Multiple Tools for IGRT Quality Assurance

RM PhantomRapidly emerging technologies, such as IGRT and respiratory gating, have led to significant advances in patient treatment.

Gating is one of the many technologies that track tumour motion during the respiratory cycle. To ensure accuracy, respiratory gating also uses QA to simulate the breathing of a patient and account for respiratory motion during radiation delivery.

Modus has developed a line of programmable QUASAR™ Respiratory Motion QA devices that respond to this growing field in radiotherapy.

 

Simulate Patient Breathing

The QUASAR™ Respiratory Motion Phantom is a programmable state-of-the-art breathing simulator for conducting quality assurance testing on radiotherapy systems. Using a personal computer to communicate with the QUASAR™ 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 QUASAR™ Respiratory Motion Phantom is designed to work with different therapy delivery systems and is compatible with kV and MV CT imagers.

Key Features

Key Features

  • Operate the phantom directly from a PC or laptop
  • Stream patient-specific respiratory motion waveforms
  • Interchangeable inserts for multiple testing applications
  • Works with a number of LINACS and motion tracking systems
  • Includes an unlimited multiple site software license

Benefits

  • Communicate with phantom through local area network
  • Requires no additional programming or customization
  • Ability to rotate inserts as they translate to create 3D motion
  • Compatible with third party waveforms including; .VXP, .CSV, .TXT, .DCM, .LOG, .DAF, .IMA
  • Install the software on an unlimited number of computers at all official sites

Patient-Specific Software

Included with the phantom 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 Real-time Position Management™ (RPM), Anzai, Cyberknife, Philips, Respisens, and Siemens. Quickly create custom waveforms or import unique waveforms produced using tab delimited spreadsheet files. Conveniently edit waveforms using a wide range of functions include adjusting the amplitude, stretching or compressing the timeline and filtering out high frequency noise, low frequency drift and cardiac signals.

The software is compatible with Windows 7 or better.
