The development of the first head CT scanner was successfully developed by Hounsfield engineers at EMI in 1971. The success of CT became a major breakthrough in the history of the medical profession and Housfield was awarded the Nobel Prize for Medical Biology in 1979 for his outstanding contributions in the field of radiology. CVR, VR, MPR, SSD and a series of analysis software, which can observe the coronary arteries from multiple angles and also extract the blood vessels individually to straighten and dissect them for analysis. Its accuracy rate is extremely high and it can detect plaques larger than 0.5mm, and the patient does not need to be hospitalized, and the examination is safe, non-traumatic and without side effects. The birth of 64-row CT has fought the battle of coronary heart disease blocking, making the diagnosis of coronary heart disease no longer difficult. In addition, 64-row CT can accurately diagnose a series of heart diseases such as valvular disease, precordial disease, myocardial bridge, opening variation, vascular tortuosity, coronary artery aneurysm, etc., distinguishing these lesions from coronary heart disease and avoiding a large number of misdiagnosis, which has become the most reliable and the first examination method to diagnose coronary heart disease.
