Abstract

The invention provides an SPECT and PET dual-mode imaging system and an imaging method thereof and relates to the technical field of medical imaging. The system comprises a work mode setting unit, a detector and an image reconstruction unit, wherein the work mode setting unit is used for setting the work mode of the SPECT and PET dual-mode imaging system; the work mode comprises an SPECT single-mode imaging mode, a PET single-mode imaging mode and an SPECT / PET dual-mode imaging mode; the detector is used for collecting corresponding gamma rays according to the work mode and storing the gamma rays as SPECT / PET imaging data according to energy size of the gamma rays; the image reconstruction unit is used for processing the SPECT / PET imaging data so as to obtain SPECT / PET reconstruction images. The SPECT / PET imaging can share one detector, so that the radiation dose of the SPECT and PET dual-mode imaging system to human bodies is reduced, and the SPECT and PET dual-mode imaging system is small in size, low in cost and convenient to movement and adjustment.

Description

technical field [0001] The invention belongs to the technical field of medical imaging, and in particular relates to a SPECT (Single PhotoEmission Computed Tomography, single photon emission computed tomography) and PET (Positron Emission Tomography, positron emission tomography) dual-mode imaging system and an imaging method thereof. Background technique [0002] Medical imaging technology is divided into two categories: structural imaging technology and functional imaging technology. Common structural imaging techniques include CT (Computed Tomography, computer X-ray tomography), MRI (Magnetic Resonance Imaging, magnetic resonance imaging) and ultrasound imaging, while functional imaging techniques include optical and nuclear medicine functional imaging lamps. Nuclear medicine functional imaging is divided into two imaging techniques: PET and SPECT according to different radioactive tracers in the body. The former uses positron radioactive tracers labeled with positron nuc...
