Set TFto false to read these compliant files. When TFis true (the default), a small number of compliant files will not be read correctly. dicomread displays a warning if the heuristic is used. = dicomread(_,'UseVRHeuristic',TF) instructs the parser to use a heuristic to help read certain noncompliant files which switch value representation (VR) modes incorrectly. v must be an integer scalar, a vector of integers, or the string 'all'. = dicomread(filename, 'frames', v) reads only the frames in the vector vfrom the image. If no overlays are in the file, overlays is empty. If multiple overlays are present in the file, overlays is a 4-D multiframe image.
Each overlay is a 1-bit black and white image with the same height and width as X. = dicomread(.) returns the image X, the colormap map, an alpha channel matrix for X, and any overlays from the DICOM file. alpha has the same height and width as X and is 4-D for a multiframe image. The RGB value in map should be substituted for the value in X to use alpha. The values of alpha are 0 if the pixel is opaque otherwise they are row indices into map. = dicomread(.) returns the image X, the colormap map, and an alpha channel matrix for X. If X is a grayscale or true-color image, map is empty. = dicomread(.) returns the image X and the colormap map. This applies to both single-patient and batch feature extraction.= dicomread(_,'UseVRHeuristic',TF) Description If one would like to extract features of parotid glands only, it can be achieved by changing 'all' to 'parotids' in the selection menu below the patient name. 'tps_data.mat' files can be easily calculated for all patients by doing batch DICOM import explained in the previous paragraph.īy default, features of all rt structures are extracted. There is no need to manualy load 'tps_data.mat' files but they need to be present in patient directories. Requirements for patient directory structure are the same as for batch DICOM import. To do this, one needs to select 'Batch' checkbox and then click on 'Calculate features' button. To extract features of a single patient, one needs to load the patient's 'tps_data.mat' file by clicking on 'Load '*.mat'' button and then click 'Calculate features' button.įeatures can be also extracted for multiple patients in one go. For example: 'input_directory/patient1', 'input_directory/patient2' and so on. The patient files need to be organized in such a way that each patient files are stored in a separate subdirectory of the input directory.
In order to import DICOM files of more than one patient at a time, one can do batch DICOM import by selecing 'Batch' checkbox and then clicking on 'Import DICOM' button. After successful DICOM import, 'tps_data.mat' file is created in the directory containing the patient's files. To import DICOMs of a single patient, click on 'Import DICOM' button and specify the import parameters. Move to DicomToolboxMatlab directory and start the GUI by executing 'start.m'. DicomToolboxMatalb allows to import, visualize, and extract image features from CT and RT Dose DICOM files in MATLAB.
