Embodiment 1

[0035]The preoperative planning and surgical virtual reality simulation method for minimally invasive cardiac surgery provided by the embodiment of the present invention specifically includes the following steps:

[0036] (1) Medical image data input: the system uses eFilm Workstation (Version 2.0.1) medical image processing software to preprocess the data from CT or MRI, and artificially segment two-dimensional image data sets with different enhancement phases, so that Establish a normal image coordinate system to import medical images scanned by CT, MRI, PET, etc. into the computer;

[0037] (2) Three-dimensional modeling: Using computer image processing technology, the obtained two-dimensional medical images are reconstructed into three-dimensional three-dimensional images in three-dimensional space. The 3D modeling is mainly divided into four steps: first, the data coincidence processing system is used to process the collected two-dimensional image data to obtain the forwa...

Abstract

The invention discloses a preoperative planning and surgery virtual reality simulation method of the minimally invasive cardiac surgery. The method comprises the steps that firstly, data from CT or MRI is preprocessed by means of the eFilm workstation medical image processing software, a normal image coordinate system is built, and medical images scanned by the CT, the MRI and PET are imported into a computer; the obtained two-dimensional medical images are reconstructed in a three-dimensional space to obtain three-dimensional images; the two-dimensional voxel-level medical images are imported into a Unity 3D engine, the conversion from the two-dimensional images to the three-dimensional images is conducted by the computer, and real-time dynamic three-dimensional images are generated; a surgery planning and simulation platform is built by means of the Unity 3D engine, virtual reality patient data is input, warning and reminding are conducted on wrong or risky operating steps, and meanwhile the simulation surgery effect of a doctor is assessed. According to the method, detailed preoperative planning and surgery simulation can be conducted through the virtual reality environment before a surgery.

Description

technical field [0001] The invention belongs to the technical field of preoperative assistance, in particular to a method for preoperative planning and virtual reality simulation of minimally invasive heart surgery. Background technique [0002] The morbidity and mortality are very high. According to the "China Cardiovascular Disease Report": the prevalence of cardiovascular disease in my country is on the rise. It is estimated that there are 290 million patients with cardiovascular disease in the country, and their mortality rate is extremely high. In 2014, the national 2 out of every 5 deaths are due to cardiovascular disease. However, compared with the treatment of general tumor surgery, the effect of cardiovascular disease after effective surgical treatment is remarkable: for patients with severe symptoms before surgery, the changes after surgery are immediate. In order to ensure the smooth progress of the operation, reasonable and reliable preoperative planning is essen...
