Ultrasound is a technique for searching for tissues within the body by using high frequency sound waves.
We are all more familiar with its use of monitoring human pregnancies
These sound waves are then collected and the computer can then give us information to help aid diagnosis
We use ultrasound for a variety of purposes among them pregnancy diagnosis, investigation of bladder problems and heart disease.
Patients may be sedated but rarely anaesthetised, as it is not so vital for them to keep still.
