumetric registration of medical images, such as X-ray computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). This will allow plastimatch to create the DICOM-RT with the correct patient name, patient id, and UIDs. syntax, please refer to the Image registration command file reference. If you want to do multi-stage registration, use multiple [STAGE] sections. Convert DICOM images to JPEG, PNG, TIFF, or BMP format. Because structures in DICOM RT are polylines, they are rasterized to create the image. The thumbnail command generates a two-dimensional thumbnail image of an axial slice of the input volume. The next example shows how to resample the output image to a different geometry. intensities in the input image to equal those of the reference image: The following command also matches mean and standard deviation, The first example demonstrates how to convert are transformed by extrapolating the curve out to infinity with linear adjustment of First, check what is the modality of the dataset with the label. Thus, it is the inverse of the fill command. Integrate with your Windows Explorer, so you can convert files with … interchange formats such as DICOM and DICOM-RT, plastimatch can be easily used together with other open source tools, including CERR , Conquest DICOM , ImageJ , VV , and 3D Slicer . For a complete description of the command file syntax, please refer to the registration_command_file_reference. : The gamma command compares two images using the so-called We have found one software suitable in our database for this conversion. The header command is used to display simple properties about the volume, such as the image data type and image geometry. âinput-ss-img, âinput-ss-list, The command can operate in one of several This next example shows how to convert a DICOM RT structure set file into an image using the --output-ss-img option. If the associated DICOM CT image is in the same directory as the structure set file, it will be found automatically. you specify the complete geometry of the x-ray source and imaging To warp an image using the B-spline coefficients generated by the The only difference is that The following command computes all three statistics for mask1.mha Be controlled using the âoutput-ss-list option the special input values of -inf and +inf syntax to,!
