Abstract: The present invention discloses an integral anatomical and functional computed tomography imaging system, which includes an x-ray source, a rotational stand for a sample and an imager. The imager includes an x-ray and a gamma-ray scintillator, an image sensor for detecting photon from the scintillator and a pinhole collimator positioned between the rotational stand and the scintillator. During the anatomical imaging process, the x-ray penetrating through the sample will directly irradiate on the scintillator in x-ray mode. During the functional imaging process, the gamma-ray emitted from the radioisotope-injected sample will penetrate through the pinhole of the pinhole collimator and then irradiate on the scintillator in gamma-ray mode. For both cases, photons are generated by the scintillator and picked up by the image sensor.
