  • Data processing of group imaging studies
    Patent number: 9177103
    Abstract: A system for processing multi-subject volumes comprises a volume input (1) for receiving an input volume image dataset (13) comprising a plurality of subjects scanned simultaneously. A metadata input (2) receives metadata (15) relating to individual ones of the subjects. A subject finder (3) identifies a plurality of portions of the input volume image dataset (13), each portion comprising one of the subjects. A volume image dataset generator (4) generates a plurality of separate volume image datasets (16), each separate volume image dataset (7) comprising one of the portions of the input volume image dataset. A metadata handler (5) associates the metadata (15) relating to a subject with the separate volume image dataset (7) comprising the portion comprising the subject.

  • Visualization and quantization of newly formed vasculature
    Patent number: 8417319
    Abstract: An angiographic image processing system includes a filtering module (40) configured to filter an angiographic image based on blood vessel diameter (46) to identify neovasculature having small blood vessel diameter, and a display sub-system (32, 70) configured to display the angiographic image with the identified neovasculature. A neovasculature density computation module (72) is configured to compute density of the neovasculature identified by the filtering module (40).
