Exposure II - SECTION 3

Storage of medical images on a short-term basis (3–6 months), providing quick, rapid access, is achieved through the use of:

• portable, external computer hard drive

• a digital “jukebox” storage device

• cloud storage

• RAID storage

Communications involving healthcare information (e.g., demographics) follow:

• FDA regulations

• grayscale display standards

• HL-7 standards

• DICOM regulations

Gray scale bit depth determines:

• the number of gray shades

• pixel size

• pixel pitch

• image resolution

Hospitals use a _______ to assist ordering providers in selecting appropriate imaging exams:

• clinical decision support system

• electronic medical record system

• DICOM standard

• voice-activated dictation system

A grainy, reticulated image that cannot be corrected postprocessing is caused by:

• Quantum mottle

• Overexposure

• Motion blur

• Grid cutoff

To manage large image file sizes, radiology departments use:

• electronification

• laser digitizing

• network protocols

• data compression

Which is an advantage of digital over film?

• Digital images can be manipulated without re-exposure

• Digital images can be sent remotely

• Digital images need less physical storage

• all of the above

A network for storing, distributing, and viewing medical images is called:

• RIS

• PACS

• EMR

• VNA

The DICOM standard was created to:

• eliminate small vendors

• establish common exposure dose values

• allow various vendors to share digital data without proprietary software constraints

Modern Internet-based storage solutions for imaging departments use:

• in-house archival technologies

• portable storage devices

• cloud computing

• RAM storage
