Patent ID: 8724872

Claim:
An imaging system comprising: a first source of radiation configured to direct first radiation towards an object by moving in a predetermined path along a first set of targets, the first set of targets including: (i) multiple emission targets placed at different positions and configured to emit first radiation in response to being irradiated with the first source, and (ii) multiple blank targets placed at different positions and configured to suppress the emission of the first radiation in response to being irradiated with the first source; a second source of radiation configured to direct second radiation towards the object concurrently with the first radiation by moving in a predetermined path along a second set of targets, the second set of targets including: (i) multiple emission targets placed at different positions and configured to emit second radiation in response to being irradiated with the second source, and (ii) multiple blank targets placed at different positions and configured to suppress the emission of the second radiation in response to being irradiated with the second source; a detector configured to detect the first radiation and the second radiation and to create sets of data, each set of data comprising a representation of a detected combined radiation of a combination of the first radiation emitted at a particular target of the first track with the second radiation emitted at a particular target of the second track; a processor; and an electronic storage coupled to the processor, the electronic storage including instructions that, when executed, cause the processor to: receive the sets of data from the detector, and determine, from the sets of data, a representation of the radiation emitted from a particular target of the first set of targets based on the representations of detected combined radiation and the placement of at least one of the blank targets in at least one of the predetermined paths.
