Problems solved by technology

[0006] The process of injecting radioactive solution into the phantom is manually operated. During the process of injecting radioactive solution, technicians will be close to the radioactive solution for a long time, and the activity of the radioactive solution is relatively high, and the radioactivity is relatively high. The risk of radiation exposure to personnel is likely to cause safety accidents

Abstract

The invention, which belongs to the technical field of the computer, discloses a method and apparatus for determining an ideal single-lifting counting rate. The method comprises: distances between unit regions in a curved surface formed by rotation of a bar source of radioactive activity in a direction parallel to an axial direction of positron emission tomography (PET) equipment at a first distance being a distance to the axis of the PET equipment and all crystals of the PET equipment as well as angles of each unit region and each crystal are determined; and according to the distances between the unit regions and the crystals and the angles of each unit region and each crystal as well as a preset ideal single-lifting counting rate algorithm, a current ideal single-lifting counting rate of each crystal is determined. Therefore, being close to a radioactive solution by a technicist for long time can be avoided and thus the risk of radiation on the technicist can be reduced; and an accident can be prevented.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and a device for determining an ideal single count rate. Background technique [0002] In the field of medicine, PET / CT (positron emission tomography / computed tomography, positron emission tomography / computed tomography) equipment can be used for early diagnosis of human or animal tumors, heart system diseases and nervous system diseases. The detection unit can be arranged in the PET equipment, and the detection unit can include a plurality of detection units, and the detection units are arranged symmetrically in a circle in the cross-sectional direction, wherein, any detection unit can be a crystal (Crystal) or a A crystal matrix composed of multiple crystals, such as a 14×14 crystal matrix, etc. In addition, the detection component may also include a photoelectric conversion device (such as a photomultiplier tube), an electronic circuit board, and the like.
