Ultrasound technicians (sometimes called sonographers) are a special type of radiographer. Most ultrasound technicians train as a radiographer first and then go on to complete specialised training in sonography (ultrasound techniques).
Ultrasound technicians produce ultrasound scans which are used in the diagnosis or the treatment of a patient.
Ultrasound scans are useful because they give a real-time image of what it going on in the patient’s body (which looks a bit like a film on a television screen). This means that health professionals can use the ultrasound scan to see what is happening as they carry out procedures (such as egg collection during IVF treatment). The ultrasound technician is the person who controls the ultrasound so this can work.
