Summary
A single radiation monitoring badge for fluoroscopy users may offer administrative savings. While yielding higher dose estimates, it minimally impacts radiation safety notifications, primarily due to eye dose dominance.
Area of Science:
- Medical Physics
- Occupational Health
- Radiology
Background:
- Interventional radiologists traditionally use two radiation monitoring badges.
- Assessing radiation dose is crucial for occupational safety in medical imaging.
Purpose of the Study:
- To compare a single-badge system against a two-badge system for monitoring radiation dose in fluoroscopy users.
- To evaluate the impact of a simplified monitoring system on administrative burden and safety compliance.
Main Methods:
- Analysis of 10-year historical radiation dose data from 114,500 individual measurements.
- Comparison of effective dose equivalent (EDE) from a two-badge system (collar and chest/waist) versus a single collar badge.
- Evaluation against established 'as low as (is) reasonably achievable' (ALARA) notification thresholds.
Main Results:
- Single-badge system EDE calculations were, on average, 2.7 times higher than the two-badge system.
- A slight increase in ALARA notification frequency was observed with the single-badge system.
- Notification frequency increase was minimal due to the dominance of lens of the eye dose.
Conclusions:
- A single-badge system may provide significant administrative and cost savings.
- Despite less accurate dose estimation, the impact on ALARA notifications is minimal.
- Potential benefits include reduced badge handling and fewer notifications from improperly worn badges.

362
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...

957
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
