Abstract

The invention provides a detector module and a medical imaging device. The detector module comprises a scintillation crystal array, a photoelectric detector array and a readout circuit board, wherein the scintillation crystal array is connected with the photoelectric detector array, and the photoelectric detector array outputs a collected signal through the readout circuit board; the detector module further comprises support blocks positioned on the end part of the scintillation crystal array, and a support board positioned between the photoelectric detector array and the readout circuit board, wherein the support blocks are connected through the support board, and the end blocks, namely, the support blocks and the support board define the space for accommodating the scintillation crystal array and the photoelectric detector array. The detector module disclosed by the invention is high in structural strength, and the coupling between a photoelectric detector and scintillation crystal is good.

Description

technical field [0001] The present invention mainly relates to the technical field of medical imaging, in particular to a detector module and a medical imaging device equipped with the detector module. Background technique [0002] In the field of medical imaging technology, according to the principle of imaging, it can be mainly divided into radiological imaging - that is, X-ray computed tomography (XCT, X-ray Computed Tomography), magnetic resonance imaging (MRI, Magnetic Resonance Imaging), ultrasound imaging (USG, Ultrasonography) And radionuclide imaging - including gamma camera, single photon emission tomography (SPECT, Single PhotonEmission Computed Tomography), positron emission tomography (PET, PositronEmission Tomography). [0003] Among them, the core device of positron emission tomography (PET) imaging is the detector. The detector judges the annihilation position and intensity of the radionuclide in the human body according to the detected coincidence events. Th...
