Coloured 3D computed tomography (CT) scan of a heart with enlarged coronary arteries. These vessels supply oxygenated blood directly to the heart muscle. The swollen arteries may have resulted from a blockage within the vessel, which can cause angina, or a symptom of high blood pressure (hypertension). This image sequence was produced using a multi-slice CT scanner, which uses a thin X-ray beam to scan around the patient to collect image slices, which can be combined to give a 3D model. A contrast agent, injected into the blood stream, allows the CT scanner to detect the blood vessels. Originally captured at 10 frames per second. | |
