Problems solved by technology

[0004] Based on this, the inventors of the present application found that although intraoperative CT positioning is accurate, safe, and fast, the dose used is high, and surgical scenarios that require multiple positioning will lead to accumulation of patient exposure doses; equipment usage scenarios are limited , cannot be installed in unshielded spaces such as operating rooms, and has great restrictions on shuttles in CT shielded rooms and sterile surgical environments; the equipment is expensive and cannot be popularized in conventional surgical departments
Unable to meet the precise, convenient and efficient positioning requirements in surgery

Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0022] Digital radiography (DR) is currently the most widely used X-ray imaging equipment. For surgical positioning scenarios, mobile DR or C-arm is generally used. Portable DR such as orthopedics or interventional therapy has high spatial resolution and imaging speed. Fast, low price, less radiation, etc., but it can only provide two-dimensional tissue stack images, often unable to directly observe tiny lesions with small differences in tissue density. On the other hand, due to respiratory movement, setup errors, and posture differences, there are often large differences between intraoperative DR photography and preoperative diagnostic imaging, and the spatial mapping relationship between medical 3D images and 2D proje...

Abstract

The invention discloses an intraoperative preset area positioning method and device, a storage medium and electronic equipment, and the method comprises: obtaining a medical three-dimensional image ofa preset area, and carrying out the extraction of an ROI (region of interest) of the medical three-dimensional image; acquiring a plurality of two-dimensional projection plain films with different angles of the ROI in an operation; generating an ROI and an area mask corresponding to each two-dimensional projection plain film according to the plurality of two-dimensional projection plain films with different angles, the medical three-dimensional image and the deep learning network model; and performing three-dimensional space mapping on the region masks of the ROI in the plurality of two-dimensional projection plain films with different angles and the plurality of two-dimensional projection plain films with different angles, and generating three-dimensional positioning information of the ROI in the operation so as to position a preset region. According to the intraoperative preset area positioning method and device, the storage medium and the electronic equipment, accurate three-dimensional positioning can be achieved, the problem that in the prior art, the dosage of conventional operation positioning is too high is solved, and the requirement for accurate, convenient and efficientpositioning in an operation is met.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a positioning method, device, storage medium and electronic equipment for an intraoperative preset area. Background technique [0002] Fine operations such as puncture, interventional and minimally invasive operations are currently widely used in clinical examination and treatment. For internal organ lesions (such as nodules, tumors and other regions of interest) that have no clear boundaries and cannot be directly observed, computerized tomography (English full name: computed tomography, English abbreviation: CT) or magnetic The three-dimensional image of resonance image (full English name: Magnetic Resonance, English abbreviation: MR) is used for preoperative diagnosis. In fine surgery such as puncture, intervention and minimally invasive after diagnosis, precise positioning and fine treatment are required. Therefore, precise medical imaging technology is requ...
