Question

You suspect a calcification is present within the left ventricle. You activate Harmonics and add a focal zone to the field of view. Which type of resolution will degrade with these changes?

A) Temporal
B) Lateral
C) Contrast
D) Axial

Answer 1

Using Harmonics and adding a focal zone when suspecting calcification in the left ventricle negatively affects temporal resolution because they require more processing time and reduce the frame rate. The correct option is A.

Step-by-step explanation:

When a calcification is suspected within the left ventricle, using Harmonics and adding a focal zone can affect the temporal resolution of the ultrasound imaging. Temporal resolution refers to the ability of the ultrasound system to accurately track moving structures in real-time.

By introducing Harmonics and adding a focal zone, the frame rate may decrease because these adjustments require more processing time, which can lead to a reduced ability to capture rapid motions within the heart, such as valve movements or wall motion during the cardiac cycle.
