Medical DicomSegmentation
uses AI to generate a 3D model from angiogram images and calculates whether blood flow is restricted in narrowed arteries — without requiring medication or catheter insertion...I was labling the catheters,arteries, blood clots, veins, the inner linings...it looked like an MRI
