Radiation protection in computed tomography (CT)
Computed tomography (CT) is a method that extends the clinical capabilities of X-ray imaging. Its high contrast sensitivity visualizes soft tissues and produces tomographic (slice) and three-dimensional (3D) volumetric images.
CT can be used for a wide range of clinical applications including several procedures for evaluating heart disease. With the help of CT, it is possible to optimize images for a wide range of anatomical sites and visualization of pathologic conditions. This is achieved by adjusting the relatively large number of exposure parameters in the examination protocol factors to produce the required visibility of the clinical condition that is being evaluated.
