Which statement best describes the near field in ultrasound therapy?

Explanation:
The near field is the region closest to the transducer where the ultrasound beam is still developing and tends to be nonuniform in intensity. In therapy, this energy is harnessed to heat tissues and produce mechanical effects, making the near field a practical zone for delivering therapeutic ultrasound. Because the beam is not uniform there, you’ll see varying intensity patterns, but that doesn’t negate its clinical use. So the best statement is that the near field is used for therapeutic purposes. The other options misstate its clinical role or its beam characteristics.
