Lateral resolution (ultrasound)
Lateral resolution in ultrasound refers to the ability to discern to separate objects that are lateral to each other. Lateral resolution is roughly four times worse than axial resolution in ultrasound. It is primarily determined by the beam width of the ultrasound beam.
Strategies to improve lateral resolution using the highest number of lines per frame and setting multiple focal depths. However, these may adversely affect the temporal resolution of the image by reducing the frame rate.
