ADC

Back 1

a device for converting analogue signals to digital form

Front 2

DAC

Back 2

digital signal into an analog signal

Front 3

MFT

Back 3

The modulation transfer function is the magnitude response of the optical system to sinusoids of different spatial frequencies. When we analyze an optical system in the frequency domain, we consider the imaging of sinewave inputs rather than point objects.

Front 4

ROC

Back 4

ROC curve, is a graphical plot that illustrates the performance of a binary classifier system as its discrimination threshold is varied

Front 5

PACS

Back 5

PACS server requires not only large storage space for the database butalso data management software to provide the data information service and fastaccess times. It is aninformation system. economical storage and convenient access to images from multiple modalities

Front 6

DICOM

Back 6

solvethe problem of interconnections between different vendors and differentmodalities. Thedata exchange between the imaging modalities, the archive (server) and display workstationsis through the computer networks.

Digital Imaging and Communications in Medicine (DICOM) is a standard for handling, storing, printing, and transmitting information in medical imaging. It includes a file format definition and a network communications protocol

Front 7

HL7

Back 7

Additional software following the Health Level 7 (HL7) standard may beinstalled in the PACS server to handle the text based data information, for theexchange of medical image data. The HL7 standard is defined at the level 7 of the Open Systems Interconnection (OSI) model,the application layer.

Front 8

IHE

Back 8

connects information from PACS, HIS, RIS etc;combines images and administrative data. Improves efficiency in avoiding doubledata, and reduces chance of error occurrence. Combines all information by allhealthcare enterprises.

Front 9

RIS

Back 9

A radiology information system (RIS) is a networked software system for managing medical imagery and associated data. A RISis especially useful for tracking radiology imaging orders and billing information, and is often used in conjunction with PACS and VNAs to manage image archives, record-keeping and billing.

Front 10

HIMSS

Back 10

The Healthcare Information and Management Systems Society (HIMSS) is a nonprofit organization whose goal is to promote the best use of information technology and management systems in the health care industry.

Front 11

HIS

Back 11

The HIS is a larger scale computerized information management systemthat handles three major tasks: supportclinical and medical patient care activities; administer the hospital's daily business transactions; evaluate hospital performances and costs etc

Front 12

CAD

Back 12

Computeraided diagnosis relies on computer algorithms of image segmentation, featuredetection, and classification that are similar to human observer’s imageanalysis. CADis a very active area of current research. Assistdetection or diagnosis – most sophisticated image analysis algorithms. Computer algorithms assistradiologists in clinical decision making (decision support).Utilise image database,information and knowledge for decision support o are procedures in medicine thatassist doctors in the interpretation of medical images.
