RT202 MODULE 7 and 8 LONG EXAMINATION

Marie Sklodowska Curie

The development of mobile radiography is linked to

Magneto-Optical Disk

More reliable than some of the other long-term storage options.

Digital Versatile Disk

Least expensive method for long-term archiving per gigabyte.

Archive

A place where records or documents are preserved

Image manager/ controller

This database contains only the image header information, not the image data

.dcm

File extension of a DICOM image

24 MB

Storage size needed for a mammography image.

HL7

Formed in 1987 and was accepted as the global standard for exchange, integration, sharing and retrieval
of electronic health information.

Gray scale

In digital imaging and radiology, this is known as the basic features that varies in range of tones; black,
white, shades of gray or color.

Spatial Resolution

The ability to distinguish fine detail and differentiate object in an image.

Network

This exists when two or more computers are connected together.

Radiologists

In operative level of network and radiology, this enables viewing and transfer imaging data between
consoles of modalities.

Health care providers

Empowers a healthcare enterprise.

LAN

A type of network that covers a small geographic area like a radiology department.

PACS

A system for digital storage, transmission, and retrieval of radiology images.

ACR - American College of Radiology
NEMA - National Electrical Manufacturers Association

DICOM is developed by

Teleradiology

This refers to the practice of radiologist interpreting medical images while not physically present in the
location where the images are generated.

IHE

This provides implementation profiles based on existing standards like HL7 and DICOM.

Electronic Archive

This serves as the new file room & warehouse for all DICOM imaging modalities.

David Patterson
Garth Gibson
Randy Katz

They coined the term RAID in their article.

Personal Area Network
Global Area Network
Wide Area Network
Local Area Network
Metropolitan Area Network

PAN, GAN, WAN, LAN, MAN

Financial cost
High resolution monitors are needed

Disadvantage of a PACS System

Redundant Array of Inexpensive Disks

RAID stands for

Searching the database and image processing;
Simultaneous display of multiple images on the monitor when the quality of individual images is
decreased or certain segments are cut off;
Appearance of false coloring which appears in the adjacent gray level, false coloring in
contrasting colors, etc.

Disadvantage of DICOM

PACS Central Server
Database System
DICOM Server
Storage System
Interfaces to RIS/HIS
Web Server for Remote Access
PACS Workstation

Enumerate the (7) basic components of a PACS System

HL7
DICOM
IHE

Enumerate the 3 significant health care standards important to a radiologist

1. Interoperability Problem Identification
2. Integration Profile Specification
3. Implementation and Testing at Connectathon
4. Integration Profile Conformance Statements

Enumerate the 4 stages of IHE accomplishes

1. Verification
2. Storage
3. Query/Retrieve
4. Print/Management
5. Procedure Step
6. Media Storage
7. Structured Reporting

Enumerate at least 5 DICOM service classes in Radiology

1. Image Acquisition - any modality used to acquire medical images
2. Communication Network - transmit images and attached data
3. Patient Data - HIS/RIS interface according to PACS
4. Display of images - interactive and can be manipulated
5. Recordings Archive - centralized archiving for images
6. Web Server - provides adequate access and display of data to employees

Enumerate at least 3 out of the 6 main components of a PACS System and briefly describe its use
