Increasing the number of focal zones will improve lateral resolution. Lateral resolution is the ability to distinguish two structures that are close together side by side. By increasing the number of focal zones, the sound beam can be focused at different depths along the scan line, leading to better lateral resolution. This allows for improved clarity and sharpness in the imaging of structures in the lateral direction. Conversely, decreasing the scanning depth (Option A), maximizing the output power (Option C), or using a lower frequency (Option D) are not directly related to improving lateral resolution.
