When sound hits a boundary between two media of the same propagation speed at oblique incidence: correct answers no refraction will occur. Refraction requires the oblique incidence of sound across a boundary between two media with different propagation speeds. As transducer frequency increases: correct answers axial and lateral resolution will increase Blood flow volume changes in the body are mainly controlled by what two factors? correct answers cardiac function and peripheral resista...

Which type of transducer has the smallest field of view in the near field? - Correct Answer sector Sector transducers produce a triangle shaped image and the FOV in the near field is very minimal compared to the other types of transducers The crystal in the ultrasound transducer converts: - Correct Answer electrical energy into mechanical energy Electrical pulses are applied to the crystal causing the production of mechanical vibrations. The crystal also processes the returning mechan...
