Embodiment Construction

[0038] The following describes a preferred embodiment of the present invention with reference to the accompanying drawings to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned herein.

[0039] as attached figure 1 Shown is a schematic diagram of the unit structure of this embodiment. This embodiment is a preoperative auxiliary planning system based on virtual reality, which mainly consists of two subsystems. The first part is the visualization part of brain medical images, and the second part is the preoperative planning part. Among them, the brain medical image visualization part includes a medical data import unit, a brain structure segmentation unit, a blood vessel branch segmentation unit, a registration unit, and a visualization model establishment unit.

[0040]In this embodiment, the work...

Abstract

The invention discloses a virtual reality based preoperative auxiliary planning device which comprises a medical image visualization subsystem and a preoperative planning subsystem, wherein the medical image visualization subsystem comprises a medical data import unit, a brain structure segmentation unit, a vascular branch segmentation unit, a registration unit and a visualization model establishment unit; and the preoperative planning subsystem comprises a visual field adjustment unit, an operation planning unit, a result storage and export preview unit. By adopting the virtual reality basedpreoperative auxiliary planning device disclosed by the invention, the problems of different visual level and lack in stereoscopic impression of medical images can be solved; and a complete and clearvisualization model is established for each patient, so that preoperative planning has an immersion sense and a visual sense.

Description

technical field [0001] The invention relates to the fields of electronics and medicine, in particular to a preoperative auxiliary planning device based on virtual reality. Background technique [0002] Clinical operation is an important means of diagnosis and treatment in modern medical care, and it is currently the implementation plan of complex surgical operations. The demand for clinical operations is huge. Taking epilepsy as an example, in 2016, globally, the proportion of patients with active epilepsy was 6.38 patients per 1,000 people, while the proportion of patients with permanent epilepsy was 7.60 patients per 1,000 people, and the incidence rate of epilepsy reached every 10 There were 61.44 cases per 10,000 people, and the annual cumulative incidence reached 67.77 cases per 100,000 people. Therefore, a large number of epilepsy patients need to be treated by brain surgery. Epilepsy surgery includes partial resection, resection of large brain tissue, cut off of ep...
