MR Segmentation to draw marker over the MR Dicom Images I am doing R&amp;D over the MR Segmentation to draw marker over the Heart MR Dicom Images. My Question is that how I can draw a such marker over the dicom image that show in attach/link image. that Region of Interesr ROI read from the tag or its part of Pixel Processing.
Typically research papers handling DICOM standard images would probably extract the ROI using pixel processing methods. However, a lot of medical imaging companies like to implement their own DICOM tags(public/private) to keep track of such information for various purposes.

For example, General Electric keeps the following tag enabled on most MR images:

VerticesOfTheRegion found at (0028,9503), which is according to the DICOM standard, a private tag(odd location tags are private)

In short: Its implausible to tell you,how was the ROI extracted without having access to the DICOM metadata of the image in question.
