AB  - Arteriosclerosis is a Coronary Artery Disease (CAD) that is caused due to the 
  deposition of plaque in the walls of arteries by which the arteries narrows 
  down (stenosis) and the blood flow gets restricted. Computed Topographic Angiography 
  (CTA) has been used in clinical diagnosis and it is very difficult to visualize 
  the blood vessels and the stenosis due to the presence of bones and tissues. 
  Moreover, the measurement of stenosis is important for stent employment which 
  improves the blood flow. In clinical practice, with modern imaging techniques, 
  visualization of stenosis and stents remains challenging and researchers go 
  to image processing techniques. This parchment focuses on three main strategies 
  to improve the image quality. First, blood vessel visualization is done by employing 
  a technique named Temporal Mask Time Mode Digital Subtraction Angiography (TMDSA). 
  This can effectively reduce the motion artefacts in angiographic images. Second, 
  the TMDSA image is further enhanced by image processing techniques such as histogram 
  equalization, thresholding, morphological and advanced morphological operations 
  for better visualization. Third, shape detection and measuring operations have 
  been developed for detection of stenosis and measurement of stenosis. The proposed 
  method have been evaluated on various CT angiography images qualitatively and 
  quantitatively.
