Abstract

The invention relates to the technical field of medical experimental facilities, and discloses a small animal brain three-dimensional positioning system for magnetic resonance imaging scanning equipment. The system comprises a magnetic compatibility small animal brain three-dimensional positioning device used for conducting brain three-dimensional positioning on the head of a small animal and a magnetic resonance small animal radio frequency coil device which is used for receiving a magnetic resonance radio frequency signal in the X axis direction and transmitting the signal to a magnetic resonance imaging system. According to the system, in the piercing implementation process, magnetic resonance scanning can be carried out on an experimental animal, the magnetic resonance radio frequency signal is received through the small animal radio frequency coil, the signal is transmitted to the magnetic resonance imaging system, a magnetic resonance scanning image can be utilized for guiding and monitoring the piercing process, the magnetic resonance imaging scanning equipment can be utilized for guiding a small animal three-dimensional positioning operation or conducting positioning experiments such as piercing and stimulation exertion.

Description

technical field [0001] The invention relates to the technical field of medical experiment equipment, in particular to a small animal brain stereotaxic system applicable to operations or experiments such as puncturing and stimulating the brain of small animals under the guidance of magnetic resonance scanning equipment. Background technique [0002] Brain stereotaxy is an essential interventional device in the minimally invasive brain surgery of small animals. Its principle is to obtain specific subcortical brain tissue structures based on three-dimensional coordinates determined by extraskull markers or other reference points. position, so that the needle insertion point of the interventional device can be accurately set. When the interventional device enters the brain tissue, it is necessary to monitor the position of the interventional device and the surrounding tissue information in real time, so as to guide the device and ensure the smooth operation and safety of the ope...
