Positron emission tomography time-of-flight list mode reconstruction with detector response function |
摘要 |
A PET system includes an improved image reconstruction algorithm based on an improved modeling of the point-spread function. PET time of flight data is used to obtain a mean emitting point and a time of flight probability function. This information is then used to model the point-spread function. The time of flight probability function and the detector response function are used to define a probability volume for a given line of response, which is then used in the reconstruction of the image.
