Exam 10: Quality Control for Digital Radiography

With integrated systems, the receptor needs to be re-exposed to a uniform field to detect the presence of debris.

____ manufacturers have developed a variety of phantoms and automated tests to assist us in assessing performance on a periodic basis.

The specific QC tests that are required for digital mammography are those specified by the imaging equipment manufacturer, with the exception of the limitation on maximum radiation dose, which is not more than that allowed for a ____.

Integrated systems have uniform surfaces to capture the radiographic projection, but the efficiency of collection of stimulated emissions is highly nonuniform across the field of view.

Since a key aspect of QA is a visual inspection of the DR image, it is important to consider the capabilities of the QC workstation where we are making decisions.

The one test that can and should be done for every DR image is a(n) ____________________ assessment of image quality before release.

At extremely high contrast, any DR image will appear ____________________.

____ is used by imaging scientists and engineers to mean the ratio between the highest detectable radiation level and the lowest detectable radiation level for an image receptor.

The value of the DR exposure indicator is usually visible at the QC ____________________.

What is another name for the flowchart of the steps involved in performing a DR exam?
