Techniques for producing an image of radioactive emissions using a Compton camera and Compton lines

摘要

Techniques for imaging radioactive emission in a target volume include receiving data indicating a set of one or more known emission energies associated with a high energy particle source and determining a Compton line for each emission energy in the set. A Compton camera collects location and deposited energy from an interaction associated with a single source event from a target volume of a subject. For the single source event, an earliest deposited energy, E₁, and first scattering angle, θ₁, and a cone of possible locations for the source event are determined. A particular location for the high energy particle source within the target volume without including the single source event, if E₁ is not within a predetermined interval of the Compton line for at least one of known emission energies. A solution is presented on a FILTER display device.
