„
Communicate with phantom through local area network
Requires no additional programming or customization
Ability to rotate inserts as they translate to create 3D motion
Supports a wide range of ion chamber / film dosimetry options
Works with 8 cm diameter QUASAR™ inserts
Compatible with VXP, .CSV, .TXT, .DCM, .LOG, .DAF, .IMA
Install the software on an unlimited number of computers
The QUASAR™ Cylindrical Respiratory Motion Phantom can run with or without a computer and is suitable for QA of most
external beam installations including 3D conformal radiation therapy and intensity modulated radiation therapy (IMRT)
systems. It can also be used to test imaging systems including x-ray CT, PET and SPECT.
Interchangeable inserts are available for multiple testing applications including film and ion chamber dosimetry. Inserts can be
rotated as they are translated to provide a more complex 3D path.
Motion profiles are programmable and operate in the superior / inferior
direction. A chest wall platform is provided which is compatible with motion
tracking systems from several different vendors.
PATIENT-SPECIFIC SOFTWARE
Included with the phantom assembly is the QUASAR™ Respiratory Motion
QA Software application which allows you to import, create, edit and save
respiratory waveforms. Easily import patient-specific waveforms from a

number of respiratory gating machines including Varian Realtime Position Management™ (RPM), Anzai, Cyberknife, Philips,
Respisens, and Siemens. Quickly create custom waveforms
or import unique waveforms produced using tab delimited
spreadsheet files.
