Abstract
A device and method in which image scanning circuitry acquires imaging information of an object, and thermal detection circuitry is disposed in close proximity to the image scanning circuitry. The thermal detection circuitry estimates a temperature of the image scanning circuitry by calculating a thermal transfer of heat passing from the image scanning circuitry to the thermal detection circuitry.
Claims17
A detection apparatus, comprising:
- a radiation sensor configured to receive radiation emitted from an object to be imaged, and output a detection signal corresponding to the received radiation;
- first processing circuitry arranged adjacent to the radiation sensor and configured to process the detection signal output by the radiation sensor;
- a board on which the first processing circuitry is mounted;
- a thermal probe configured to measure a temperature at a particular location on the first processing circuitry or on the board;
- and
- second processing circuitry configured to estimate a temperature of the radiation sensor based on the measured temperature from the thermal probe.
A method for estimating a temperature of a radiation sensor configured to receive radiation emitted from an object to be imaged and to output a detection signal corresponding to the radiation, the method comprising:
- receiving, from a thermal probe, a measured temperature at a particular location (1) on first processing circuitry arranged adjacent to the radiation sensor and configured to process the detection signal output by the radiation sensor, or (2) on a board on which the first processing circuitry is mounted;
- and
- estimating, by second processing circuitry, the temperature of the radiation sensor based on the measured temperature.
