Abstract
An ultrasound therapy system with automatic dose control includes an ultrasound transducer, an ultrasound generator controllable in frequency and power output connected to the transducer, a system controller interfaced to the generator, input switches interfaced to the controller to enable the input of selected ultrasound treatment parameters, and a display interfaced to the controller. The controller is programmed to calculate an ultrasound treatment dosage in terms of frequency, ultrasound intensity, and treatment time from the entered treatment parameters. Once treatment is started, the controller tracks the accumulated dosage applied to the tissue. The clinician can vary the intensity or treatment time, and the controller will recalculate the other factor for the remaining portion of the unapplied treatment dosage.
