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

    • Motor is unaffected by the magnetic field at 1.5T and 3T
    • Diamagnetic phantom produces negligible susceptibility artefacts/image distortion
    • RF shielded to operate within the magnet bore and does not degrade SNR in MRI images
    • Easy to set up and operate
    • MRI, CT, PET and LINAC compatible for MR4D vs CT4D, MR-PET and MRgRT 4D QA
    • Operate MR safe phantom directly from the control room
    • Requires no additional programming to stream patient-specific respiratory motion waveforms
    • Move inserts along a straight line or rotate with a twist to create 3D motion
    • Select from a variety of cost-effective interchangeable inserts to increase overall testing capabilities

    Motion QA Software Included

    The QUASAR™ MRI4D Motion Phantom comes with motion QA software which allows you to display, edit, and run programmable or patient specific respiratory motion waveforms. Pre-recorded waveforms are imported from a number of real-time respiratory gating systems as well as tab delimited spreadsheet files.

    Users can also create, edit and save custom respiratory waveforms with an editable respiratory range of 1 to 15 seconds per breath. Additional edit functions include adjusting the amplitude, stretching or compressing the timeline and filtering out high frequency noise, low frequency drift and cardiac signals.

    The motion QA software application runs on desktop or laptop computers and is compatible with Windows 7 or higher.
