Intelligent positioning system and method for spinal cord body surface puncture approach point based on multi-mode medical fusion image

Abstract

The invention discloses an intelligent positioning system and method for a spinal cord body surface puncture approach point based on a multi-mode medical fusion image, and belongs to the field of medical science. An ultrasonic technology is used for collecting spinal images in real time; a two-dimensional ultrasonic image and spatial position information corresponding to the two-dimensional ultrasonic image are obtained, and a three-dimensional ultrasonic reconstructed diaphragm is obtained through reconstruction; a spinal multi-mode medical image which is obtained through a non-ultrasonic mode is input into the system; then, through fusing, the fusion image is obtained. The fusion image can be used for puncture training or operation assistance. Based on an image processing technology, thetechnical weakness of a traditional ultrasonic imaging technology for spinal bony structure imaging is overcome; the defects of large puncture damage, radiation damage and step complexity and time consumption are overcome, and in clinical practical operation and simulation training, current spinal cord operations are pushed greatly.

Description

technical field [0001] The invention relates to the field of medicine, in particular to an intelligent positioning system and method for spinal cord body surface puncture entry points based on multi-mode medical fusion images. Background technique [0002] Spinal cord-related diseases include spinal cord tumors, trauma, and degenerative diseases. In recent years, the incidence of spinal cord-related diseases has been increasing, seriously affecting people's health and working ability. In my country, the diagnosis and treatment of spinal cord-related diseases are mainly undertaken by spine surgeons and neurosurgeons, and surgical treatment is one of the main treatment methods. At present, spinal cord surgery is mainly divided into two categories: open surgery and minimally invasive surgery. With the development of medical equipment and navigation technology in recent years, minimally invasive surgery has gradually become the mainstream due to its advantages of less damage, le...

Problems solved by technology

At present, ultrasound-guided spinal nerve block and epidural anesthesia puncture are widely used, and ultrasound is also combined with other medical images such as CT and MRI to form two-dimensional fusion images and be used to assist navigation and positioning. Related equipment and image processing software The use of ultrasonic imaging can give full play to the advantages of real-time, portable, and radiation-free ultrasound images. However, ultrasonic imaging is more suitable for soft tissue structures, while for bone structures, due to the existence of sound wave attenuation, distortion and reflection, ultrasonic bone images are blurred and surface burrs are difficult. Clear imaging and precise positioning lead to limited universality and reliability of existing technologies in practical applications

[0006] In addition, in view of the high technical threshold and long learning curve of minimally invasive operation techniques, young operators do not yet have sufficient knowledge and experience. Mentoring at the beginning of the job is particularly difficult

Existing training methods, systems and equipment can better simulate the overall operation process and help beginners understand the operation steps and identify typical anatomical structures. However, there are problems with single models and operations, which are not enough to deal with the ...
