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.

100% MR Safe
Efficient piezoelectric motor assembly with no ferrous content allows for quick, easy and precise operation in Magnetic Resonance Imaging suites with no projectile hazard up to 7T.
The patent pending piezoelectric motor design employs highly effective proprietary RF noise suppression techniques with optimized shielding to preserve MR image quality with no phantom induced image artefacts.
The MR safe motor assembly is directly-coupled to the 20 cm deep body oval phantom for easy set-up, positioning and efficient operation in the head-first or feet-first direction for commissioning and routine 4D-MRI QA.
Body Oval Phantom
Contains offset and central cylindrical thru holes, which provide low or medium body mass attenuation, for interchangeable stationary and motion inserts.
Includes two configurable inserts with two stems, two spherical targets and six stem base lids for testing multiple 4D motion tracking and dosimetry applications.
Integrated phantom design along with easy-to-use motion software saves time and increases operational efficiency by reducing or eliminating the need for complex or tedious assembly before operation.
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.
