MODEL RELEASED. Doppler echocardiography test. Nurse using an ultrasound scanner to carry out a doppler echocardiography test on a patient in a hospital's cardiology department. The scanner uses ultrasound and the Dopppler effect to allow examination of a patient's heart and blood flow. Ultrasound scans use high-frequency sound waves emitted by the scanner and reflected from within the body to build up a picture of internal structures. Photographed in the UK | |
