title: Real time conductance catheter system based on FPGA.
abstract: This paper presents a digital conductance catheter system based on FPGA (Field Programmable Gate Arrays) to measure real time ventricular volumes for experimental use. The system performance is realized in three stages: a) conductance measurements using a well-known set of resistance connected to each catheter section; b) volumes measurements in glass containers of well-known geometry that contain a solution with a resistivity similar to the blood, and c) comparison between the previous analog conductance catheter system and this novel FPGA based system.
