SPI ULTRASOUND REGISTRY REVIEW Questions and Answers (100% Pass) 2025

The layer of material within the transducer which has an intermediate impedance between the transducer element and the human tissue in known as the: - ️️matching layer Huygen's Principle - ️️states that waves are the result of the interference of many wavelets produced at the face of the transducer What happened to intensity if the amplitude of a signal is halve? - ️️Quarted/ Intensity is proportional to the amplitude squared, so if the amplitude is halved, the resulting in...
