Computed Radiography (CR)
The CR reader unit scans the IP with a(n):
Laser
This type of DR detector converts x-ray energy directly into electrical charges.
Direct Detector
Most imaging monitors are this type of flat panel display.
Liquid Crystal Display (LCD) Screen
This system is responsible for image acquisition, display, networking, and storage.
PACS
The light field and radiation field must align within ± ____ % of the SID
2
The active portion(s) of a CR IP is (are):
Photostimulable Phosphor (PSP)
Unlike CR, DR uses this type of detector (wired or wireless) that communicates directly with the computer workstation.
Flat Panel Detector
When compared to a technologist workstation, monitors at the radiologist workstation are typically designed with _____ resolution.
Higher
This standardized protocol allows PACS and imaging modalities to communicate.
DICOM
This type of monitor tests ensures the observer sees consistent image contrast across the display.
Grayscale Standard Display Fucntion
In computed radiography, imaging plates (IP) can store the image for several hours; after that, the energy slowly dissipates, and the latent image fades; plates should be processed within _ hours.
8 hours
Which component of an indirect capture flat-panel detector converts incident x-ray photons into visible light photons?
Scintillation Layer
_________ is the measurement of luminance of an area of a radiographic image displayed on a monitor.
Brightness
This system is used for ordering procedures and reporting radiology result.
RIS (Radiology Information System)
The AEC detector calibration test should be accurate within ± ____%
