Product Short Description
Product Introduction
The GE HD DIFB 5194006-3 is a High-Definition DAS (Data Acquisition System) Interface Board designed for GE HealthCare Computed Tomography (CT) scanners, specifically integrated into DAS subsystems like VCT HD, HALO LS64, Sherlock to HALO Upgrade Kit, and CT DAS assemblies. It acts as the core interface between A/D converter modules and the DAS Controller Board (DCB), receiving raw scan data from detectors, executing low-level processing (including data formatting, noise reduction, and synchronization), and transmitting processed data via LVDS to the DCB for further reconstruction. The board incorporates high-precision SMT components, a lead-free power supply sequencer, LVDS dual CMOS differential line receivers, and a Cast CAN IP Core for reliable communication. It ensures consistent data integrity and signal stability in high-speed CT scanning environments, supporting high-resolution imaging with minimal latency. The HD DIFB 5194006-3 is a critical replacement part for maintaining scanner uptime, with a substitute part number 5143018 and a remanufactured variant (5194006-3-R) available for exchange programs. It complies with medical device quality standards, featuring robust construction with enhanced durability for continuous clinical operation.
