SRS & MultiMets Commissioning
The uniform body of this device makes it ideal for commissioning since there is no need to model the phantom within the planning system using contour density adjustments. The NavPhan allows you to accurately measure the composite dose for the smallest lesions that you will treat clinically thus increasing confidence in your delivery systems.
Patients Specific SRS QA
Composite radiosurgery plans are fully validated beyond the TG-218 standard because the image guidance, 6-D.O.F. couch and dose distribution are all verified during each QA measurement.
Submillimeter setup accuracy
<0.2mm and <0.1° achievable[1]. This is the only system that exactly aligns the measurement plane with that extracted from the dose distribution thus eliminating a common source of error in small field QA.
Unmatched Multiple
Mets Capabilities
-
This is the only phantom that allows you to measure a dose plane that does not intersect with the isocenter of the machine. This capability is an absolute necessity if you wish to verify most single isocenter multiple mets plans. [2]
-
Measure the smallest targets up to 85mm off axis.
Perform Routine Imaging and
Setup QA Mets Capabilities
8-Fiducial markers within the phantom allow routine verification of the patient setup systems.
Software Included
The included software enables you to navigate a 3D DICOM dose distribution and extract any measurement dose plane with ease at any desired resolution.
