The invention discloses a near-infrared two-region common-diameter off-axis optical-CT bimodal imaging system and method. The system comprises a common-diameter excitation module, a signal separationmodule, an optical signal acquisition module, a CT image acquisition module and a data processing module. According to the invention, near-infrared two-region fluorescence imaging and CT imaging are ingeniously coupled in the same system, a near-infrared two-region imaging technology can break through the penetration depth of an optical signal, early detection of tumors is better achieved, the advantage that CT imaging can provide structural information of organisms to be detected is combined, disturbance errors caused by multi-mode imaging in the time domain and space can be reduced, meanwhile, white light data, fluorescence data and CT projection data are obtained, the experiment difficulty is reduced, and errors occurring in data registration are reduced. 本发明公开了一种近红外二区共径离轴光学-CT双模态成像系统和方法，包括：共径激发模块、信号分离模块、光信号采集模
