Stanford University, the US prestigious university, recently revealed that it is developing a VR cardiac assistive treatment system developed by San Francisco-based software company Lightaus.
VR is not the first case to go into medicine. Stanford University is committed to heart disease.
The new VR system being developed at Stanford University not only clearly shows the movement of blood vessels on the surface and inside of the heart and around the heart, but also hideable lesions such as defects in the heart can be clearly distinguished.
Doctors and patients interact with each other and see what's wrong with their heart.
Although traditional CT, MRI, electrocardiogram, and other techniques are indispensable, today's more advanced VR technology will undoubtedly occupy an important part of heart disease treatment. Like high-risk surgery such as brain surgery, a more intuitive and accurate VR assist system is obviously more conducive to the success rate of surgery.
Pressure Transducer is a device or device that can sense Pressure signals and convert them into usable output electrical signals according to a certain law.Piezoresistive sensor is an ideal sensor for this purpose. For example, it is used to measure the airflow pressure distribution of the helicopter wing, test the dynamic distortion of the engine air inlet, the pulsating pressure of the cascade and the jitter of the wing. A specially designed silicon pressure sensor is used to measure the central pressure of jet engine, and its working temperature is above 500℃. A silicon pressure sensor with an accuracy of 0.05% is used in Boeing's atmospheric data measurement system. The piezoresistive sensors can be densely installed at the inlet of the wind tunnel and in the model of the engine inlet pipe in the model of the downsized wind tunnel model. The single sensor is only 2.36 mm in diameter and has a natural frequency of up to 300 KHZ, with nonlinearity and hysteresis of ±0.22% of the full range. In biomedicine, piezoresistive sensors are also ideal detection tools. The needle type piezoresistive pressure sensors and sensors which can measure pressure in cardiovascular, intracranial, urethra, uterus and eyeball have been made. Figure 3 is a schematic of a sensor used to measure brain pressure. Piezoresistive sensors are also used effectively in the measurement of explosion pressure and shock wave, vacuum measurement, monitoring and control of the performance of automotive engines, as well as in the measurement of weapons such as gun bore pressure, launch shock wave and other measurements. In addition, piezoresistive sensors are widely used in oil well pressure measurement, direction finding while drilling and detection of fault points of underground sealing cables, as well as flow and liquid level measurement. With the further development of microelectronics and computer, the applications of piezoresistive sensors will develop rapidly
