Embodiment Construction

[0021] Such as image 3 As shown, the detector packaging unit includes: a left detector unit 110, a right detector unit 120, a wedge-shaped mounting plate 130, a special-shaped positioning pin 140, a cylindrical positioning pin 150, a housing 160, and housing fixing screws 170, etc. Before packaging, the detector unit should have been assembled and tested.

[0022] The wedge-shaped mounting plate 130 includes two isosceles trapezoidal surfaces of the same shape, two isosceles trapezoidal surfaces of the same shape, and a rectangular upper top surface. Arranged on the left and right sides of the wedge-shaped installation plate 130 , the rectangular upper surface is arranged on the upper end of the wedge-shaped installation plate 130 . The front side of the wedge-shaped mounting plate 130 is provided with two positioning pin holes 131 arranged up and down for installing the special-shaped positioning pin 140 and the cylindrical positioning pin 150, and the rear side of the wedg...

Abstract

The invention discloses a positron emission tomography detector module and relates to the technical field of positron emission tomography detectors. The positron emission tomography detector module comprises three to five detector encapsulation units, wherein the detector encapsulation units are formed along an axial array. Each detector encapsulation unit is mainly composed of two detector units and a wedge-shaped installing plate. According to the positron emission tomography detector module, the wedge-shaped installing plate can be used for encapsulating the two detector unit in a left and right arrangement to form a detector encapsulation unit. And then, a locating pin hole can be used for precisely locating an adjacent detector module. After that, bolts can be used for forming the three to five detector encapsulation units along the axial array to form the detector module. When one of the detector units appears problems, the troubled detector encapsulation unit can be just replaced to reduce the replacing numbers of the detector units at the time of maintaining and save the maintaining cost. When a detector system is updated, the corresponding number of the detector encapsulation units can be added according to updating requests.

Description

technical field [0001] The invention relates to the technical field of detectors for positron emission tomography. Background technique [0002] Positron Emission Tomography (PET) is an imaging technique used to examine the physiological metabolic level of the examinee, and it is a functional imaging device. During the examination, radiopharmaceuticals with a short half-life are first injected into the body of the examinee, and more radiopharmaceuticals gather around cells with vigorous metabolism. An annihilation event of the radiopharmaceutical emits gamma rays, which are detected using photodetectors. This gamma ray contains information about where the annihilation event occurred. When enough gamma rays are detected, the location where more radiopharmaceuticals are consumed can be identified, thereby obtaining information about physiological metabolic levels. [0003] The detector is the core device of PET imaging. The detector judges the annihilation position and inte...
