Thermal Camera Detection of Ventriculoperitoneal Shunt Flow

There have been reports in the past of using thermal cameras to demonstrate flow in the tubing as a surrogate of proper shunt function. This was shown to have almost 90% accuracy at determining proper functioning but required expensive equipment that was not universally available. There is now smart phone based thermal camera technology (Flir One: http://www.flir.com/flirone/) that could make this technique widely available for health care use. The goal of the study is to determine if this device can demonstrate flow in the distal tubing of a VP shunt.
