Abstract:
1. A method for extracting cerebral ventricular system information from images of one or more cerebral ventricular regions, the method comprising the steps of: 1) defining multiple regions of interest (ROIs) in the images, at least one of the images having multiple ROIs defined within; 2) altering the ROIs based on desired histogram distribution within the ROIs; 3) defining seed points within each ROI; 4) growing images of ventricular regions in 3D space while correcting for leakages into extraventricular space; and 5) connecting the ventricular regions grown; wherein: the steps are executed by a computing apparatus, and the steps of defining multiple ROIs, defining seed points and growing images are applied to one or more images of a left lateral ventricle (VLL), a right lateral ventricle (VLR), a third ventricle (V3), a forth ventricle (V4), an anterior commissure (AC), a posterior commissure (PC), and a midsagittal (MSP); the left lateral ventricle (VLL) having a body (VLL-B) and an inferior (temporal) horn (VLL-I), and the right lateral ventricle (VLR) having a body (VLR-B) and an inferior (temporal) horn (VLR-I), each ROI is defined by a two-dimensional area encompassing a ventricle with surrounding white and grey matter, and at least one of said ROIs corresponding to the fourth ventricle.
