QUASAR™ MRI-Compatible Respiratory Motion Phantom

The QUASAR™ MRI-Compatible Respiratory Motion Phantom is designed to move a cylindrical insert, filled with liquid or gel, within a water filled body shaped oval.

The programmable phantom is capable of moving inserts in the superior/inferior direction at varying speeds and amplitudes. A more complex 3D motion profile is achieved by twisting the insert during translation. Interchangeable inserts are available for imaging, planning, targeting and delivery QA.

The QUASAR™ MRI-Compatible Respiratory 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 better, 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.

  • Flexibility to move inserts along a straight line or rotate with a twist to create 3D motion
  • Cost-effective way to increase overall testing capabilities
  • Install the software on an unlimited number of computers at all official sites

Motion QA Software Included

The QUASAR™ MRI-Compatible Respiratory 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 better.

Software Capability Highlights

  • Import patient-specific waveforms
  • Create custom waveforms
  • Edit patient-specific & custom waveforms
  • Adjust the amplitude, stretching or compressing the timeline
  • Filter out high frequency noise, low frequency drift and cardiac signals
