MRI-pRESPThe 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.

    Benefits

    • Ferrous and artifact free 4D-MRI QA on systems up to 3T
    • Compact design enables operation within the magnet bore with no artefacts or RF noise
    • MRI, CT, PET and LINAC compatible for MR4D vs CT4D, MR-PET and MRgRT 4D QA
    • Control the phantom directly from the console or equipment room with included software
    • Import, create, edit and stream patient-specific or custom waveforms
    • Flexibility to move inserts with translation or with translation and rotation
    • Configurable inserts with optional targets to increase developing and testing capabilities

    Motion QA Software Included

    The QUASAR™ MRI4D Motion Phantom comes with motion QA software which allows you to create, edit and stream programmable or patient-specific respiratory motion waveforms with an editable respiratory range of 1 to 15 seconds per breath.

    Pre-recorded waveforms are imported from a number of real-time respiratory gating systems as well as tab delimited spreadsheet files. Additional edit functions include adjusting the amplitude, stretching or compressing the timeline and filtering out high frequency noise, low frequency drift and cardiac signals.
