Patent number: 10782429Abstract: A method and apparatus are provided for positron emission imaging to calibrate energy measurements of a pixilated gamma-ray detector using energy sharing events between channels of the detector. Due to conservation of energy, when the energy of a single gamma ray shared among multiple channels, the sum of measured energies across the respective channel must equal the original energy of the incident gamma ray. Further, the fractions of the original energy distributed to the respective channels can span the entire range of zero to the original energy. Thus, a single gamma-ray source (e.g., cesium isotope 137) can be used to continuously calibrate the nonlinear energy response of the detector over an entire range of interest.Type: GrantFiled: February 6, 2019Date of Patent: September 22, 2020Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Yi Qiang, Xiaoli Li, Kent C.
