Analysis and Applications

R2026b
Analyze segmented images, generate surfaces for medical imaging applications

Analyze preprocessed and segmented images to obtain quantitative information about the health of a patient. Interactively measure distances, point coordinates, and the area and perimeter of regions of interest using the Medical Volume Viewer app. Programmatically, you can perform custom analyses by using functions for image arithmetic and calculating region properties, or perform state-of-the-art Radiomics analysis. Use analyzed images for applications such as research, 3-D printing, and finite element analysis.
