Summary
New Jersey
Area of Science:
- Medical Physics
- Radiological Health
- Quality Assurance
Background:
- Traditional x-ray inspections focused on machine parameters.
- New Jersey shifted to outcome-based inspections in 1996.
- Stakeholder involvement emphasized quality assurance.
Purpose of the Study:
- To implement and evaluate an outcome-based quality assurance program for diagnostic x-ray facilities.
- To assess the impact of new regulations on image quality and patient exposure.
Main Methods:
- Implemented outcome-based inspections focusing on image quality and entrance skin exposure (ESE).
- Mandated quality assurance programs for all diagnostic x-ray facilities.
- Credentialed medical physicists to oversee quality assurance.
Main Results:
- Entrance Skin Exposure (ESE) reduced by 34% (lumbar spine), 46% (chest), and 66% (foot).
- Image quality improved by 22%.
- Quality improvement initiatives extended to the dental x-ray community.
Conclusions:
- Outcome-based inspections and quality assurance programs significantly improve diagnostic x-ray performance.
- Credentialed medical physicists are crucial for successful quality assurance implementation.
- The program effectively reduced patient radiation exposure while enhancing image quality.

X-ray Imaging
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 X-rays, and by 1900, X-ray was widely...
Imaging Studies for Cardiovascular System III: X-Ray
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...

Quality Assurance
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...
Radiological Investigation I: X-ray and CT
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...
Quality Control
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
