Integrated modular static CT imaging system and CT imaging method

The invention provides an integrated modular static CT imaging system and method, and the system comprises a control system which comprises a CT host and a scanning controller in communication connection with the CT host; the rack is arranged on the ground; the scanning integrated ring comprises an even number of emission detection modules which are arranged in a circumferential array, and every two emission detection modules which are oppositely arranged in the radial direction of the scanning integrated ring form a group; the cathode end of one emission detection module emits an electron beam to the anode target under the control of the scanning controller, and a part of X-rays generated by the anode target sequentially pass through the window and a detected object and then irradiate a first detection area of the detector of the other emission detection module. The other part of X-rays generated by the anode target irradiate a second detection area of the detector of the emission detection module where the
