Photon counting detector to generate high-resolution images and high-contrast images, and photon counting and detecting method using the same

摘要

A photon counting detector and a photon counting and detecting method using the same is provided. The photon counting detector includes readout circuits configured to count photons in multi-energy radiation incident to a sensor, the photons being counted with respect to each of a plurality of energy bands of the multi-energy radiation, the readout circuits respectively corresponding to pixels of a region onto which the multi-energy radiation is irradiated, each of the readout circuits being configured to count photons in a predetermined one of the energy bands, at least one of the readout circuits being configured to count photons in at least one of energy bands other than the predetermined one of the energy bands.

1. A photon counting detector, comprising:
a plurality of readout circuits configured to count photons in a first predetermined energy band in multi-energy radiation incident to a sensor, wherein at least one of the readout circuits is configured to receive, from an adjacent readout circuit, comparison results based on a second predetermined energy band in the multi-energy radiation, and to count photons of the second predetermined energy band when the comparison results represent that there are photons in the second predetermined energy band; wherein each of the readout circuits respectively corresponds to a pixel of a region onto which the multi-energy radiation is irradiated.
