Please provide clear and detailed answer. Will rate.

1. You are imaging through the following: Fat (1 cm) Tissue that is similar to water Liver (5 cm) transducer For the questions below, you need to take into account both the reflection of off each boundary, as well as the attenuation through each type of tissue. Values for Z and a are given in my ppt slides in "table 10.1". Assume the ultrasound wave entering the fat from the ultrasound transducer has pressure Po 500 kPa, and that the pulse is transmitted at time to 0, and the frequency is 3 MHz. Determine the pressure amplitude P for the echo that is received off of the fat/liver boundary. Determine the time t that the echo is received. (4 pts) Determine the pressure amplitude P for the echo that is received off of the liver/water boundary. Determine the time t that the echo is received. (4 pts) a. b.

Explanation / Answer

1. pressure amplitude received for the echo received off by fat/liver boundary is

=density*g*h

Time =2seconds

2 pressure amplitude received for the echo received off by liver/water boundary is

= density*g*h

time= 5 seconds
