X-ray Dose Reduction through Adaptive Exposure in Fluoroscopic Imaging
Published on: September 11, 2011
Abstract:
The Food and Drug Administration (FDA) is issuing a final rule on the Federal performance standard for diagnostic X-ray systems and their major components (the performance standard). Experience gained by FDA in administering the performance standard has shown the need for making these changes to clarify and simplify the performance standard, reduce the regulatory burden on affected manufacturers (without compromising the public health), and generally improve the effectiveness of FDA's regulation of diagnostic X-ray equipment. Elsewhere in this issue of the Federal Register, FDA is proposing to amend this final rule to revise limits on the maximum patient entrance exposure rate for fluoroscopy systems in the high-level control mode and other modes of operation.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
