Final answer:
The lateral resolution of an ultrasound is determined by the wavelength of the ultrasound waves being used. Smaller wavelength results in better resolution. The formula to calculate the lateral resolution is wavelength / 2.
Step-by-step explanation:
The lateral resolution of an ultrasound is determined by the wavelength of the ultrasound waves being used. The smaller the wavelength, the better the resolution. To determine the lateral resolution, we can use the formula:
Lateral resolution = wavelength / 2
For example, if the wavelength of the ultrasound waves is 0.1 cm, the lateral resolution would be 0.05 cm.
