Abstract
Examples of systems and methods for monitoring metabolic activity and detectors for detecting photons are disclosed. The methods can include detection in a front and a rear detector of a photon to determine a Compton cone. This Compton cone may be combined with further Compton cone, or Line of Response calculation to determine an origin of nuclear decay. In examples of the systems and methods, substantially real-time visualization of nuclear decay can be achieved.
Claims20
A detector for detecting photons comprising
- a plurality of detector modules forming a front detector and a rear detector,
- the detector modules comprising a plurality of detector devices, and an interface,
- the detector devices having a substrate extending from a front end to a rear end, and carrying a plurality of pixelated semiconductor detector slabs, and being arranged such that the front end is closer to a source of the photons than the rear end,
- the semiconductor detector slabs being arranged on readout circuits, and the detector devices having an input/output element at or near the rear end of the substrate,
- wherein a front group of one or more of the semiconductor detector slabs arranged close to the front end of the substrate are made from a low Z semiconductor material configured to promote photon scattering and form the front detector,
- wherein a rear group of one or more of the semiconductor detector slabs arranged closer to the rear end of the substrate than the front group are made from a high Z semiconductor material configured to promote photon absorption, and form the rear detector.
