BAIJIAN - Material testing agency
The present invention provides a positron emission tomography imaging device、 a coincidence efficiency detection method、 and a normalization method. The coincidence efficiency detection method of positron emission tomography includes: obtaining coincidence data of coincidence events; Count the response line based on the matching data to obtain the counting result; Based on the counting results、 the detection efficiency is obtained. In this configuration、 the detection efficiency corresponding to each response line can be obtained in real-time、 and the normalization method constructed based on this can also perform compensation operations in real-time. Thus、 the PET imaging process in the existing technology is solved due to the influence of existing normalization methods、 which results in a long mapping time and a cumbersome process of obtaining normalization coefficients&Nbsp
