Abstract
A radiation diagnostic device according to an aspect of the present invention includes a first detector, a second detector, and processing circuitry. The first detector detects Cherenkov light that is generated when radiation passes. The second detector is disposed to be opposed to the first detector on a side distant from a generation source of the radiation, and detects energy information of the radiation. The processing circuitry specifies Compton scattering events detected by the second detector, and determines an event corresponding to an incident channel among the specified Compton scattering events based on a detection result obtained by the first detector.

- a second detector disposed to be opposed to the first detector on a side distant from a generation source of the radiation and configured to detect energy information of the radiation;
- and
- processing circuitry configured to specify Compton scattering events detected by the second detector , and determine an event corresponding to an incident channel among the specified Compton scattering events based on a detection result obtained by the first detector.
A correction method for a Compton scattering event, comprising:
- specifying Compton scattering events detected by a second detector disposed to be opposed to a first detector on a side distant from a generation source of the radiation and configured to detect energy information of radiation, the first detector being configured to detect Cherenkov light that is generated when the radiation passes;
- and
- determining an event corresponding to an incident channel among the specified Compton scattering events based on a detection result obtained by the first detector.
A non-transitory computer readable medium being a computer program product storing programmed instructions, wherein the instructions, when executed by a computer, cause the computer to perform processing of:
