(a) The principle of the ultrasound testing in BHM; (a) FPI fiber-optic ultrasonic sensor; (b) Response of the sensor under 27.73 Pa acoustic excitation in frequency-domain; (c) Signal intensity ...

This video shows the operating principle of PILine ultrasonic piezomotors. The piezoceramic actuator forms an integral part of ultrasonic piezomotor. The actuator is excited to ultrasonic vibrations ...

The brain is never completely at rest. Even without external input, it produces spontaneous neural activity that creates synchronized fluctuations across different regions - a process known as ...

Ultrafast functional Doppler ultrasound (fUS) is based on the principles of conventional Doppler ultrasonography but operates at an extremely fast frame rate. This significantly improves ...

Sonograms and ultrasounds are closely related but refer to different things. An ultrasound is an imaging tool that produces a sonogram. Often, the terms sonogram and ultrasound are used ...
