US Patent Issued to CANON MEDICAL SYSTEMS on Aug. 26 for "Time-walk correction using multiple energy measurements" (Illinois, Connecticut Inventors)

ALEXANDRIA, Va., Aug. 26 -- United States Patent no. 12,399,286, issued on Aug. 26, was assigned to CANON MEDICAL SYSTEMS Corp. (Otawara, Japan).

"Time-walk correction using multiple energy measurements" was invented by Yi Qiang (Vernon Hills, Ill.) and Kent C. Burr (Vernon, Conn.).

According to the abstract* released by the U.S. Patent & Trademark Office: "An apparatus and method are provided to correct for time-walk errors during photon detections (e.g., detecting gamma rays). A time-walk correction is determined using measurements of energy (or charge) that apply different time windows, enabling corrections accounting for variations in the ratio between fast and slow components in the detected pulse. For example, one time window can be...
