Problems solved by technology

However, for the current 3D visualization technology of medical images, the segmentation of organs cannot be realized, and it is difficult for doctors to intuitively see which segment the tumor is in from the 3D image
In addition, the current 3D visualization technology of medical images only provides 3D viewing function, but cannot realize preoperative simulated resection and surgical risk assessment

Embodiment 1

[0034] refer to figure 1 As shown, the present invention discloses a surgical simulation system based on a 3D model of human organs, including a CT data import unit 10, a CT image segmentation unit 20, a three-dimensional modeling unit 30 and a surgical simulation unit 40, wherein:

[0035] The CT data import unit 10 is used for importing CT data, and the CT data includes CT images, patient information, hospital information, CT machine model information and CT slice accuracy information. The CT data importing unit 10 has a CT data preview module and a CT image preprocessing module, the CT data preview module is used to view relevant content of the CT data, and the CT image preprocessing module is used to judge whether the CT image is inverted, and the inverted CT image Adjust to the correct orientation.

[0036] The CT image segmentation unit 20 is used to segment soft tissue organs, tumors, blood vessels and hard tissues on the CT image, which includes a soft tissue organ se...

Embodiment 2

[0044] The invention discloses a surgical simulation method based on a 3D model of human organs, which is implemented based on the surgical simulation system of Embodiment 1. The method includes the following steps:

[0045] S1. Using the CT data import unit 10 to import CT data.

[0046] S2. Using the CT image segmentation unit 20 to segment soft tissue organs, tumors, blood vessels and hard tissues on the CT image, and segment the soft tissue organs according to the blood vessels. Step S2 specifically includes the following steps:

[0047] S21. Segmentation of soft tissue organs, selecting positions of soft tissue organs on the CT image through human-computer interaction, and automatically segmenting soft tissue organs. The position of the soft tissue organ on the CT image is selected by placing seed points through human-computer interaction, and the computer automatically segments the soft tissue organ. For large soft tissue organs, the position of the soft tissue organ is...

Abstract

The invention discloses an operation simulation system based on a human body organ 3D model, comprising a CT data input unit, a CT image segmenting unit, a three-dimensional modeling unit and an operation simulation unit; the CT data input unit is used for inputting CT data; the CT image segmenting unit is used for segmenting soft tissue organ, cancer, blood vessel and hard tissues from the CT image, and segmenting the soft tissue according to the blood vessel; the three-dimensional modeling unit is used for establishing a three-dimensional model of every section of soft tissue organ, cancer, blood vessel and hard organ, and integrating to be a human body organ 3D model; the operation simulation unit comprises an operation simulation excision module, an excision result analysis module, an operation simulation measuring module, and an operation simulation risk evaluating module. The invention further discloses an operation simulation system based on the human body organ 3D model. The system and the method can directly acquire the section of the organ suffering from cancer and accurately position the cancer, thereby further reducing the operation difficulty and risk, and realizing the pre-operation simulation excision and operation risk evaluation.

Description

technical field [0001] The invention relates to the technical field of surgical simulation, in particular to a surgical simulation system and method based on a 3D model of human organs. Background technique [0002] At present, for operations on soft tissue organs such as the liver and lungs, since the tumor is usually inside the organ, doctors still need to find the location of the tumor based on experience during the operation. The main problem is that it is difficult for the doctor to find the location of the tumor. It also increases the risk of surgery. As we all know, some organs in the human body are segmented organs. For example, the liver can be divided into five lobes and eight segments through the arteries, and the lungs can be divided into five lobes and twenty segments through the arteries. If you know which segment of the organ the tumor is located in before the operation , the situation will be different. For doctors, it is much easier to find the segment of t...
