Chapter 2: Q77PP (page 543)

If the deepest structure you wish to image is $10.0 cm$ from the transducer, what is the maximum number of pulses per second that can be emitted? (a) $3850$ ; (b) $7700$ ; (c) $15400$ ; (d) $1, 000, 000$ .

Short Answer

Expert verified

The correct answer is (b) $7700 s^{- 1}$ .

Step by step solution

Given data

Distance of object from transducer is $10 c m$ .

The Frequency

The number of pulses generated every second, is called frequency. Which is given as $f = \frac{1}{t}$

Here, t is the time period of a pulse.

Number Of Pulses Per Second

The pulses travel distance $10 c m$ then back to the transducer due to the reflection, so the total distance is $d = 20 c m$ . We are given the velocity through the tissue by $v = 1540 m / s$ .

$\begin{matrix} f = \frac{1}{t} \\ = \frac{v}{d} \end{matrix}$

Plug the values for $v$ and $d$ to get $f$ -

$\begin{matrix} f = \frac{1520 m/s}{0.20 m} \\ = 7700 s^{- 1} \end{matrix}$

Therefore, the maximum number of pulses is $7700 s^{- 1}$ .
