Example Embodiment

[0027] Example 1

[0028] In this embodiment, the structure of the transesophageal ultrasound visualization simulation system is as follows figure 1 As shown, it includes an intelligent phantom 1, a cardiac ultrasound image simulation acquisition device 3, a computer 7 connected to the cardiac ultrasound image simulation acquisition device, a transesophageal ultrasound probe posture data acquisition device 2 and a sensor 6.

[0029] The smart phantom 1 includes a phantom and a three-dimensional simulated heart 4, a simulated esophagus, and a stomach 5 set in the phantom. The head and chest of the smart phantom are all made of transparent plastic, and the mouth of the head can be moved and can be opened and closed. , The head and neck can be separated, which can ensure the placement and disassembly of the transesophageal ultrasound probe posture data acquisition device and sensor. You can directly see the realistic organ structure in the esophagus and chest cavity, and you can see th...

Example Embodiment

[0036] Example 2

[0037] This embodiment uses the transesophageal cardiac ultrasound visualization simulation system described in Example 1 to further illustrate the transesophageal cardiac ultrasound visualization simulation method. In this embodiment, the steps of the transesophageal cardiac ultrasound visualization simulation method are as follows:

[0038] The first step is to use the probe of the cardiac ultrasound image acquisition device and the transesophageal ultrasound probe posture data acquisition device 2 to synchronously obtain the probe posture data of the transesophageal echocardiogram and the cardiac ultrasound image acquisition device in real time, and collect the acquired cardiac ultrasound images Establish a one-to-one correspondence between the probe posture data of the device and the transesophageal echocardiogram and store it in the database of the computer 7;

[0039] The second step is to build a standard virtual composite heart model (this model is realize...

Abstract

The invention discloses a transesophageal echocardiography visual simulation system, comprising an intelligent phantom, a heart ultrasonic image stimulation and acquisition device, a computer connected with the heart ultrasonic image stimulation and acquisition device and a transesophageal ultrasonic probe attitude data acquisition device, wherein, the heart ultrasonic image stimulation and acquisition device is used for stimulating and acquiring heart ultrasonic images, and transmitting the acquired heart ultrasonic images to the computer; when the heat ultrasonic image stimulation and acquisition device acquires the heart ultrasonic images, the transesophageal echocardiography probe attitude data acquisition device and a sensor are used for synchronously acquiring probe attitude data of the heat ultrasonic image stimulation and acquisition device, and transmitting the acquired probe attitude data to the computer; and the computer is used for analyzing, processing and visually displaying the received heart ultrasonic images and the probe attitude data.

Description

technical field [0001] The invention belongs to the technical fields of medical image analysis and processing and virtual simulation, and in particular relates to a visual simulation system and method for transesophageal echocardiography teaching and training and computer-aided surgery. Background technique [0002] Ultrasound diagnosis of heart disease has always been the focus and difficulty in the field of ultrasound diagnosis. Transesophageal echocardiography is a new development in the field of cardiovascular disease diagnosis and monitoring, and provides a new means for the diagnosis of various heart diseases and large vessel diseases. The structure and movement of the heart are very complex, which puts higher demands on the examiner's spatial thinking ability and clinical thinking ability. Therefore, it is very important for doctors to quickly master echocardiography through high-quality training. There are many doctors and students at home and abroad who are in urgen...
