Embodiment 1

[0021] figure 1 It is a schematic diagram of the present invention, as shown in the figure, in the figure, the circle represents a marker sheet, a pulmonary nodule puncture positioning technology for marker-assisted mixed reality technology, and the method includes the following steps:

[0022] (1) Place at least 3 markers made of bone-like material on the chest of the human body, at least 3 markers form a plane, and mark the positions where the markers are placed;

[0023] (2) CT scanning generates two-dimensional images;

[0024] (3) The 2D image is obtained by 3D reconstruction technology to obtain a 3D model;

[0025] (4) Use mixed reality equipment to accurately match the 3D model with the painted marks on the human body;

[0026] (5) Confirm the position, angle and depth of the puncture needle;

[0027] (6) After the needle is inserted, the surface of the lung segment where the pulmonary nodule is located is stained and localized. Generally, IgG staining agent is used...

Abstract

The invention relates to a pulmonary nodule puncture positioning technology of a mark point assisted mixed reality technology. The pulmonary nodule puncture positioning technology includes the steps:(1) placing at least three markers made of imitation bone materials at the chest of a human body, forming a plane by the markers and marking the placement positions of the markers by coloring; (2) generating two-dimensional images by CT (computerized tomography) scanning; (3) performing a three-dimensional reconstruction technique on the two-dimensional images to obtain a 3D (three-dimensional) model; (4) accurately matching the 3D model with the colored markers on the human body by a mixed reality device; (5) confirming the position, the angle and the depth of a puncture needle; (6) positioning the surface of a pulmonary segment with a pulmonary nodule by dyeing after needle insertion. The position of the pulmonary nodule is accurately positioned by the mixed reality technology without repeated scanning and repeated puncture, the pain of a patient is greatly relieved, surgical efficiency is improved, upper pulmonary lobe positioning effects are better, and errors are at a millimeter level.

Description

technical field [0001] The invention belongs to the field of image recognition and medical image processing, and relates to a pulmonary nodule puncture positioning technology based on a marker-assisted mixed reality technology. Background technique [0002] Clinically, it is customary to call the round or irregular space-occupying lesions of the lungs less than three centimeters called pulmonary nodules, which is a general term for which the specific nature of such space-occupying lesions has not yet been determined. Pulmonary nodules can be benign or malignant. Nodules are divided into solid nodules, part solid nodules and ground glass nodules. Part-solid nodules have the highest probability of malignancy, followed by ground-glass nodules and solid nodules. [0003] In order to be able to characterize pulmonary nodules early, in the prior art, CT-guided percutaneous lung biopsy is an important method for clinical diagnosis of benign and malignant pulmonary nodules and lun...
