Question 1 = - Answers✔Histogram
Histogram - Answers✔A graphic representation of a digital image, assigns values
in reference to PSP image capture, to release the latent image, which of the following devices is
scanned over the phosphor plate?
-photomultiplier tube
-fluorescent light
-focused laser light
-lithium crystal - Answers✔Focused laser light
The acronym RIS stands for - Answers✔Radiology Information System
Process of joining two or more images into one continuous image is known as image -
Answers✔stitching
Window width - Answers✔controls contrast
Which of the following best describes the sequence for PSP image capture - Answers✔Phosphor
plate, focused laser light scanner, photomultiplier, analog-digital converter, review station
The more light spread, the _______ the MTF - Answers✔lower
image matrix - Answers✔Consists of pixels arranged into rows and columns
Pixel - Answers✔short for "picture element", the fundamental unit of a digital image, typically a
tiny square or dot that contains a single point of color of a larger image.
Dot pitch - Answers✔The amount of space between pixels, which affects the display quality of
images shown on a monitor.
Resolution - Answers✔number of pixels contained on a display

Modulation Transfer Function (MTF) - Answers✔The ability of a system to record available
spatial frequencies
Image acquisition is tested through the use of - Answers✔Phantoms
Thin client computer - Answers✔a device that requests services and resources from a server:
could be another computer or printer; not enough power to run multiple systems
Device used to measure luminescence of areas on the monitor - Answers✔photometer
Which of the following information might be found in the DICOM header of an image?
1. Patient name
2. Laboratory test results
3. Ordering physician - Answers✔Patient name and ordering physician
Local area network (LAN) - Answers✔is a small area networked with a series of cables or
wireless access points that allow computers to share information and devices on the same
network
Wide area network (WAN) - Answers✔is a network that spans a large area: city, nation,
continent, or the world. It is used to connect computers that are not physically attached
Windowing - Answers✔the process of selecting some segment of the total pixel value range (the
wide dynamic range of the receptors) and then displaying the pixel values within that segment
over the full brightness (shades of gray) range from white to black.
Leveling - Answers✔manipulations of the screen image and are not adding or subtracting
radiation exposure to the patient
Shuttering - Answers✔used to blacken out the white collimation borders in a digital image,
effectively eliminating veil glare.
Collimation - Answers✔The restriction of the size and shape of the x-ray beam in order to
reduce patient exposure.
Purpose of a personal repeat log is to - Answers✔Establish error trends
veiling glare - Answers✔Loss of contrast in an image-intensifier tube because of internal scatter
of radiation in the form of x-rays, electrons, and particularly light is called veiling glare.
Thick client computer - Answers✔a computer that can work independently of the network and
process and manage its own files
In a digital radiography system, which of the following are needed to produce a radiographic
image?
