Abstract
An ultrasonic therapeutic device and an ultrasonic therapeutic system including the ultrasonic therapeutic device and guided by an imaging device are provided. The ultrasonic therapeutic device includes an ultrasonic therapeutic applicator that comprises an ultrasonic transducer, a box which contains the ultrasonic therapeutic applicator and the couplant liquid, a moving unit which extends through the wall of the box and connects the ultrasonic therapeutic applicator, and compensating units which set on opposing sides of and incorporate with the box and holds the level of the liquid when the moving unit drives the ultrasonic therapeutic applicator to move. Stabilization of the liquid level in the box consequently decreases the interference to imaging results of an imaging device due to the level changing of the couplant liquid and improves the diagnostic accuracy of the imaging device.
