QUASAR Rotation Stage Respiratory Motion Phantom Brochure - 1

RESPIRATORY MOTION ROTATION STAGE Add Non-Linear Motion to the Respiratory Motion Phantom The Rotation Stage adds rotational motion to the QUASAR™ Respiratory Motion Phantom for an increased range of QA options. Key Features • Rotation provides more complex motion and expands the range of possible tests • A number of inserts are available with off-center tumors and geometric objects The new accessory allows inserts to rotate as they translate with a 60o total range of motion (± 30o from the horizontal). Offset Inserts Three cedar inserts, each with an off-center 30 mm spherical tumor, allow testing with more complex lateral motion during translation. These inserts feature the same characteristics as the existing Cedar Series respiratory motion inserts (500-3311, 500-3312, 500-3313) but with a modified tumor location. Testing with the 4D CT imaging insert (500-3317) is also supported because of the off-center positioning of the various geometric objects within the insert. Above: Rotation Stage and extended thumbs
