Method for conducting MR registration through amplification of bone region and tool design method of MR registration

Abstract

The invention belongs to a method of medical treatment imaging, and particularly relates to a method for conducting MR registration through amplification of a bone region and a tool design method of MR registration. Before an operation, an exposed bone region is used as an osseous positioning region for three-dimensional reconstruction, according to the osseous positioning region, an individualized veneer is designed and connected to an extrinsic reference mark through a connecting rod, the series of components are made into a reference mark tool through a 3D printing technology, before the operation, skeleton and peripheral tissue data of a patient and digitalized three-dimensional information of the reference mark tool are input into a holographic computer, in the operation, the sterilized reference mark tool is installed on the corresponding osseous positioning region, a relatively small operation bone region is amplified into a large 3D printing reference mark, the holographic computer realizes registration by recognizing the reference mark on the reference mark tool, in this way, virtual skeletons and other anatomical structures of the patient are overlapped onto the real bodyof the patient, and the operation is easy.

Description

technical field [0001] The invention belongs to medical imaging methods, and in particular relates to a method for expanding a bone region for MR registration and a tool design method thereof. Background technique [0002] Surgical operations require a full understanding of the deep lesions in the human body, but previously they could only be understood through adequate incision exposure, radiography, and Doppler ultrasound. [0003] In recent years, MR technology has provided a new option. The CT and MRI information of the patient's bones and surrounding tissues are input into the head-mounted (glasses) holographic computer through three-dimensional reconstruction. After registration during the operation, the patient can be The virtual three-dimensional image of the bone and surrounding tissue is presented in the patient's body, which fully helps the operator to understand the deep situation of the operation area in real time, regardless of whether the incision is exposed o...

Problems solved by technology

However, in surgery, only a small part of the bone can be exposed through incision. These limited bone areas, as registration mark areas, will greatly affect the accuracy and process of registration. Therefore, the present invention uses 3D printing The fiducial marker tool, which amplifies the smaller bone area into a larger 3D printed registration marker, solves the problems of difficult registration process and low registration accuracy in intraoperative MR
