Problems solved by technology

[0007] At present, medical institutions in my country generally use independent PET equipment and MRI equipment. When it is necessary to obtain the results of combined diagnosis of PET / MRI image fusion, it is necessary to perform PET detection and MRI detection respectively, and then perform PET detection images and MRI detection images. Fusion processing, the detection method is relatively cumbersome, which also affects the accuracy of diagnostic results

Embodiment Construction

[0032] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0033] Embodiment 1 of the present invention provides a combined diagnostic device that integrates PET-MRI functions, combines PET molecular imaging with MRI soft tissue contrast functional imaging, and can image disease cells spreading in soft tissue, enabling patients to Scan in various modes; PET and MRI images can be collected separately.

[0034] Embodiment 2 of the present invention is an intraoperative MRI demonstration. The PET equipment is removed, and the distance between the two superconducting coils of the MRI is increased, wherein the two superconducting coils constituting the MRI are connected by a liquid helium filling body; There is an operating space that enters vertically, and the medical staff can directly enter and ...

Abstract

The invention provides combined diagnosis equipment integrating a PET-MRI (positron emission tomography-magnetic resonance imaging) function and belongs to the field of medical instruments. The combined diagnosis equipment comprises a guide rail, an MRI device and a cylindrical PET imaging device, the MRI device is arranged on the guide rail and used for acquiring images of a patient, the cylindrical PET imaging device is used for acquiring images of the patient, and central line of an imaging hole of the MRI device is coincident with central hole of an imaging hole of the cylindrical PET imaging device. The combined diagnosis equipment combines molecular imaging of PET and soft tissue comparison function imaging, so that disease cells diffused in soft tissue can be imaged, the patient can scan the disease cells in various mode, and PET and MRI images can be collected respectively.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a combined diagnostic device integrating PET-MRI functions. Background technique [0002] Positron Emission Tomography (PET) uses drugs such as glucose, amino acids, choline, thymine, receptor ligands, and blood flow imaging agents labeled with positron emitters as tracers. Anatomical images display the metabolism, function, blood flow, cell proliferation or receptor distribution of the body and lesion tissue cells at the molecular level, providing more physiological and pathological diagnostic information for clinics. [0003] Magnetic Resonance Imaging (MRI) is the use of magnetic resonance phenomena to obtain electromagnetic signals from the human body and reconstruct human body information. It can obtain tomographic images in any direction, three-dimensional volume images, and even four-dimensional images of space-spectrum distribution. . [0004] The combination of PET / MRI c...
