Problems solved by technology

However, in MRI examination, only using the imaging method, it is impossible to accurately judge the specific condition of the patient's diseased part, especially when performing surgery, it is impossible to accurately grasp the size and specific location of the diseased part
However, the existing methods of using 3D printing to embody are too complicated, difficult to operate, and inaccurate in positioning

Embodiment 1

[0066] When in use, put the patient's head on the mounting plate 6, push the positioning adjustment lever 14 against both sides of the patient's head, and rotate slightly 45-60° to clamp the patient's head, just keep in contact , without too much clamping, and then record the indication scale on the outside of the vertical plate 11 on each positioning adjustment rod 14, and then move the patient into the MRI scanner 1, and then during the movement, the scanner is used to indicate laser signal reception 9 (the signal emitted by the laser transmitter 26 passes through the light-transmitting positioning hole 13 and is received by the laser signal receiver 27, and the indicator light is set when the positioning is completed. When the laser signal receiver 27 is interrupted After that, the light is off), scan the patient, after the scan is completed, the data is input to the 3D printer 10, then the mounting plate 6 is removed, and each scale on the positioning adjustment rod 14 is a...

Embodiment 2

[0068] The difference from Example 1 is that the patient’s abdomen is checked in this example, and the operation is the same as in Example 1. During implementation, since the shape of the abdomen and the head are different, the contact head and the positioning adjustment rod of the present invention can be provided with more Several groups, easy to adjust according to the shape.

Embodiment 3

[0070] The difference from Example 1 is that the chest cavity is inspected. At this time, the patient’s arm is placed outside the vertical board to avoid affecting the chest cavity inspection. During the inspection, the patient can also change the posture and do more inspections to meet the requirements. Multiple sets of data collection.

[0071] It can be seen from the above that the present invention is not limited to a single part of the human body, and can be applied to any part of the human body for accurate positioning, and has wide applicability; during positioning, it can be recorded and registered according to the data display of the positioning adjustment lever, It is convenient to retain data in the subsequent sequence. At the same time, after modeling, the positioning mechanism originally used for scanning is directly used to carry out the supporting structure of 3D printing. There are many positioning points and support points, which is convenient for fast printing...

Abstract

The invention discloses an auxiliary device for accurate positioning in a nuclear magnetic resonance examination. The auxiliary device comprises a nuclear magnetic resonance scanner and a 3D printer;an external computer of the 3D printer is connected with an image output port of the nuclear magnetic resonance scanner; a mounting plate is arranged in a mounting groove; a light-transmitting positioning hole is formed in one of corners of the upper end of a vertical plate; two sides of the inner wall of the nuclear magnetic resonance scanner are respectively provided with a laser transmitter anda laser signal receiver; the inner bottom part of each of elongated grooves is provided with scales; an internal threaded portion which can be in threaded connection with a corresponding external threaded portion is arranged in each of half-thread holes; and one end of a positioning adjustment rod is further fixedly provided with a contact head. The auxiliary device is not limited to a single part of a human body, can be optionally suitable for accurate positioning of all parts of the human body, and has wide applicability; and during printing, a positioning mechanism used for scanning originally and a supporting structure for 3D printing are directly utilized, and due to numerous positioning points and supporting points, fast printing operation is realized conveniently, and efficiency ishigher.

Description

technical field [0001] The invention belongs to the technical field of nuclear magnetic resonance examination, and in particular relates to a precise positioning auxiliary device for nuclear magnetic resonance examination. Background technique [0002] Nuclear Magnetic Resonance uses the principle of nuclear magnetic resonance, according to the different attenuation of the released energy in different structural environments inside the material, and through the detection of the emitted electromagnetic waves by an external gradient magnetic field, the position and type of the atomic nucleus that constitutes the object can be known. This can be mapped into an image of the structure inside the object. Magnetic resonance imaging is the latest medical imaging technology using the principle of nuclear magnetic resonance. It has excellent effects on brain, thyroid, liver, gallbladder, spleen, kidney, pancreas, adrenal gland, uterus, ovary, prostate and other solid organs as well as...
