Production and use of ultrasound past paper questions
A2 Physics 9702 · Medical physics. 1 understand that a piezo-electric crystal changes shape when a p.d. is applied across it and that the crystal generates an e.m.f. when its shape changes 2 understand how ultrasound waves are generated and detected by a piezoelectric transducer 3 understand how the reflection of pulses of ultrasound at boundaries between tissues can be used to obtain diagnostic information about internal structures 4 define the specific acoustic impedance of a medium as Z = ρc, where c is the speed of sound in the medium 5 use IR / I0 = (Z1 – Z2)2 / (Z1 + Z2)2 for the intensity reflection coefficient of a boundary between two media 6 recall and use I = I0e–μx for the attenuation of ultrasound in matter
