Problems solved by technology

[0003] Most of the assisting methods for lung segment surgery in the prior art are to display the patient's CT image or three-dimensional structure on the PC. The doctor can infer the position of the lung segment according to the direction of the patient's pulmonary blood vessels and trachea, and then perform segmentectomy. The CT image or three-dimensional structure of the patient is displayed on the PC, but the effect is not good when the doctor views it in practical applications, which is of limited help to the doctor's surgical work

Embodiment 1

[0064] like figure 1 Shown: This embodiment discloses an augmented reality assisted surgery method, including the following steps:

[0065] 101. Acquire lung CT image data of a patient;

[0066] 102. Process the acquired lung CT image data by using region growth and image filling algorithms to obtain pulmonary blood vessel data and trachea data;

[0067] 103. According to the obtained pulmonary blood vessel data and trachea data, construct an edge mesh model;

[0068] 104. Import the constructed edge mesh model into a mixed reality device for display for the doctor to observe.

[0069] The step 102 in this embodiment further includes the following sub-steps:

[0070] 102A1. Select the seed point of the trachea in the acquired CT image of the lung, and preset the threshold range in advance, and then use the region growth algorithm to acquire the trachea image;

[0071] 102A2. Use an image filling algorithm to extract the noise on the acquired trachea image;

[0072] 102A3....

Abstract

The invention relates to an augmented reality auxiliary operation method, comprising the following steps: 101, obtaining lung CT image data of a patient; 102, using region growth and image filling algorithm to process the acquired lung CT image data to obtain pulmonary blood vessel data and tracheal data; 103, according to the data of pulmonary vessels and trachea, constructing the edge mesh model; 104, and importing the edge mesh model into the hybrid reality device for display for doctors to observe. The augmented reality assisted surgical method provided by the invention can realize the display of the lung tissue structure of a patient on a mixed reality device, and is more stereoscopic and clear compared with the traditional PC terminal result display.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to an augmented reality assisted surgery method. Background technique [0002] In today's world, due to the decline in air quality, people smoke or smoke second-hand smoke, which leads to an increasing incidence of lung cancer. Lung cancer has endangered the health of our people and threatens human life. The early treatment of lung cancer is to remove the lungs infected by cancer. The lung is composed of several lung lobes, and the lung lobes are composed of several lung segments. How to remove only the infected lung segment as small as possible and retain most of the healthy lung tissue is a major problem in the surgical treatment of lung cancer. [0003] In the prior art, most of the auxiliary methods for lung segment surgery are to display the CT image or three-dimensional structure of the patient on the PC. The CT image or three-dimensional structure of the patien...
