X-ray Dose Reduction through Adaptive Exposure in Fluoroscopic Imaging
Published on: September 11, 2011
Abstract:
It is important for an imaging administrator to know a few things about XR 29, the new radiation standard for CT: what the standard means, how to assess existing CT equipment for compliance, and what will be lost in the case of noncompliance. On January 1, 2016 Medicare will pay 5% less for diagnostic CT scans performed on non-compliant CT equipment. In 2017, this reduction will soar to a 15% reduction in reimbursement Understanding what the XR-29 standard is and how to assess existing equipment will help protect the organization's bottom line, but it will also help keep patient radiation exposure to the lowest practical levels.

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...

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

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...
