Simulated operation planning method based on medical image

Abstract

The invention belongs to the fields of image processing and pattern recognition, and relates to a simulated surgery planning method based on medical images. The method comprises the following steps: a changeable curve is generated in the three-dimensional space; a plurality of operation points are arranged on the curve; the curve is controlled and adjusted by the operation points; additional operation points can be arranged on the curve, or the operation points on the curve can be reduced; and according to the planned curve, the cutting angle of a scalpel is calculated, and the scalpel is arranged reasonably, so that cutting processes in future operations can be facilitated. Compared with the prior medical image processing system, the invention creatively introduces a simulated surgery planning system which performs virtual surgery path planning to lesion sites on the basis of three-dimensional CT imaging, so that the invention is of critical importance and use value to being proficient at operative procedures and reducing operative risks.

Description

technical field [0001] The invention belongs to the technical field of image processing and pattern recognition, and in particular relates to a simulated operation planning method based on medical images. Background technique [0002] Simulated surgery is a process in which a computer is used to generate a virtual surgical scene, and medical staff conduct preoperative simulations through simulated surgical instruments and formulate a surgical plan. With the development of computer technology, image processing technology and virtual reality technology, simulated surgery has become a research hotspot in recent years. It can improve the safety and accuracy of surgery and has attracted widespread attention. In order to achieve puncture needle puncture or scalpel incision in simulated surgery, traditional puncture and incision rely solely on the doctor's hand feeling and experience, while the planning of puncture and surgical path, puncture point, puncture depth and scalpel incis...

Problems solved by technology

However, the system can only accept computer instructions, and cannot realize a fully interactive three-dimensional virtual surgical environment, and cannot perform flexible surgical planning, nor can it realize virtual cutting operations; the Department of Computer Science and Technology of Tsinghua University proposed a surgery-oriented The simulated surgery interaction in the same way, but can only realize the simulated surgery according to a specific route, such as the simulated surgery of the hip joint, the interactive operation can only be carried out in accordance with the prescribed order, and the simulated surgery system of the present invention can be applied to the simulated surgery of any organ , and can be cut and operated in any order, more convenient and flexible; Anhui Medical University proposed the application research of using rapid prototyping technology to establish a bone model to simulate surgery in 2005. This technology is to input
