Heart segmentation

Heart segmentation is labeling the chambers and walls of the heart on medical images so you can measure volume, ejection fraction, wall thickness, and scar — not just watch a beating blob. The usual input is short-axis cine MRI. CT and echo show up too. The output is a mask of the left ventricle (LV), […]

Liver segments on CT

Liver segments on CT are the eight Couinaud units — each with its own portal inflow, hepatic-vein outflow, and bile duct. This page is that map on a contrast CT. It is not an organ-mask how-to, and it is not ultrasound. If you meant the liver organ mask (automated contouring) → liver segmentation on CT. […]

Liver segmentation on CT

Liver segmentation on CT means drawing the organ’s boundary — a mask of the liver, not the eight Couinaud segments inside it. Manual contouring on every slice is slow and operator-dependent. Automated methods (thresholding, region growing, CNNs) do that contour so a volume, a radiation plan, or a resection remnant has a number attached to […]

CT scan to 3D model

Going from a CT series to a model you can rotate, measure, or print is a conversion job. You isolate anatomy, build a mesh, clean it, and export a format the next tool accepts. This is not the same as reconstructing slices from projections. That already happened on the scanner. In the mid-1980s, stacking 50–60 […]
