Heart disease diagnosis using medical imaging

Medical imaging comprises of variety of technique used to scan and take images of various parts of human body. The purpose is clinical and diagnostic in nature. Medical imaging is by and large a part of biological imaging and is often used research and in studies besides diagnosis

Medical imagery incorporates various discipline of science like nuclear, radiology, photography endoscopy and microscopy. In clinics radiology is used most often by expert radiologists. Hence in broader sense imaging for purpose is a sub discipline of medical engineering and medicine. 

The primary benefits are safety, cost and better diagnostic. Medical imaging plays an important role in this method of treatment and diagnosis. It assists non surgical disease diagnosis and hence treatment.         

The developments in the field of imagery for clinical and medical purposes have changed the entire paradigm of disease management. With further development in health sciences non invasive cardiology is becoming popular. The techniques find extensive use in heart disease treatment especially for diagnosing blocked arteries and other heart blockages.

Though these techniques are mostly non invasive but do incorporate invasive technique where ever necessary. Angiography is one such example of fluoroscopy where catheter guidance is required. Though purely applicable to cardiology, neuroscience and psychology medical imaging finds application in industries and scientific research.

In case of cardiology these techniques are used in coronary angiography and 3 D angio-cardiography. While in case of angiography, diagnosis is an invasive technique, the latter is non invasive process. In case of 3 D angio-cardiography data acquisition is carried out using and machine. The next step is DSP or digital signal processing along with VAD or Vertical acceleration detector to record blood flow pattern during various stages of heart function or cardiac cycles. Thus various data accumulated by this method is used to determine blockages with application of cartography.

Diagnosing heart disease has become safer due to non interventional processes. This is useful in angina pain treatment by detecting blood flow in the heart muscles and blockages. Non surgical procedures in case of heart treatment are being looked into with great hope.
