Chapter 9 Flashcards
refers to the collection, classification, storage, retrieval, and
dissemination of recorded information.
Informatics
It plays a pivotal role across various
domains, including healthcare, business, and scientific research.
Informatics
A critical subspecialty within informatics is ____, which focuses on the exchange of medical image information within radiology departments and
across the broader medical enterprise.
imaging informatics
- handles administrative data such as patient demographics, financial
records, and patient location tracking within the hospital.
Hospital Information System (HIS)
- focuses on the clinical data and may integrate with the HIS, designed to
manage patient care information.
Clinical Information System(CIS)
- electronically transmits clinician’s order to radiology and other
departments, reducing errors and improving work efficiency
Computed Physician Order Entry (CPOE)
is a comprehensive digital patient record encompassing medical data from various sources, including radiology
EHR
on the other hand, are specific to
individual medical practices.
EMRs
Broader scope, integrating information across multiple healthcare
providers.
EHR
Narrower scope, limited to data within a single healthcare organization
EMR
•Designed for patient scheduling, report storage, patient tracking, examination protocols, and billing.
•Facilitates communication with both HIS and CIS, ensuring streamlined information flow.
Radiology Information System (RIS)
•Supports the storage, retrieval, distribution, and display of medical images.
•Ensures efficient workflow, image quality maintenance, and timely access to prior studies.
Picture Archive and Communication System (PACS)
– each devices can initiate communication and share
resources.
Peer to Peer (P2P)
– servers responds to requests from client devices, managing
data flow and access
Client-Server
Manages and maintain the system, ensuring seamless operation.
PACS ADMINISTRATOR
The ACR together with the National Electrical Manufacturers Assoc.
(NEMA), created a set of standards in ____, this resulted in the creation of
the ____ standard, which has become the universal standard for medical image communication
1985
DICOM
is an international organization that develops standards for the electronic
exchange of clinical and administrative healthcare data.
HEALTH LEVEL 7 (HL7)
In cases where digital transfer is not feasible, the _____ captures the image displayed on a monitor and converts it to a digital format.
frame-grabbing method
Used until the 1990s, adapted for medical imaging by enhancing brightness, reducing distortion, and improving spatial resolution.
Cathode-Ray Tube (CRT) Monitors
refers to saving image data from imaging modalities to an electronic medium for future retrieval._____ can be shared with external physicians or patients.
Archiving Image Data
Immediate access (e.g., hard drives).
Online Storage
Fast retrieval (10-30 seconds) via systems like optical jukeboxes or tape libraries.
Near-Line Storage
Requires manual retrieval and is prone to risks like data loss through mishandling
Offline Storage
systems distribute or replicate data across multiple hard drives,
appearing as a single storage device to the computer.
RAID
is the most common configuration for PACS archives, offering a balance of performance and redundancy
RAID 5
Within a specific department (e.g., from the CT scanner to a radiologist’s
workstation).
Department-Wide
Across hospital facilities for referring clinicians.
Hospital-Wide
Extending to external locations like outpatient clinics or remote radiologists
Enterprise-Wide
