API for healthcare
An API for healthcare is a messenger between systems that were never designed to talk. Think of a waiter: one system places an order (a request), the kitchen (another system) prepares it, and the waiter brings the plate back. In a hospital that plate is a problem list, a lab result, a DICOM study pointer, […]
Cross section of skeletal muscle
A cross section of skeletal muscle is the cut that shows the connective-tissue layers, the fibers, and the sarcomeres that actually pull. This page is that anatomy — epimysium / perimysium / endomysium, ACSA vs PCSA, pennation, fiber types. It is not a medical-imaging modality survey. If you meant what a medical cross-section image is […]
VTK Data Format Guide: Mastering Advanced 3D Visualization
Demystifying the VTK Data Format: Core Concepts The Visualization Toolkit (VTK) data format is essential for numerous scientific visualization applications. Grasping its core concepts opens up a powerful toolkit for representing and interacting with complex 3D data. Think of VTK as a universal translator for scientific data, converting information from simulations and experiments into a […]
Rotate a 3D image
Rotate a 3D image, in medical volumes, is two different jobs: reorient so the array matches a named patient frame (LPS / RAS), and resample a rotation so the voxels themselves turn (Euler / affine). It is not a Blender orbit of a product shot. It is not a mesh cut. It is not a […]
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 […]
