Abstract
Medical fluoroscopy is a set of radiological procedures used in medical imaging for functional and dynamic studies of digestive system. Major components in the imaging chain include image intensifier that converts x-ray information into an intensity pattern on its output screen and a CCTV camera that converts the output screen intensity pattern into video information to be displayed on a TV monitor. To properly respond to such a wide dynamic range on a real-time basis, such as fluoroscopy procedure, are very challenging. Also, similar to all other medical imaging studies, detail resolution is of great importance. Without proper contrast, spatial resolution is compromised. The many inherent advantages of CCD make it a suitable choice for dynamic studies. Recently, CCD camera are introduced as the camera of choice for medical fluoroscopy imaging system. The objective of our project was to investigate a newly installed CCD fluoroscopy system in areas of contrast resolution, details, and radiation dose.
