Description

A system that uses virtual reality to simulate X-ray studios

The present invention relates to a system for simulating an X-ray studio, in particular to a system that uses virtual reality to simulate an X-ray studio.

In the teaching of imaging medicine, most of the teaching is based on the actual clinical shooting of the patient. For the newly recruited personnel, there is no training. Because X-ray photography will only know the result after pressing the shooting button, a radiologist is required. One's own experience and imagination are used to predict the results of shooting. Experience and spatial understanding are the most important for radiologists. Therefore, for newcomers, these two are lacking. In the process of learning, the rate of rejects is often increased, which is not possible when there is no patient. Practice lacks experience. Generally, prostheses can be used for shooting exercises, but they are expensive and cannot effectively simulate the patient's posture or state during shooting.

The present invention uses virtual reality (Virtual Reality, VR) technology to virtual human body, which is provided to personnel for practice or examination use, thereby improving the ability of radiologists and providing patients with more complete medical treatment.

Comparison between the present invention and the current technology:

When students practice in school, they can only practice through the placement of their classmates, but they cannot know whether the actual shooting is correct. Because they can't actually shoot, the practice effect is limited.

The present invention uses the virtual reality simulation photography room to provide students with a learning method. An X-ray image can be obtained by simulating positioning exercises in the virtual space, so that there is a basis for correctness. This method does not have radiation exposure and can be targeted at positioning Go practice.

Comparison of three teaching methods:

1. Actually take pictures of the patient’s tutor and guide:

Disadvantages: The patient's radiation dose will increase during the re-exposure, the online work speed will be reduced, the special positioning lacks practice, and it cannot be practiced at any time.

2. Prosthesis exercises:

Disadvantages: high cost (hundreds of thousands to several million), easy to damage, limited parts (usually the prosthesis has a single part, and the price of the whole body prosthesis is very expensive).

3. The present invention applies virtual X-ray photography room simulation exercises:

Advantages: It can be practiced at any time, does not increase the patient's dose, does not need to occupy the photography room, and there is no radiation problem.

The purpose of the present invention is to provide a system that uses virtual reality to simulate an X-ray studio.

To achieve the above objective, the present invention includes a virtual reality display and a control handle, wherein the virtual reality display includes a virtual reality (Virtual Reality, VR.) scene module and an object module, wherein , The virtual reality scene module stores the scene of the X-ray studio, the scene is displayed through the virtual reality display, the object module stores a number of objects used in the scene, and the object includes an inspection table and an X-ray machine, number of light field adjustment buttons, a virtual patient, an X-ray image, the object is displayed through the virtual reality display, wherein the X-ray image is coordinated with the examination table, the X-ray machine, and the light field adjustment The control handle is connected to the virtual reality display, and the control handle has a digital control unit for controlling and adjusting the examination table, an X-ray machine, a number of light field adjustment buttons, and a virtual For the patient, the control handle has a confirmation button for displaying the X-ray image on the virtual reality display.

By constructing a virtual X-ray photography room in virtual reality, radiologists can move freely in space. By simulating scenes, radiological machinery, simulating patients, X-ray images, and allowing radiologists to simulate examinations, the radiologists can be less Error rate during operation; establish an interactive learning environment to improve the radiologist's spatial concept of human body structure, examination room and instrument operation, so that radiologists can reduce the re-exposure rate of patients in actual clinical practice and achieve better medical quality.
