Abstract

The invention provides a crystal array, a detector, medical detection equipment and a production method of the crystal array. The crystal array comprises multiple crystals arranged in an array, wherein each crystal is provided with a light-in face, a light-out face and a connecting face connected with the light-in face and the light-out face, the connecting face of at least one of every two adjacent crystals comprises a rough face and a smooth face connected with the rough face, and each rough face and the corresponding smooth face are arranged along the length direction of the corresponding crystal. According to the crystal array, the rough faces of the adjacent crystals can guarantee that air exists between the crystals, every two crystals are coupled through the air, the detection region of the crystal array is enlarged, and meanwhile it is guaranteed that a certain space exits between the smooth face of each crystal and the adjacent crystal; and through different crystal surface treatment, the transmission path of photons is improved, the crystals in a position spectrum are easy to distinguish, and the error ratio of position counting is effectively lowered.

Description

technical field [0001] The present application relates to the medical field, in particular to a crystal array, a detector, a medical detection device and a manufacturing method of the crystal array. Background technique [0002] Medical testing equipment, such as positron emission tomography (PET) systems, used to observe metabolic processes in the body by injecting drugs labeled with isotopes that emit positrons, such as isotopes of carbon, fluorine, oxygen, and nitrogen, into the body Or two kinds, these drugs have an annihilation effect in the process of participating in the physiological metabolism of the human body, and generate two gamma rays with an energy of 0.511MeV emitted back to back. After the γ-ray interacts in the scintillator, a large number of photons are released, which are detected by the back-end photodetector. The more photons are detected, the better the performance of the detector will be improved. [0003] In order to accurately locate the incident p...
