Shaker

The QUASAR™ Catphan® Shaker is designed to enable 4D CT image quality assurance by moving a Catphan® phantom with programmable respiratory and sinusoidal motion profiles.

The Catphan® phantoms are the industry standard for 3D CT image quality assurance. They are used for comprehensive performance evaluation of axial, spiral and multislice CT scanners. Adding motion to a Catphan® phantom allows testing and measurement of image quality at each reconstructed phase of a 4D CT cycle.

The Shaker moves a Catphan® phantom in the superior/inferior direction with programmable motion and amplitude up to 30 mm. Sinusoidal motion is also available with variable speed from 4 to 60 breaths per minute at a fixed 40 mm amplitude. In addition, the Shaker has a chest wall platform moving in the anterior/posterior direction. This platform is compatible with motion tracking systems from multiple vendors.

Key Features

  • Enables testing and measurement of image quality at each reconstructed phase of a 4D CT cycle
  • Moves the Catphan® with programmable respiratory and sinusoidal motion profiles
  • Compatible with motion tracking systems from multiple vendors
  • Run and control the phantom directly from your desktop or laptop computer
  • Communicate with the phantom through local area network (LAN)

Motion QA Software Included

The QUASAR™ Catphan® Shaker comes with motion QA software which allows you to display, edit, and run respiratory waveforms. Waveforms are created in the application or imported from a number of machines including Varian RPM, Anzai, Cyberknife, Philips, Respisens, and Siemens as well as tab delimited spreadsheet files. The software application runs on desktop or laptop computers and is compatible with Windows 7, Vista, and XP.

With the QUASAR™ Respiratory Motion QA 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.

Software Capability Highlights

  • Import patient-specific waveforms
  • Create custom waveforms
  • Edit patient-specific & custom waveforms
  • Adjust the amplitude, stretching or compressing the timeline
  • Filter out high frequency noise, low frequency drift and cardiac signals
