Answer :
Final answer:
The statement that 100 scan lines and a frame rate of 30 per second yields a transducer frequency of 3000 Hz is false. Transducer frequencies are typically much higher, in the MHz range, and depend on factors such as the speed of sound in the medium and imaging depth.
The correct answer is option b) False
Explanation:
If 100 scan lines make up an image and the frame rate is 30 per second, the transducer's frequency is not necessarily 3000 Hz. This statement is false because the frequency of the transducer depends on the speed of sound in the medium and the depth of imaging, not directly on the scan lines or frame rate. Specifically, in an ultrasound machine, the transducer frequency (often several MHz) is much higher than what can be calculated by simply multiplying the number of scan lines by the frame rate.
For diagnostic ultrasound applications, a common transducer frequency can be around 2 to 15 MHz, which is much greater than 3000 Hz. It's important to differentiate between the frequency of the sound waves produced by the transducer and the frame rate of the image being displayed, which are not directly proportional to each other in this context.
