Holds information, not imaging HL-7 - Health level 7
Provides a framework for the exchange integration sharing, and retrieval of electronic health information Standard protocol for information (HL-7)
Consists of many parts and is used at many levels within various hospital systems HL-7
What does EMR stand for Electronic medical record

What does DICOM stand for Digital image commutations in medicine
Links everything together DICOM
Who developed DICOM ACR - American college of Radiology NEMA - national electrical manufactures association
What does PACS stand for Picture archiving and communication system
What does RAID stand for redundant array of independent disks
Short term memory RAID
Long term memory PACS
connects many computer users and devices to a system PACS Network
Remote transmission PACS teleradiology/remote connectivity
The DICOM gray scale function Assures that pixel failures are displayed at the proper luminescence. Producing a more consistent image (allows it to transfer)
When there is no loss of image quality Lossless compression
When some loss of image quality occurs and must be used with care Lossee (lossy)compression
Why is compression useful Helps reduce the consumption of expensive resources, such as hard copies, disk space, transmission band width
What must be done to view a compressed image uncompressed
Disadvantages of PACS Downtown/ when the system goes down
Workflow How a process is done step by step or how a task is completed
How one completes an exam from order entry to transcribed report Workflow

Plan for the systematic observation and assessment of the different aspects of a project or service to make sure the standards are being met quality assurance
Comprehensive set of activities designed to monitor and maintain systems that produce a product quality control
When all images completed at the modality make it to the PACS Data integrity
Quality control standards are set by who ACR - America college radiology
What are the quality control standards requires compliance with standards of practice to ensure quality in any imaging system
What does TQM stand for Total quality management
Overall efficiency and effectiveness of imaging systems. Are evaluated beyond the mechanics of producing a image TQM - totally quality management
