PHOTON DETECTION METHOD, DEVICE, APPARATUS AND SYSTEM, AND STORAGE MEDIUM

A photon detection method (400), a device (1000), an apparatus (900) and system, and a storage medium. The method (400) comprises: receiving a first number of energy signals respectively output by a first number of shared readout circuits connected to a sensor array (910) and a second number of energy signals respectively output by a second number of independent readout circuits, wherein the sensor array (910) is evenly divided into at least two sensor regions, the first number is equal to the number of sensors in each sensor region, the first number of shared readout circuits are connected in one-to-one correspondence with all the sensors in each sensor region, and each independent readout circuit is connected to individual sensors in the sensor array (S410); determining the location of a reaction projection of high energy photons on the basis of an energy distribution pattern of the first number of energy signals and the second number of energy signals (S420). The photon detection method (400) achieves a re
