Ultrasound therapy

Therapeutic ultrasound is one of the most common treatments used in the therapy of soft tissue

Ultrasound consists of inaudible high frequency mechanical vibrations created when a generator produces electrical energy that is converted to acoustic energy through mechanical deformation of a piezoelectric crystal located within the transducer. Since an ultrasound therapy device only transmits pulses, and unlike the ultrasound sonograph does not emit ultrasound signals, fewer channels are required in the front-end than in an ultrasound sonographic device. Usually a microcontroller controls the intensity and generates the pulses which are then forwarded to the output part (pulser, beamformer).


An ergometer is an instrument that measures the amount of work that is done by human muscles

It is a rowing machine that provides aerobic conditioning. The ergometer is best suited to people with problems such as chronic lower backs.One essential element of an ergometer is the electronically controlled eddy current brake with which the load can be varied. The overall control of the brake, load, etc., is handled by a microcontroller. Some ergometers offer additional functionality for analysis of the body in terms of body fat and water content, for which there is a special monolithic integrated front-end IC.

Electromagnetic therapy

Electromagnetic therapy involves the use of electromagnetic energy to diagnose or treat disease

In addition to the power unit, which generates the required AC power for the electromagnetic therapy, such a device also requires a microcontroller, sensors, a timer, and a circuit for controlling the intensity of the emitted power.
