The active layer of the imaging plate in which the image is stored.

Phosphor layer

100

During indirect DR, before photons are converted to an electric signal, they must first be converted to:

light

100
An eight bit word is called a:

byte

100

The law healthcare professionals abide by that ensures patient health information is kept confidential.

Health Insurance Portability and Accountability Act (HIPPA)
100

A three-dimensional pixel is called a:

voxel

200

To retrieve the latent image from the imaging plate, it must be exposed to:

a laser
200

This is the material of choice for use as a scintillator because of the way the crystals form needles or columns to direct the light. 

Cesium iodide (CsI)

200
If you increase this, you will increase the spatial resolution.

Matrix size or fill factor

200

A networked group of computers, servers, and archives that can manage images in an electronic form.

Picture Archiving and Communication System (PACS)

200

This is what DICOM stands for:

Digital Imaging and Communication in Medicine

300

A line-by-line pattern of reading by a laser is called a:

Raster pattern

300

The photo conductor used in direct conversion digital radiography to convert photons directly to an electrical signal.

Amorphous Selenium

300

A graph that is generated by dividing a scanned area into pixels and determining the signal intensity for each pixel is called a:

histogram

300
This was established to provide a universal, standardized public format and protocol for communicating biomedical imaging files.

Digital Imaging and Communications in Medicine (DICOM)

300

This term determines the number of gray levels on a radiographic image.

bit depth

400

The device within the CR reader that detects the light emitted from the plate after laser reading is called:

Photomultiplier tube

400
What do both direct conversion and indirect conversion DR have in common?

TFT array that converts an electrical signal to a digital signal

400

Window level changes the level of:

brightness

400

Unnecessary increase of exposure to produce a quality image

Dose creep

400

A type of noise created on an image from an insufficient quantity of photons from improperly set mAs or kVp.

quantum mottle noise

500

The process of freeing trapped electrons from the imaging plate using a finely focused red laser is called:

Photostimulated Luminescence

500

In digital radiography, thin-film-transistors (TFTs) and charged coupled devices (CCDs) both have this in common.

They both collect and store the electrical charge which is then released to the ADC.

500

A type of local processing that amplifies or deletes all except the high frequencies for edge-enhancement and sharpness is called:

High-pass filtering

500

The size of an image file for a radiograph with a matrix of 512 X 512 with a 16-bit depth.

524,288 bytes or 524.288 kB

500

A measure of sensitivity and accuracy by which the image receptor converts incoming data to the viewing device.

Detective Quantum Efficiency (DQE)
