The programmable QUASAR™ MRI4D Motion Phantom is designed to move liquid or gel-filled cylindrical inserts within a water-filled body shaped oval at varying speeds and amplitudes.
The phantom is capable of moving inserts in the superior/inferior direction as well as producing a more complex 3D motion profile by twisting the insert during translation. Interchangeable inserts are available for imaging, planning, targeting and delivery QA.
The QUASAR™ MRI4D Motion Phantom uses the same software application as the QUASAR™ Respiratory Motion Phantom to display, edit, and run patient-specific respiratory waveforms. Waveforms are created using the application or imported from vendor-specific MR respiratory tracking systems or from tab-delimited spreadsheet files.
The software application is compatible with Windows 7 or higher and runs on desktop or laptop computers. Create, import, edit, and save respiratory waveforms with the QUASAR™ Respiratory Motion Software application. Edit functions include adjusting the amplitude, stretching or compressing the timeline and filtering out high-frequency noise, low-frequency drift and cardiac signals.
