How Does an Ultrasound Machine Work? • Ultrasound

The ultrasound technician applies a mineral-oil-based ultrasound gel to the patient’s skin before doing an ultrasound scan. Ultrasonic waves do not travel well through air, and the gel allows sound waves to be transmitted from the probe through the gel directly to the patient’s skin. Linear probes produce high frequencies and generate high-resolution images but do not penetrate deeply into ...
