Slicer provides support for the most commonly used subset of DICOM functionality, with the particular features driven by the needs of clinical research: reading and writing data sets from/to disk in DICOM format and network transfer - querying, retrieving, and sending and receiving data sets . The DICOM header values are returned as strings. Support; MathWorks The main function to read and parse DICOM files using pydicom is dcmread. xout = dicomwrite(x,'Test_Image','gray',xinfo); I have tried copying the header to a new variable and editing the new one with out any success. The newest version is SPM8, and we use it often for our fMRI data processing. Reload the page to see its updated state. You can now use 3D Slicer with the MatlabBridge extension to do this in a very convenient way: load the DICOM data in Slicer and launch your Matlab function directly from Slicer. . I tested by just creating a copy of the original dicom file and it works fine, but when attempting to save the edited file it is either not saving all the relevant information or throwing up an error. The released software, checkslice reads the slice order direction from a DICOM file, and the MATLAB script provides an idea of how to check SO from EPI data of multiple projects and studies. Accelerating the pace of engineering and science. This plugin queries the DICOM header to return the value for given criterion. dicominfo returns the information in a MATLAB structure where every field contains a specific piece of DICOM metadata. I wonder if that is potentially creating negative values, and if so if that would be a problem? The table below contains the Data Dictionary from DICOM PS3.6 version 2013c. When .
