  • System for quantification of neovasculature in CT volumes
    Patent number: 9420983
    Abstract: When quantifying neo-vasculature growth measured using a CT scanner (10), a known blood voxel is identified and adjoining voxels are compared thereto by a quantifier (52) to determine whether they are blood voxels, in order to grow a 3D image of the blood vessels. A removable Hounsfield calibration phantom (56) is positioned in a subject support (12) and concurrently scanned with the subject during each scan, and a Hounsfield unit calibrator (54) automatically calibrates acquired CT data to the phantom. A transport system comprising a plurality of movement-arresting locations facilitates cheaply and repeatably locking a CT detector (20), in six degrees of movement, at a plurality of locations in the scanner gantry.
