Problems solved by technology

Therefore, silicon-based photon counting detectors pose a challenge to thermal management systems Photon counting detectors generate a lot of heat to be transported, for example, by water cooling or advanced air conditioning, which would be expensive
[0011] State-of-the-art thermal management systems are used to maintain a general constant temperature environment for energy-integrating detectors, but not for photon-counting detectors

Embodiment Construction

[0038] Throughout the drawings, the same reference numerals are used for similar or corresponding elements.

[0039] The present embodiment generally relates to a photon counting detector and an X-ray detector system including such a photon counting detector, and particularly relates to a photon counting detector with reduced power consumption.

[0040] Reduction of power consumption for X-ray detectors is known in the art. For example, US Patent No. 8,779,907 discloses a portable, battery-operated digital flat-panel X-ray detector that can be switched into various modes of operation in order to conserve power and extend battery life. In more detail, the digital flat panel x-ray detector can be put into sleep mode by deactivating the components that consume most of the power while the remaining components remain active.

[0041] The process of switching the detector between sleep mode and active mode can be well adapted to prior art digital flat panel X-ray detectors. Howeve...

Abstract

A photon-counting detector comprises a first subset of detector modules and at least one second subset of detector modules. Each detector module has power-consuming circuitry. Power-consuming circuitry of detector modules in the first subset is configured, in an operational mode in which the detector modules are powered on, to consume a first amount of power. Correspondingly, power-consuming circuitry of detector modules in the at least one second subset is configured, in the operational mode, to consume a second amount of power that is lower than the first amount of power.

Description

technical field [0001] The present invention relates generally to photon counting detectors and X-ray detector systems including such photon counting detectors, and more particularly to a photon counting detector with reduced power consumption. Background technique [0002] Modern clinical computed tomography (CT) systems consist of a fan-beam geometry with an X-ray source and a tube facing an arc-shaped detector. Acquisition of a large number of X-ray projections at different angles around the patient is performed by continuously rotating the source and detector through 360 degrees in sub-seconds. Record the attenuated (after the patient's illness) and unattenuated (before the patient's illness) X-ray intensity, so as to reconstruct the 3D spatial distribution of the linear attenuation coefficient in the patient's body, and accurately describe the organs and tissues. [0003] The detector is one of the most important components of a CT system. In modern CT systems, the mo...
