A LabVIEW™ based multichannel recording architecture for high density electrical mapping

The goal of our work is to describe and test a novel multichannel recording equipment architecture for cardiac mapping based on LabVIEW: the Reconfigurable Architecture for Electrical Mapping (RAEM). The RAEM architecture covers the communication between a generic acquisition hardware and a computer by means of a FPGA and a Real-Time Controller. Evaluation of the performance, versatility and limitations of the presented architecture has been done by using three different National Instruments (NI) hardware solutions (Single-BoardRIO-9631, Single-BoardRIO 9642 and the CompactRIO-9024+CompactRIO-9104). Maximum data throughput obtained for each hardware solution were: 19, 24 and 51 Mbps. The design of the RAEM system, based on LabVIEW and RIO hardware, allows migration to new hardware platforms keeping the same architecture.
