SPI Ultrasound Physics Review Exam - Questions and Answers Relates to likelihood of harmful bio effects from cavitation Mechanical index Predicts maximum temperature increase Thermal index Measures output intensity of the beam Hydrophone Region of increased brightness due to higher intensities in focal zone Focal banding Occurs when sound travels through a medium with a lower attenuation rate than the surrounding tissue Enhancement Beam travels through an area of high attenuation Shadowing Bea...

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 r...
