Exam 5: Flat-Panel Digital Radiography

A higher MTF value at ____________________ spatial frequencies means that the detector provides better contrast resolution.

The charge from each pixel in a row is transferred to the next row and subsequently down all the columns to the final ____________________ row.

The ____ is a graph of the contrast plotted as a function of spatial frequency.

While the low frequencies contain fine details of the image, high frequencies contain the contrast information in the image.

Which of the following is a photoconductor that conducts electrons when struck by light or X-ray photons?

Flaws in the various components that make up a panel can lead to image lag.

A system that has a higher spatial frequency at an MTF of 0.1 will show better spatial ____________________ than a system that has a lower spatial frequency at an MTF of 0.1.

____ produce(s)lateral spreading of light, which destroys the spatial resolution of the image.

With selenium drum technology, a negative charge is first placed on the drum, which is then exposed to X-rays.

Image processing is not intended to correct poor images due to routine errors that are made during image ____________________.
