Problems solved by technology

However, ultrasound guidance is not widely used clinically, especially in orthopedic minimally invasive treatment. Doctors grasp the ultrasonic image features of each bone anatomical structure under ultrasound, and conduct artificial anatomical structure discrimination, which has poor clinical practicability; (2) The imaging characteristics of ultrasound itself determine that when encountering interfaces such as gas and bone, the rear structures cannot be displayed, and only provide Give doctors local intraoperative three-dimensional bone structure information; (3) The existing preoperative and intraoperative structural fusion methods require the operator or doctor to manually find the key points of preoperative structural matching, which requires a long learning curve and registration fusion limited precision

Embodiment Construction

[0030] Such as Figure 1-Figure 4 As shown, an intelligent ultrasonic multimodal navigation system includes: an ultrasonic real-time acquisition and transmission module, which transmits a real-time two-dimensional ultrasonic image sequence from an ultrasonic imaging device to an intelligent image analysis terminal through a high-performance video transmission card; image pose acquisition The module uses the magnetic locator to collect the three-dimensional spatial information of the ultrasonic imaging probe, and combines the ultrasonic probe calibration technology to obtain the spatial pose of the two-dimensional ultrasonic image sequence, which is used to assist intelligent three-dimensional reconstruction; the adaptive space-time feature recalibration bone The structure recognition module proposes a multi-scale convolutional neural network algorithm based on adaptive space-time feature recalibration, realizes the intelligent detection and recognition of bone structures in 2D ...

Abstract

The invention discloses an intelligent ultrasonic multi-modal navigation system and an intelligent ultrasonic multi-modal navigation method, which can be used for providing real-time three-dimensionalintraoperative information guidance for doctors in a multi-dimensional navigation information presentation mode through intelligent ultrasonic collection, positioning and real-time image processing integrated with a space-time characteristic mechanism in an intraoperative non-radiative operation environment.

Description

technical field [0001] The invention relates to the technical field of surgical navigation, in particular to an intelligent ultrasonic multi-modal navigation system and method. Background technique [0002] Minimally invasive surgery is an important trend in the development of surgery in recent years. In orthopedics, there are more and more minimally invasive treatment techniques, such as transforaminal endoscopy, hip arthroscopy, percutaneous pedicle screw, percutaneous vertebral body shaping, and intramedullary nailing techniques. Minimally invasive treatment achieves precise surgery with as little surgical trauma as possible. In order to meet this demand, intraoperative images are usually used for guidance. The most commonly used clinically are intraoperative X-ray and computed tomography (CT). The use of X-rays will bring a large amount of radiation, which poses a potential threat to the health of patients and doctors. At the same time, due to the non-real-time nature o...
