AI Technical Summary
Existing PET imaging equipment has shortcomings in terms of reaction depth decoding capability and decoding accuracy. Software correction schemes are computationally expensive and lack stability, while hardware correction schemes are complex in structure and suffer from severe photon loss.
By employing a shared optical crystal module, a light-transmitting window is opened on the scintillation crystal array to guide the distribution of visible photon groups on the photoelectric sensor. The position and depth decoding of high-energy photons are achieved by utilizing the signal strength relationship of the photoelectric sensor array.
It improves the spatial resolution and sensitivity of imaging equipment, simplifies the structure, reduces the number of photoelectric sensors and system complexity, and enhances decoding accuracy and system sensitivity.
