Chapter 18 (Picture Archiving and Communication System - PACS) Flashcards
PACS and Digital Imaging
What does PACS stand for, and what is its function?
Picture Archiving and Communication System – Manages image acquisition, viewing, storage, and retrieval in medical imaging.
PACS and Digital Imaging
What are the four main components of PACS?
- Image Acquisition System
- Display System
- Network
- Storage System
PACS and Digital Imaging
What is DICOM, and why is it important?
Digital Imaging and Communications in Medicine – A universal format ensuring compatibility between different imaging systems.
PACS and Digital Imaging
What does teleradiology allow?
Remote transmission and viewing of medical images for diagnosis.
PACS and Digital Imaging
What two organizations developed DICOM?
- American College of Radiology (ACR)
- National Electrical Manufacturers Association (NEMA)
Electronic Medical Records (EMR) & Radiology Workflow
What does EMR stand for, and how does it relate to PACS?
Electronic Medical Record – A digital health record system that integrates with PACS for storing patient imaging history.
Electronic Medical Records (EMR) & Radiology Workflow
What is the main benefit of PACS over film-based storage?
Faster image retrieval, reduced storage space, and improved workflow.
Electronic Medical Records (EMR) & Radiology Workflow
Who is responsible for interpreting medical images in diagnostic radiology?
Radiologists.
Electronic Medical Records (EMR) & Radiology Workflow
Who is responsible for interpreting medical images in radiation oncology?
Radiation oncologists.
Electronic Medical Records (EMR) & Radiology Workflow
What does lexicon mean in medical imaging?
A standardized vocabulary used to describe imaging processes.
Electronic Medical Records (EMR) & Radiology Workflow
What does ontology refer to in radiology?
The relationships between standardized medical terms (e.g., linking CT scan to anatomy terminology).
Electronic Medical Records (EMR) & Radiology Workflow
How does workflow efficiency improve with PACS?
Reduces delays in image processing, enhances communication, and speeds up diagnosis.
Medical Image Storage & File Sizes
What determines the file size of a digital medical image?
Image resolution, bit depth, and compression type.
Medical Image Storage & File Sizes
How does compression affect image storage in PACS?
Lossless compression retains all details, while lossy compression reduces file size but loses some quality.
Medical Image Storage & File Sizes
What imaging modality typically has the largest file sizes?
CT and MRI due to multiple slices and high resolution.
Medical Image Storage & File Sizes
How does network speed affect PACS performance?
Faster network speeds improve image transmission and retrieval times.
Medical Image Storage & File Sizes
What is the biggest concern with digital imaging security?
Protecting patient data (HIPAA compliance) from unauthorized access.
Medical Image Storage & File Sizes
What does SIIM stand for?
Society for Imaging Informatics in Medicine, an organization that supports digital imaging advancements.
Medical Image Storage & File Sizes
What does ARRT stand for?
American Registry of Radiologic Technologists, responsible for licensing radiologic professionals.
Medical Image Storage & File Sizes
Why is PACS integration with EMR important?
Allows radiologists and physicians to access imaging data directly from patient records.
