Which ultrasound technique is considered best?

• A. Static technique
• B. Moving technique; slow overlapping circles or parallel stroking
• C. Rapid, jerky movements
• D. Pulsed with no movement

Answer: (B)

The best ultrasound technique is keeping the transducer moving across the treatment area, using slow overlapping circles or parallel strokes. Moving the head distributes energy evenly and prevents concentrating heat in one spot, which reduces the risk of hot spots or burns and promotes uniform tissue heating.

This approach ensures you cover the entire target area with consistent exposure, which is safer and more effective than staying in one spot. A static technique can create hotspots; rapid, jerky movements produce uneven exposure and discomfort; and pulsing with no movement still confines energy to a small area, giving uneven heating and poor coverage.
