Abstract

The invention provides a dual-mode tomography method, device and system which are applied to dual-mode tomography equipment. The dual-mode tomography equipment comprises SPECT equipment and MR equipment, and the SPECT equipment and the MR equipment are arranged in an electromagnetic shielding space. The method comprises the following steps of performing signal shielding on a probe of the SPECT equipment; collecting SPECT signal data of a user to be detected by the shielded probe; and collecting MR signal data of the user to be detected by the MR equipment, wherein the SPECT signal data and theMR signal data are used for performing dual-mode tomography. By using the dual-mode tomography method, device and system provided by the invention, the problem that conventional SPECT equipment of adetector formed by a photomultiplier cannot normally operate in the work environment of the MR equipment can be solved; during detection, signal data can be collected at the same time for tomography;the quality of the collected signals is improved; and the subsequent tomography effect is improved.

Description

technical field [0001] The invention relates to the technical field of biomedical imaging, in particular to a dual-mode imaging method, device and system. Background technique [0002] SPECT (Single-Photon Emission Computed Tomography, Single-Photon Emission Computed Tomography) is an imaging device for clinical nuclear medicine diagnosis, which can provide functional information at the molecular level, and has high imaging sensitivity, but its resolution is low, making it difficult to accurately describe lesions scope. MRI (Magnetic Resonance Imaging, Magnetic Resonance Imaging) is a kind of tomographic imaging, which can use the magnetic resonance phenomenon to obtain electromagnetic signals from the user to be detected, and perform spatial encoding to reconstruct the image of the user to be detected. It has high resolution and can obtain material A variety of physical characteristic parameters, such as proton density, spin-lattice relaxation time T1, etc. [0003] In th...
