A diagnostic imaging system includes a Compton camera (14) disposed on a gantry (16). The camera (14) includes linear detectors (30a, 30b) for detecting radiation emanating from a subject to be imaged. A data processor (32) collects and processes radiation data in accordance with the detected radiation. Position and energy resolving circuitry (34) determines positions and energy deposited by photons striking the detectors. A cone projection generator (40) generates cone projection data or cone integrals based on the collected data which determine a possible location of a gamma source of the detected radiation. A conversion processor (41) converts the cone projection data into plane projection data. The conversion processor (41) includes a line integral processor (42) which determines line integrals representing the cone projection data and applies a spherical harmonic expansion to the line integrals. A plane integral generator (43) generates plane integrals such as Radon projection planes based on the line integrals. A reconstruction processor (44) reconstructs an image representation of a region of interest from the subject from the plane projection data using filtered back projection.
A method of generating an image representation of a region of interest of a subject by a diagnostic imaging system where the subject is injected with a radiation source, the method comprising:
A diagnostic imaging system for reconstructing an image representation of a subject including a plurality of radiation detectors parallelly disposed to each other for detecting radiation from an examination region, and producing electrical data indicative of coordinate locations and energy values on each of the radiation detectors at which radiation is detected, the radiation detected being scattered by at least one of the radiation detectors at a scattering angle, and a reconstruction processor which reconstructs an image representation, the diagnostic imaging system comprising:
A method of generating an image representation of a region of interest of a subject having radiation emitted therefrom, the radiation being detected by a Compton camera, the method comprising:
