ABSTRACT:
The apparatus reduces scatter in radiation imaging and may be used with a detector of ionizing radiation that is partly unscattered and partly Compton scattered. The detector produces an energy signal representing values of energy of the radiation and produces coordinate position information for the radiation. Data storage means for holding numerical values and means for displaying an image based on the numerical values in the data storage means are also used with the inventive apparatus. The scatter reduction apparatus includes circuitry responsive to the energy signal from the detector for producing first and second signals which indicate whether each value of energy represented by the energy signal at a given time is in a first energy range or in a second energy range less than half as wide as the first energy range and having at least some energies in common with the first energy range. Further included is circuitry responsive to the first and second signals and the coordinate position information for generating numerical values for each coordinate position and storing them in the data storage means, the numerical values being a function of the difference of the number of occurrences of radiation in the first energy range at each coordinate position less a second number proportional to the number of occurrences of radiation in the second energy range at that coordinate position. Other apparatus and methods are also described.
