Sample Ultrasound Physics Quiz

1. Which resolution is determined by frame rate?

Temporal resolution

Axial resolution

Spatial resolution

Lateral resolution

temporal resolution is directly related to frame rate

Explanation

temporal resolution is directly related to frame rate

2. Which system setting could increase the listening time and decrease temporal resolution?

Depth

Power

Amplification

Compression

power, amplification and compression have no effect on temporal resolution

Explanation

3.

Which resolution would be the most important when evaluating the heart with respect to motion?

Temporal

Axial

Spatial

Lateral

The most important resolution when evaluating the heart with respect to motion would be temporal resolution. Temporal resolution refers to the ability to capture and distinguish rapid changes over time. In the context of evaluating the heart, it is crucial to have high temporal resolution to accurately assess the motion and function of the heart. This allows for the detection of abnormalities such as arrhythmias or abnormal contractions that may not be visible with lower temporal resolution.
