Question 1
Describe, with the aid of diagrams, a typical diagnostic ultrasound signal, including i) spectral content, ii) pressure amplitude and iii) wave shape. Explain what is meant by fractional bandwidth and discuss the advantages of large bandwidth ultrasound transducers. What is meant by the terms acoustic impedance? Calculate the acoustic impedance of a tissue with density 1.1 gcm-1, if the speed of sound in this tissue is 1540 ms-1. Explain why the specific properties of bone and air can cause difficulties for ultrasound imaging and provide clinically relevant examples.
Discuss why there is such a wide variety of transducer designs on the market? What transducer specifications would you consider important for (i) paediatric cardiac imaging and (ii) ultrasound guided prostate biopsy, and explain your choice
