ISTILAH - ISTILAH di CR / DR

Brightness
Analogous to window level. The brightness of an image determines how
light or dark the overall image appears.
Contrast
Analogous to window width. The contrast defines the span of code values
and the relationship between the dark and light areas of the image.
CR
Computed Radiography. Based on storage phosphor plates.




DICOM
Digital Imaging and Communication in Medicine. A standard communication format that allows different types of equipment to work together when connected to a network.
DLR
Digital Luminescence Radiography
DQE
Detective Quantum Efficiency
DR
Direct Radiography or Digital Radiography (based on a large area flat panel or CCD)
• direct-conversion flat panel detectors based on amorphous selenium
• indirect-conversion flat panel detectors based on amorphous silicon
• indirect-conversion based on charge-coupled device (CCD) detectors
Dry Laser
Laser camera, where the use of a film
Camera
processing unit and of chemicals is not required. Laser light is exposed to film and after a thermographic process images are fixed on film.
Dynamic
Exposure range in which data can
Range
be used to get acceptable image
quality.
Exam
A set of images, usually of the same body part, which are part of the procedure and have a common accession number.
Gen Rad
General Radiology
GP
General Purpose
Grid
Is used in cassettes to reduce scattered radiation and to increase sharpness.
HIS
Hospital Information System
Histogram
Graphical display of the distribution of grey levels.
HR
High Resolution
Hub
A network device that allows one or more devices to be interconnected to a network backbone.

IT
Information Technology
LAT
Lateral Exposure
Latent Image
An image which has been captured on a storage phosphor screen, but not digitized or processed. This is the image that the CR system extracts when it processes the cassette.
LUT
Look-Up Table. A set of values that can be mathematically applied to the digital image which alters the look of the image. The LUT is generated by the image processing algorithms of the
vendor.
MPPS
Modality Performed Procedure Step
Notification SOP Class
PA
Posteroanterior Exposure
PACS
Picture Archiving and Communication System
Pixel
Scanning point on plate or film.
QA-Workstation
Quality Assurance Workstation
QC-Workstation
Quality Control Workstation
Raw Image
An image that has been read from the phosphor screen and digitized but not yet processed.
RIS
Radiology Information System
SC

Worklist
A DICOM Modality Worklist enhances your workflow by importing patient demographics and study information
from an information management system. Using the worklist eliminates errors from manual entry, lets exams
begin on time, and assures the information is catalogued correctly when sent to a PACS broker
