Study Notes
Imaging Equipment and Systems
- Imaging technologies include CT (Computed Tomography), MR (Magnetic Resonance), and Ultrasound.
- Imaging information systems comprise HIS (Hospital Information Systems), RIS (Radiology Information Systems), and PACS (Picture Archiving and Communication System).
- Peripheral equipment includes workstations, 3D printers, and CD importers for processing and managing images.
Brief History of DICOM and Standards Development
- 1983: ACR and NEMA established a Standards committee for radiologists and equipment vendors.
- 1985 & 1988: Release of the first two versions of ACR-NEMA 300, leading to improved vendor acceptance.
- 1993: Introduction of DICOM standards supporting local area networks (LAN) using Ethernet and TCP/IP protocols.
- 2005 & 2007: Addition of Radiation Dose Structured Reports (RDSR) tailored for x-ray and CT imaging.
- 2013: Second generation of RESTful web services (DICOMweb) launched for retrieving, storing, and querying DICOM images.
- 2019: Redocumentation of DICOMweb provides a clear structure for web implementers concerning DICOM web services.
DICOM Metadata Structure
- DICOM metadata uses a paired hexadecimal format, each part representing specific data groups and attributes.
- Patient-related data is tagged with (0010), while unique identifiers (UID) are utilized for studies, series, and instances.
- Example DICOM tags: Patient's name (0010,0010), referring physician's name (0008,0090).
PACS Core Components
- PACS comprises four primary components: Acquisition, Archive, Display, and the Image Database.
- Acquisition refers to image collection; Archive manages storage; Display enables viewing; Image Database tracks status of images.
- RIS integrates with PACS for managing radiology orders and billing information.
Key Systems and Standards
- HIS: Used for storing and retrieving comprehensive patient information.
- RIS: Manages radiology data, enhancing order tracking and billing processes.
- HL7: Provides standards for data transfer among healthcare providers.
- PACS: Facilitates long-term management, retrieval, and presentation of medical images.
Importance of DICOM
- DICOM is the global standard for medical imaging interoperability, enabling various systems to efficiently produce, store, display, and transmit medical images.
- Developed collaboratively by ACR and NEMA, DICOM is recognized as ISO 12052 by the International Organization for Standardization.
- Ensures clinical effectiveness through defined formats for medical images and related data exchanges.
