Question 1

Which adjustment will reduce the artifact in the cystic lesion in image A resulting in image B?  

  1. Option A:
    Turn off harmonics
  2. Option B:
    Increase dynamic range
  3. Option C:
    Turn on edge enhancement
Show answer and explanation

Correct answer: C

In image A, the borders of the cystic lesion might appear less defined due to a lack of edge enhancement. By turning on edge enhancement, the ultrasound system processes the image to accentuate the boundaries, leading to a clearer and more distinct outline of the cystic lesion as seen in image B. This adjustment reduces the artifact within the cystic lesion by emphasizing the differences in the adjacent tissue interfaces, thus improving the overall image quality.

Question 2

Which target group is used to evaluate transverse distance measurement accuracy in this tissue- mimicking phantom image?


  1. Option A:
     Option A
  2. Option B:
    Option B
  3. Option C:
    Option C
  4. Option D:
    Option D 
Show answer and explanation

Correct answer: D

In the tissue-mimicking phantom image, Option D (blue box) is used to evaluate transverse distance measurement accuracy. Phantoms are used to simulate human tissue and provide a standardized way to test the accuracy and precision of ultrasound machines. Transverse distance measurement  accuracy is assessed by measuring known distances between targets in the phantom. The blue box (Option D) typically contains targets positioned to specifically test the accuracy of transverse measurements, ensuring that the ultrasound system provides reliable and precise distance readings.
