SID was too great.

grid failed to move during the exposure.

x-ray tube was angled in the direction of the lead strips.

CR was off-center.

If the quantity of black metallic silver on a particular x-ray film is such that it allows 1% of the illuminator light to pass through the film, that film has a density of

0.1

1.0

2.0

3.0

_______ occurs when an intensifying screen absorbs x-ray photon energy, emits light, and thenceases to emit light as soon as the energizing source ceases.

________ occurs when an intensifying screen absorbs x-ray photon energy, emits light, and continues to emit light for a short time after the energizing source ceases.

______ is the freckle-like appearance on some radiographs made using a very fast imaging system. The brightness of a fluoroscopic image is amplified throughimage intensification.

Recorded detail is unaffected by changes in ___

As the exposed film enters the processor from the feed tray, it first enters the _______ section

the developer section is where exposed _________crystals are reduced to black metallic silver.

Put theses in correct order
wash section
dryer section
the processor
the fixer

the processor

IRs/cassettes frequently have a lead-foil layer behind the rear screen that functions to

The term windowing describes the practice of

B
changing the image contrast and/or density

A graphic diagram of signal values representing various densities within the part being imaged is called a

Unopened boxes of radiographic film should be stored away from radiation and

B
in the vertical position

where the unexposed silver grains are removed from the film by the clearing agent.

Base-plus fog is a result of

the manufacturing process

1 only

1 and 2 only

1 and 3 only

1, 2, and 3

Every film emulsion has a particular base-plus fog, which should not exceed ____

_____ also called deflector plates, serve to keep the film on its proper course by directing or guiding it around corners.

The _______ are located at the top of the processor, out of the solution, and direct the film from one solution tank to the next.

An important feature of the pixel in a flat-panel TFT digital detector active matrix array is the:

The _____ (B) is defined as the ratio of the sensing area of the pixel to the area of the pixel itself. The sensing area of the pixel receives the data from the layer above it, which captures X-rays that are subsequently converted to light (indirect flat-panel detectors) or electrical charges (direct flat-panel detectors)

During measurement of blood pressure, which of the following occurs as the radiographer controls arterial tension with the sphygmomanometer?

B
The brachial artery is temporarily collapsed.

In digital imaging, the maximum spatial resolution is equal to:

The Nyquist frequency, which is 1/2X the pixel pitch (mm)

The wavelength of the detector system’s analog-to-digital convertor’s electrical signal

The distance between the silver halide crystals in the image receptor

The detective quantum efficiency of the imaging system; this should be at least 2X the frequency of the analog-to-digital convertor electrical signal
