QUASAR Catphan® Shaker Aug 23, 2011

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

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.

A chest wall platform moves in the anterior/posterior direction. This platform is compatible with motion tracking systems from multiple vendors.
