Patient-Specific Respiratory Motion

The QUASAR™ Programmable Respiratory Motion Phantom is a state-of-the-art breathing simulator for conducting quality assurance testing on radiotherapy systems. Using a personal computer to communicate with the Programmable Respiratory Motion Phantom, the software application downloads patient respiratory waveforms to the phantom, simulating the breathing function.

Used for regularly scheduled testing, as well as commissioning new systems and upgrades, and testing repairs, the Respiratory Motion Phantom is designed to move cylindrical inserts in the superior/inferior direction within a body shaped oval with both varying speed and amplitude. Several different moving inserts are available for a variety of applications.

Insert motion is linked to a moving Chest Wall Platform designed to carry a
respiratory tracking device. The Respiratory Motion Phantom is designed to
work with different therapy delivery systems and is compatible with kV and
MV CT imagers.

The Programmable Phantom includes 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.

Respiratory Motion Rotation Stage

The rotation stage provides a 60° range of motion (±30° from the horizontal) to the QUASAR Respiratory Phantom or Assembly (used with the Multi-Purpose Body Phantom) offering an increased range of QA options.

A new series of offset cedar inserts is available to allow testing with more complex lateral motion during translation.

Respiratory Motion Assembly
Convert your QUASAR Multi-Purpose Body Phantom

The QUASAR Multi-Purpose Body Phantom can be easily converted to an IGRT gating phantom by adding the QUASAR Respiratory Motion Assembly, offering a cost-effective way of increasing overall testing capabilities.

Programmable Upgrade

Upgrade an existing manual Respiratory Motion Phantom or Assembly to function in the fully programmable mode. The QUASAR Respiratory Motion Software Application allows you to simulate patient breathing for accuracy in gated radiation therapy.
