Validation of the Bowman Perfusion Monitoring System: Continuous Real-time Perfusion Quantification


The flow measured by the perfusion probe has been validated for accuracy against flow measured by XeCT in humans1, hydrogen clearance in pigs2 and radioactive and non-radioactive micro-spheres in rat and rabbit livers3.  All probes are calibrated during the process of manufacture for zero flow condition of less than 0.2 ml/100g-min.

The Bowman Perfusion Monitoring System is FDA cleared and CE Marked.
