Respiratory Motion Platform

Add multi-directional motion to existing phantoms

The QUASAR™ Programmable Respiratory Motion Platform is designed to move your existing phantoms with programmable respiratory and sinusoidal motion profiles for patient-specific QA.

The Platform’s unique multi-directional motion simulation capability allows it to move in the superior/inferior direction but can also generate a lateral hysteresis motion with amplitudes up to 1.0 cm. This allows testing with phase separation.

With a weight-bearing capacity of 20 kg, the Respiratory Motion Platform can be used to move any QUASAR phantom and most third party phantoms.

The Respiratory Motion Platform includes a Chest Wall Platform - moving in the anterior/posterior direction - which is compatible with motion tracking systems from several vendors.

The Platform comes with a software application which allows you to display, edit, and run respiratory waveforms. Waveforms are created in the application or imported from the Varian RPM system or from tab delimited spreadsheet files. The Software Application is compatible with Windows XP and Windows Vista, and runs on desktop or laptop computers.

With the QUASAR™ Respiratory Motion Software Application you can import, create, edit and save respiratory waveforms. Edit functions include adjusting the amplitude, stretching or compressing the timeline and filtering out high frequency noise, low frequency drift and cardiac signals.
