Abstract

The invention relates to a data detection and acquisition system for a CT machine. The system includes: a semiconductor detector, a photon counting module and a charge integration module, and also includes: a first gate switch, which is located between the anode of the semiconductor detector, the photon counting module and the charge integration module, and is used to connect the anode to the photon counting module. module or connect the anode to the charge integration module.

Description

technical field [0001] The invention relates to a data detection and acquisition system, in particular to a data detection and acquisition system for a CT machine. Background technique [0002] The data detection and acquisition system in a CT (Computer Tomography) machine may include a detector (Detector) and a data acquisition system (Data Acquisition System, DAS). Detectors can be used to detect X-rays and convert them into electrical signals, and DAS can collect and process electrical signals from the detectors. [0003] Existing DASs may contain photon counting modules and / or charge integration modules. The photon counting module can count the photons of the signal output by the detector, and then use it for X-ray energy spectrum imaging. The charge integration module can integrate the signal output by the detector to obtain the total amount of charge, which is then used to generate conventional CT images. [0004] An existing detector uses semiconductor materials (s...
