Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...

Area of Science:

Medical Imaging
Radiology
Radiation Safety

Background:

CT radiation dose management is gaining importance due to new CMS measures.
Significant global variation in CT radiation dose indicates limitations in current optimization techniques.

Purpose of the Study:

To propose a strategy for facilitating global CT radiation dose optimization.
To define CT radiation dose optimization as routine use of parameters yielding images just above acceptable quality thresholds, considering patient characteristics and scanner efficiency.

Main Methods:

Establishing image quality-based target doses for every protocol, varying with patient size for non-head CT.
Implementing a process control program involving measurement, evaluation, feedback, and control.
Engaging local teams of radiologists, physicists, and technologists with necessary tools and support.

Main Results:

The proposed strategy aims to reduce variation in CT outcomes and allow for decreased dose targets.
A process control program is essential for maintaining CT radiation dose optimization.

Conclusions:

Coordinated efforts involving multiple stakeholders (researchers, industry, regulators, payers, ACR) are critical.
Adopting a structured, team-based approach, similar to other industries, can achieve universal CT radiation dose optimization.
