What can you do to improve the temporal resolution while scanning?

• A. Increase Focal Zones
• B. Increase Depth
• C. Decrease Acoustic Scan Line Density
• D. Increase Sector Width

Answer: (C)

Temporal resolution is about how quickly successive images can be captured, i.e., the frame rate. To improve it, you want to reduce the amount of data collected per frame. Decreasing acoustic scan line density achieves this by using fewer scan lines to cover the same region, so the system can assemble each frame faster and you get a higher frame rate. The trade-off is that lateral resolution and image detail across the width may suffer because there are fewer samples to define the image. Increasing focal zones, increasing depth, or widening the sector all tend to require more data per frame or longer acquisition times, which lowers the frame rate and thus worsens temporal resolution.
