Problems solved by technology

The calculation process of the former method is complex and the production cost of the calibration model is high, and it is necessary to repeatedly image and analyze the three-dimensional calibration model in different positions to obtain the position offset of the control point, which is difficult in practice
In the latter method, the design parameters of the gradient coil are only a major factor of image deformation, and the influence of other hardware and software modules of the magnetic resonance system on image deformation is not considered, so the image correction results often fail to meet the requirements
[0005] 2. When doctors perform magnetic resonance interventional therapy, they usually observe the magnetic resonance images of the lesion with the naked eye, and place the surgical instruments at the ...

Embodiment 1

[0061] Embodiment 1: as shown in Fig. 3 and Fig. 4, the calibration mold 9 of the present embodiment comprises a rectangular calibration mold body 91 of 300mm * 240mm * 200mm made of plexiglass material, and the calibration mold body 91 has five other parts except the bottom surface. The surfaces are similar, and each surface has a characteristic layer 92 with a certain thickness, and the surfaces are sealed and connected by bonding or other methods. A group of spheres (such as cod liver oil spheres) as feature points 93 are arranged at intervals inside each feature layer 92 , and all the feature points 93 on the five surfaces together form the feature point set I. Corresponding to the position of each feature point 93 on the outer surface of each feature layer 92, a pit is set as a feature point 94, and the feature points 94 on the five outer surfaces together form the feature point set II. In calibration mold body 91 inside, promptly in the space that six wrap up is calibrat...

Abstract

The present invention is surgical operation system under the guide of magnetic resonant image and the operation navigating method. The surgical operation system includes magnetic resonant imaging equipment, a tracking system, a surgical instrument, a sick bed, a control and display device, a computer with relevant software. It features the calibrating pin and calibrating mode, and the tracer with different coordinate systems for measuring pose and calibrating. The present invention can realize the precise location of the operational equipment relative to the magnetic resonant image and operation navigation.

Description

technical field [0001] The invention relates to a surgical system and a control method, in particular to a magnetic resonance image-guided surgical system and a surgical navigation method. Background technique [0002] Interventional surgery is a major development direction of modern surgery. The difference between interventional surgery or interventional therapy and traditional surgery is that it does not require surgery, and only requires a small incision to insert special catheters, cryo-needles, radiofrequency ablation needles, Surgical instruments such as guide wires penetrate into the lesion or surgical target in the human body, and then achieve the purpose of treatment through various physical / chemical effects, so as to solve the tumor resection, tissue biopsy, artificial equipment placement etc. Interventional surgery has the characteristics of no surgery, precise damage, small trauma, and fast recovery. It is considered to be an ideal alternative to many traditiona...
