Computer vision in healthcare
Computer vision in healthcare is software that reads medical pixels — X-ray, CT, MRI, ultrasound, whole-slide pathology, fundus photos, endoscope video — and returns a mark, a mask, or a score a clinician then uses or ignores. It is not a robot doctor. It does not sign the report. The same job gets sold as […]
Machine learning for medical imaging
Machine learning for medical imaging is software that learns from labeled scans — X-ray, CT, MRI, ultrasound, mammography — and returns a mark, a mask, or a score a clinician then uses or ignores. It is not a robot radiologist. It does not sign the report. The same job gets sold as “machine learning in […]
Medical image processing
Medical image processing is the set of computational steps that turn a raw CT, MRI, PET, or ultrasound into something you can measure or fuse. It is the field, not a product list. The software that runs these steps is image analysis software. Segmentation as its own job is medical image segmentation. Three techniques do […]
Cardiac segments
Cardiac segments are the AHA 17-segment map of the left ventricle: a shared language for wall motion, perfusion, and coronary territory. It is not a chamber mask. It is not a volume or an ejection-fraction number. If you meant label LV / RV / myocardium on cine MRI or CT → heart segmentation. If you […]
Effective lung segments on ct: A Practical Guide
Decoding Lung Segments on CT: Foundational Anatomy Understanding lung segments on CT scans begins with a firm grasp of bronchopulmonary anatomy. Imagine the lungs as an inverted tree: the trachea, the trunk, branches into the right and left main bronchi. These bronchi divide into progressively smaller airways, ultimately reaching the bronchopulmonary segments. These segments, the […]
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. […]
