CT Perfusion Phantom - Gammex 432-BRN
Confidence in Perfusion Studies

Finally you can answer those questions with the Gammex CT Perfusion Phantom.

CT brain perfusion studies can play a key role in evaluating many disorders including stroke and help to identify patients who may benefit from thrombolytic therapies. Now there is an easy-to use contrast-simulation tool to help ensure that your CT scanner and perfusion software are providing you consistent results. The CT Perfusion Phantom is designed to mimic the injection of a contrast bolus into a region of interest allowing you to generate precise time attenuation curves (TAC), of differing velocities, to better monitor your CT Perfusion program, and patients. Once you benchmark perfusion rates and TACs for each system using the Gammex Perfusion Phantom, you will be better positioned to know if future measurements show a true change, or if follow-up results are within the precision error of the measurements. Use the dose port to optimize imaging and perfusion protocols and results at the lowest possible dose.
