Computer Receiver A lot of technology is involved in the different parts Transducer of the ultrasound technique. Let us shortly mention that the transducer, that trans- mits and receives the ultrasound energy into and from the body is a key component. It is built up of hundreds of transducers in order to take a high reso- The main components of ultrasound lution real-time scan. The many transducers create a wavefront and the angle of the wavefront can be altered by fring the transducers one after another. By changing the angle of the wavefront, a three-dimensional image can be built up over a large area. Doppler ultrasound The velocity of the blood can be measured by the Doppler effect i. Side effects Current evidence indicates that diagnostic ultrasound is safe even when used to visualize the embryo or fetus. In this connection we would like to mention that research in the beginning of 1980s showed that use of clinical ultrasound equipment could result in water radicals (H. Furthermore, in work with cells in culture exposed to ultrasound resulted in damage (simi- lar to those known from ionizing ra- diation). In the fgure to the right is given the world average use of radiation for medical imag- ing. New techniques and methods have been added with the result that the total dose (the collective dose) has increased. Since the 1950s it has been a goal to keep the doses for each examination as low as pos- sible in order to prevent any deleterious ef- fects of radiation.
