Module Description

The OpenCAD is designed to segment tumors from DCE-MRI datasets which include 1 pre-contrast image and 2-4 post-contrast images at different time points. OpenCAD uses blackbox methods to calculate the wash-in and wash-out slopes of the contrast dye based on voxel intensity values. The segmentation output is a Label Map with red, yellow, and blue colors respectively identifying washout, plateau, and persistent voxels.
