Patent ID: 8437522

Claim:
A method of determining a motion index in scanned data, comprising the steps of: obtaining raw data of an object at least from a first location and a second location using one device from a group of scanners involving CT, PET and SPECT; acquiring a first set of line integrals at the first location based upon a corresponding set of the raw data; acquiring a second set of line integrals at the second location based upon a corresponding set of the raw data; converting the first set of the line integrals and the second set of the line integrals to a derivative of a first plane integral (a first DPI) for a first plane and a derivative of a second plane integral (a second DPI) for a second plane, the first plane and the second plane being identical; and determining a first amount of motion of the object based upon a difference between the first DPI and the second DPI.
