Enterprise Imaging and Network Solutions Review

This set of vocabulary flashcards covers clinical imaging modalities, network topologies, communication protocols, and quality assurance pillars within healthcare IT.

X-ray (Radiography)

Used as the primary frontline line of defense to detect structural bone fractures, acute infections, and anatomical abnormalities.

Computed Tomography (CT)

Employs rotating X-ray tubes to generate multi-planar cross-sectional images critical for diagnosing complex internal conditions.

Magnetic Resonance Imaging (MRI)

Uses strong magnetic fields and radiofrequency pulses to yield high-contrast, detailed images of soft tissues for neurological and musculoskeletal imaging.

Ultrasound

Utilizes high-frequency sound waves to monitor fetal development in real-time and examine solid abdominal organs.

Positron Emission Tomography (PET)

Observes in vivo metabolic processes and cellular function, frequently fused with anatomical modalities like CT or MRI.

Nuclear Medicine

Introduces radiopharmaceuticals into the patient to functionally evaluate organ processes rather than just evaluating shape.

Mammography

A specialized low-dose X-ray technique dedicated specifically to the early screening and detection of breast cancer.

Fluoroscopy

Delivers real-time moving radiographic images onto digital monitors to guide dynamic diagnostic and therapeutic interventions.

DEXA (Dual-Energy X-ray Absorptiometry)

Employs dual-energy beams to accurately measure bone mineral density to diagnose and monitor osteoporosis.

Interventional Radiology (IR)

Focuses on executing minimally invasive therapeutic procedures directly navigated by advanced live imaging techniques.

Radiology Information System (RIS)

The central brain managing the administrative data flow of the department, encompassing patient management, scheduling, and billing.

Star Topology

The standard network design where every single clinical workstation hooks up independently to a core centralized server.

Mesh Topology

A redundant framework where multiple servers and key clinical workstations are cross-connected to deliver high uptime and bypass dead connections.

Client-Server Architecture

A setup where workstations function as clients communicating with a central master server that handles storage and access permissions.

Distributed Architecture

An architecture where multiple physical servers are spread out over several geographic regions to support high scalability and redundancy.

DICOM (Digital Imaging and Communications in Medicine)

The global language used for storing, retrieving, and sending medical images, including visual pixel data and metadata tags.

HL7 (Health Level Seven)

The universal text protocol that allows administrative hospital systems to transfer demographic records, diagnostic reports, and billing updates.

TCP/IP

The fundamental protocol suite that breaks DICOM and HL7 messages into packets for accurate transmission across networks.

VPN (Virtual Private Network)

Creates a protected, encrypted data tunnel through public networks to allow remote specialists to review exams securely.

LAN (Local Area Network)

A network layout structure designed for fast image movement within a single clinic building.

WAN (Wide Area Network)

A network layout structure used to connect remote sites and hospitals across a wider geographic area.

Lossless Compression

Algorithms used to shrink file sizes for fast network transfers while keeping image quality intact.

Vendor Neutral Archives (VNA)

Decouples image storage from the specific PACS vendor by saving files in a highly standardized format for long-term accessibility.

HIS Integration Report

A detailed administrative document mapping exactly how a hospital's internal software applications interact and share data flows.

Decision-Making Assurance

The rigorous data validation practices used to ensure system deployment choices are backed by accurate metrics and proven methodologies.

Medical Imaging QA

The pillar of QA focused on format standardization, equipment calibrations with imaging phantoms, and auditing images for artifacts.

Data Storage QA

The pillar of QA involving automated off-site data backups and the use of cryptographic checksums to spot file corruption.

Disaster Recovery QA

The pillar of QA involving the writing and testing of a Disaster Recovery Plan (DRP) and a Business Continuity Plan (BCP).

Data Flow Fault-Tolerance QA

The pillar of QA focused on path redundancy through network loops and automated alerting systems to flag transmission errors.

Networking Latency QA

The pillar of QA involving bandwidth optimization and Quality of Service (QoS) rules to prioritize massive DICOM files.
