Medical image reconstruction method and system, electronic equipment and readable storage medium

The invention provides a medical image reconstruction method and system, electronic equipment and a readable storage medium. The method is applied to a photon counting CT device and comprises the steps that scanning data are acquired, and the scanning data comprise first data sets corresponding to a plurality of single energy intervals respectively; storing the scanning data in a preset storage space in the photon counting CT device; constructing first identification information of each first data set, wherein the first identification information is used for positioning the position of the first data set corresponding to the single energy interval in a preset storage space; receiving an image reconstruction instruction, wherein the image reconstruction instruction comprises a target reconstruction mode and target identification information; determining a target energy interval according to the target identification information to obtain target data corresponding to the target energy interval; and performing i
