You are performing a 3D sonogram and notice the volume rate is 8 Hz. What does this represent?

• A. Number of transmitted sound pulses per second
• B. Number of frames per volume
• C. Number of received pulses per minute
• D. Number of volumes displayed per second

Answer: (D)

In 3D ultrasound, the volume rate tells you how many complete 3D datasets are generated each second. An 8 Hz volume rate means eight volumes are produced per second, so you’re seeing motion more rapidly in 3D. Each volume is built from many 2D slices captured in quick succession, so increasing the volume rate improves temporal resolution of the 3D image but can involve trade-offs with spatial resolution or image quality depending on the system. This measure is not the rate of transmitted pulses per second, nor is it the number of frames per volume, nor the number of received pulses per minute. It specifically represents how many full 3D volumes are displayed each second.
