Question

What does the red dot on the probe help within the produced image?

(a) To check if the correct probe was used

(b) To check the probe orientation

(c) To check the depth of the probe that was used

(d) To check the plane of the image.

I had been asked this question by my college professor while I was bunking the class.

The doubt is from Ultrasound in chapter Diagnostic Investigation via Imaging Techniques of Clinical Science

Answer 1

Right option is (b) To check the probe orientation

Explanation: When the probe is being used, it can move in various ways but the image being formed is a horizontal image. Thus, the red dot at the head of the probe appears to the left of the image and helps in working out the orientation of the organ or the foetus.
