B ultrasonic auxiliary teaching system and method based on augmented reality technology

Abstract

The invention relates to a B-ultrasonic auxiliary teaching system and method based on the augmented reality technology, and the system comprises an environment collection unit, a physical object recognition and positioning unit, a virtual scene generation unit, a virtual B-ultrasonic image generation unit, and a virtual scene display unit. The environment collection unit is used for acquiring environment data around a trainer; the physical object identification and positioning unit is used for identifying a physical object in a surrounding physical environment, positioning the position of the physical object in the surrounding physical environment and transmitting the position to the virtual scene generation unit; the virtual scene generation unit generates an initial virtual scene, converts a physical object into a virtual object, maps the virtual object to a corresponding position of the virtual scene, and transmits a relative position of the virtual object and a virtual patient to the virtual B ultrasonic image generation unit. The invention has the beneficial effects that a simulation environment does not need to be established by special hardware, and the cost is relatively low.

Description

technical field [0001] The invention relates to the fields of virtual reality and medical ultrasound, in particular to a B-ultrasound auxiliary teaching system based on augmented reality technology. Background technique [0002] Ultrasound is currently widely used in medical diagnosis due to its non-invasive and radiation-free characteristics. It usually takes several years to train qualified B-ultrasound doctors. The reason is that, firstly, B-ultrasound images rely on manual production by doctors, and obtaining clear and stable B-ultrasound images and correct reading requires long-term experience accumulation; secondly, the accumulation of doctors’ clinical experience depends on the number of cases and types of diseases It may take a long time to obtain clinical images of some rare diseases, and for small and medium-sized hospitals, the waiting time is even longer. [0003] In order to solve the above problems, B-ultrasound simulation came into being. In order to improv...

Problems solved by technology

In order to improve usability, the existing AR / VR-based B-ultrasound simulation system requires special hardware (such as human body models and probes) to establish a simulation environment, which is relatively expensive, lacks interaction with patients, and has a low degree of immersion
