A multi-mode imaging system, comprising a display (100), a multi-mode imaging device (200), and a host (300) electrically connected between the display (100) and the multi-mode imaging device (200). The host (300) is internally provided with an image reconstruction and processing subsystem. The multi-mode imaging device (200) is internally provided with an animal scanning control subsystem (201), a static computed tomography subsystem (220), and a photoacoustic imaging subsystem (230). The static computed tomography subsystem (220) comprises an electronic control circuit (221), a multi-beam carbon nano X-ray source array (222) used for generating X-rays (500) required by static computed tomography scanning, a photon counting detector (223) used for computed tomography projection data collection and high-speed processing, and a power supply (224) used for supplying power to the multi-beam carbon nano X-ray source array (222). The multi-beam carbon nano X-ray source array (222), the photon counting detector (223), and the power supply (224) are electrically connected to the electronic control circuit (221). The multi-mode imaging system is high in image resolution, large in imaging depth and low in radiation dosage.
