Abstract

The invention specifically relates to a CT detector framework, which comprises a data acquisition circuit board, a data control board and a plurality of detector modules, the data acquisition circuit board is provided with an MCU and an FPGA, the MCU is in communication connection with the FPGA, and the FPGA is in communication connection with the data control board and all the detector modules; The FPGA is in communication connection with a data acquisition card of the reconstruction computer through a slip ring; the FPGA is provided with read-write registers in one-to-one correspondence with the detector modules, the MCU controls the states of the read-write registers on the FPGA, and the FPGA communicates with the corresponding detector modules according to the states of the read-write registers. According to the invention, data acquisition and information processing are separated, i.e., the FPGA performs data acquisition and the MCU performs information processing; the powerful operational capability of the MCU is used for command analysis, logic operation, state monitoring and low power consumption, and the powerful digital signal processing capability of the FPGA is used for data acquisition, so that the data acquisition and information processing efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of CT, and in particular relates to a CT detector framework, an information processing method thereof, and a CT scanner. Background technique [0002] CT scanners use CT detectors to detect X-rays passing through the human body and convert the received light signals into electrical signals. The CT detector is one of the core components of the CT scanner, which is mainly used to collect the data information after the X-ray passes through the human tissue, and provides the basis for reconstructing the CT image of the human tissue. [0003] When the CT detector is working, it needs to quickly transmit the collected image data. The real-time requirements of image data are high, the frequency is high, and the amount of instantaneous data is large. Therefore, high-speed, high-precision acquisition and high-speed transmission of image data are required. . At the same time, the CT detector also needs to monitor it...
