Abstract
Embodiments of the present disclosure provides a photon counting detector. The photon counting detector may include a crystal including a crystal cathode, a support, a conductive layer electrically connected to the crystal cathode, and a compression structure that is connected to the support and presses one side of the conductive layer on at least a portion of a surface of the crystal cathode.
Claims20
A photon counting detector, comprising:
- a crystal including a crystal cathode;
- a support;
- a conductive layer electrically connected to the crystal cathode;
- and
- a compression structure that is connected to the support and presses one side of the conductive layer on at least a portion of a surface of the crystal cathode.
A photon counting detector, comprising:
- a crystal including a crystal cathode;
- a conductive layer electrically connected to the crystal cathode;
- and
- a compression structure that compresses one side of the conductive layer on at least a portion of a surface of the crystal cathode, so that the conductive layer is able to deform under a pressure of the compression structure and connect to the crystal cathode.
A medical imaging device, comprising a photon counting detector and a high voltage power supply device, the photon counting detector including:
- a crystal including a crystal cathode;
- a support;
- a conductive layer electrically connected to the crystal cathode;
- and
- a compression structure that is connected to the support and presses the other side of the conductive layer on at least a portion of a surface of the crystal cathode;
- wherein the conductive layer of the photon counting detector is electrically connected to a high voltage negative electrode of the high voltage power supply device.
