DICOM Interface Module

The DICOM Interface Module is a component of a Treatment Planning Station that enables the import, export, and processing of medical imaging data in compliance with the Digital Imaging and Communications in Medicine (DICOM) standard. It acts as a communication bridge between treatment planning software and imaging equipment such as CT scanners, MRI machines, and PET scanners, ensuring data transfer, format conversion, and protocol handling for radiation therapy planning. The module implements DICOM protocols to establish network connections, receive image sets and metadata, validate and convert data, and make it available to the planning software. It typically includes DICOM Service Class Provider (SCP) and Service Class User (SCU) functionalities for storage, query/retrieve, and verification services. The module is housed in a plastic enclosure with a printed circuit board and electronic components. It operates on a wide input voltage range of 9–36 V DC, consumes 5–15 W, and functions in ambient temperatures of 0–40 °C. Storage temperature ranges from -20 to 60 °C, and relative humidity is 10–90% non-condensing. Ingress protection is rated IP20–IP42 per IEC 60529, depending on enclosure. Communication is via Ethernet with auto-negotiation at 10/100/1000 Mbps per IEEE 802.3. DICOM conformance is version 3.0 per DICOM PS3. Sustained data transfer rate is 10–100 MB/s. Dimensions are 150×40×120 mm (W×H×D), and weight is 0.5–1.0 kg depending on configuration. Mean time between failures (MTBF) is calculated at 50,000 hours per Telcordia SR-332. These values are reference ranges; verify model-specific specifications with the legal manufacturer. The module is intended for integration into Treatment Planning Stations and is not a standalone device. It requires a compatible host system and network infrastructure. For procurement, confirm DICOM conformance, electrical ratings, and environmental limits with the supplier.

The module operates by implementing DICOM protocols to establish network connections with imaging devices. It acts as a DICOM SCP to receive image sets and metadata, and as an SCU to query/retrieve from other devices. It validates incoming data, performs format conversion if needed, and transfers the data to the treatment planning software via an internal interface. The module handles storage, query/retrieve, and verification services, ensuring reliable data exchange. It uses Ethernet for network communication and manages data flow at rates up to 100 MB/s. The module's firmware manages protocol handling and data integrity. It is powered by a DC supply and operates within specified environmental limits. The module does not perform image analysis; it only facilitates data transfer and protocol compliance.
