Problems solved by technology

[0004] In the prior art, since PET equipment requires a highly sensitive detection mechanism to detect tracers injected into the human body, the hardware structure and algorithm of PET equipment are complex and expensive
When PET-CT detection and PET-MR detection are required, PET-CT equipment and PET-MR equipment need to be purchased at the same time. The PET part is duplicated, the cost is high, and the repeated purchase of PET equipment is a waste of resources.

Embodiment 1

[0044] Such as Figure 1-Figure 4 As shown, this embodiment provides a multi-modal imaging system, including CT equipment 2, MR equipment 3, PET equipment 1, a guide assembly and a support assembly, the guide assembly can be a guide rail 4, and the support assembly can be a bottom support seat 7 , The guide rail 4 is arranged on the bottom support base 7 .

[0045] In this embodiment, the CT device 2 has a CT scanning channel, the MR device 3 has an MR scanning channel, the PET device 1 has a PET scanning channel, and at least one of the PET device 1, the CT device 2, and the MR device 3 is configured to be movable so that at least two of the PET scanning channel, the CT scanning channel and the MR scanning channel are arranged oppositely, so that at least two of the CT device 2 , the MR device 3 and the PET device 1 can be used together.

[0046]This embodiment is described by taking the PET device 1 as an example that can move relative to the MR device and the CT device. T...

Embodiment 2

[0061] This embodiment provides a multimodal imaging system, the structure of which is roughly the same as that in Embodiment 1. The difference from Embodiment 1 is that, as Figure 5-Figure 7 As shown, the driving assembly 5 includes a second motor 54, a lead screw 55 and a nut matched with the lead screw 55, the second motor 54 is connected to the lead screw 55, the nut is fixed to the PET equipment 1, and the second motor 54 drives the lead screw when rotating 55 rotates, thereby driving the nut to slide on the lead screw 55, and then driving the PET equipment 1 to move.

[0062] The driving assembly 5 can also be other driving structures, such as a rack and pinion structure, specifically, it includes a third motor, a gear, and a rack matched with the gear, the third motor drives the gear, and the rack is fixed to the PET device 1. The meshing transmission of the gear and the rack can also realize the movement of the PET equipment 1 along the guide rail 4 .

Embodiment 3

[0064] This embodiment provides a multi-modal imaging system on the basis of the above-mentioned embodiments, and the difference from the above-mentioned embodiments is that, as Figure 8-Figure 10 As shown, the two ports of the PET scanning channel of the PET device 1 can be selectively aligned with the port of the CT device scanning channel or the port of the MR scanning channel, respectively.

[0065] In this embodiment, the MR equipment 3 and the CT equipment 2 are arranged in series, and the scanning channels of the MR equipment 3 and the CT equipment 2 are coaxial. The axes of the scanning channels of 2 may also be different, and an appropriate driving mechanism is required to move the PET device 1 to a position aligned and coaxial with the scanning channels of the MR device 3 and the CT device 2 .

[0066] The guide assembly is arranged between the MR equipment 3 and the CT equipment 2 and extends along the serial direction. The PET equipment 1 is slidably connected wit...

Abstract

The invention discloses a multi-mode imaging system. The multi-mode imaging system comprises CT (computed tomography) equipment, MR (magnetic resonance) equipment and PET (positron emission tomography) equipment, wherein the CT equipment is provided with a CT canning channel; the MR equipment is provided with an MR scanning channel; the PET equipment is provided with a PET scanning channel; at least one of the PET equipment, the CT equipment and the MR equipment can be moved, and at least two of the PET equipment, the CT equipment and the MR equipment are correspondingly arranged. The multi-mode imaging system has the advantages that the PET equipment, the CT equipment and the MR equipment can be matched to form PET-CT equipment, PET-MR equipment or MR-CT equipment; compared with the priorart with purchasing of multiple groups of equipment, the PET equipment, the CT equipment and the MR equipment can be independently operated and can be jointly used, so that the waste of equipment andfund due to repeated purchase of equipment is avoided, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a PET-CT-MR multimodal imaging system. Background technique [0002] In the process of medical diagnosis and treatment, the concept of "early detection, timely prevention and treatment" is a "good prescription" for many patients. Today, with the advancement of science and technology, medical equipment and instruments in the medical field are also undergoing continuous reform and innovation. The promotion and application of advanced medical examination methods and technologies in clinical practice has enabled human beings to realize their dream of early diagnosis of malignant tumors. accomplish. [0003] PET, PET-CT and PET-MR technologies are all high-end medical imaging diagnostic technologies in the world. PET is an imaging inspection method that uses large-scale high-end imaging equipment to observe the distribution of imaging drugs injected into the body in vivo. ...
