Data Buffer Memory

Temporary data storage component for DICOM medical imaging systems

Component Specifications

Definition
A specialized memory buffer component within DICOM Interface Modules that temporarily stores medical imaging data during transmission between imaging devices and PACS systems, ensuring data integrity and preventing loss during network interruptions or processing delays.
Working Principle
Utilizes high-speed volatile memory (typically DDR SDRAM) to temporarily hold DICOM image data packets as they are received from imaging modalities, buffering them before transmission to Picture Archiving and Communication Systems (PACS). Implements FIFO (First-In-First-Out) or priority-based queuing algorithms to manage data flow and prevent congestion.

Frequently Asked Questions

What is the primary function of DICOM data buffer memory?

To temporarily store medical image data during transmission between imaging devices and PACS systems, preventing data loss during network interruptions and ensuring smooth data flow.

How does buffer memory differ from permanent storage in medical systems?

Buffer memory is volatile temporary storage for data in transit, while permanent storage (like hard drives) retains data long-term. Buffer memory enables real-time data handling without latency issues.

What happens if the buffer memory fails during image transmission?

Image data may be lost or corrupted, requiring retransmission from the source device, potentially delaying diagnosis and increasing network load.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
