Workflow Step

With the CT Perfusion Phantom, ensure your CT scanner and perfusion software are providing consistent results.

Continuous Improvement for CT Perfusion Programs
Designed to mimic injection of a contrast bolus into a region of interest, the CT Perfusion Phantom generates precise time-attenuation curves (TAC), of differing velocities, to better monitor your CT Perfusion program, and patients.

Benchmark perfusion rates and TACs for each system for better insights into if future measurements show a true change, or if follow-up results are within the precision error of the measurements.

Optimize to Image Gently
Use the dose port to optimize imaging and perfusion protocols and results at the lowest possible dose.

Optimize your CT Perfusion program.

Differing concentrations of simulated blood and contrast move from, arteries, to veins to brain tissue including contrast recirculation

ACR Compliance

Meet ACR CT Perfusion recommendations regarding optimizing technique parameters affecting the radiation dose (kVp, mA and beam collimation) for each scanner type.

FDA Compliance

Follow FDA recommendations for reviewing radiation dosing protocols for all CT perfusion scans to ensure the correct dose, and implementing and adhering to a QA program for review of default protocols and adherence to approved protocols.

Custom Wheeled Case

Water-tight hard case includes built-in wedges to hold and protect the phantom during transport.
