Abstract
The present disclosure provides a gamma ray imaging device and an imaging method, where the imaging device includes a plurality of separate detectors. The plurality of separate detectors are provided at an appropriate spatial position, in an appropriate arrangement manner and are of an appropriate detector material, such that when rays emitted from different positions in an imaging area reach at least one of the plurality of separate detectors, at least one of the thicknesses of the detectors, the materials of the detectors, and the numbers of the detectors though which the rays pass are different, thereby achieving the effect of determining the directions of rays.
Claims20
A gamma ray imaging device, comprising:
- a plurality of separate detectors,
- wherein rays emitted from different positions in an imaging area reach at least one of the plurality of separate detectors through different sets of one or more other detectors of the plurality of separate detectors, and
- wherein the sets of one or more other detector are different in at least one of thickness of detector, material of detector, or number of detectors.
An imaging device, comprising:
- a plurality of separate detectors,
- wherein the plurality of separate detectors form a plurality of detector layers arranged outside an object to be detected, and
- wherein two adjacent detector layers are spaced from each other by an interval.
An imaging device, comprising:
- a plurality of separate detectors,
- wherein the plurality of separate detectors comprise at least two types of detectors,
- wherein the plurality of separate detectors form a plurality of detector layers arranged outside an object to be detected, and
- wherein the imaging device further comprises a collimator located between the object to be detected and a detector layer located innermost along movement direction of photons.
