QUASAR Rotation Stage Respiratory Motion Phantom Brochure

Product catalog summary

Overview: The document describes the addition of a Rotation Stage to the QUASAR™ Respiratory Motion Phantom, enhancing its capabilities for quality assurance (QA) in radiotherapy by introducing non-linear motion.

Key Features:

The Rotation Stage allows for more complex motion, expanding the range of possible tests.
It supports a total range of motion of 60 degrees (±30 degrees from the horizontal).
Various inserts with off-center tumors and geometric objects are available to simulate complex motion scenarios.

Offset Inserts:

Three cedar inserts with off-center 30 mm spherical tumors are available for testing complex lateral motion.
These inserts are compatible with the existing Cedar Series respiratory motion inserts.
The 4D CT imaging insert is also supported due to the off-center positioning of geometric objects.

Quality Assurance System:

QUASAR™ supports testing of dosimetric and non-dosimetric functions of planning systems, CT simulators, and delivery systems.
It is integral to QA programs, useful for commissioning new systems, upgrades, and testing repairs.

Ordering Information:

Product code for the Respiratory Motion Rotation Stage: 500-3330.
Optional items include various Offset Cedar Inserts with solid or split tumors.

Installation Instructions:

Remove the existing thumbscrew and slide the translation stage out of the motion assembly.
Insert the modified translation stage and align the T-nut.
Insert the extended thumbscrew through the keyhole and into the T-nut.
Adjust the T-nut location to a maximum 20 mm amplitude and finger tighten the thumbscrew.
Verify alignment to prevent binding and motor skipping, starting with a slow speed.
Solid acrylic inserts are limited to 25 bpm; cedar inserts have no speed limit.

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

QUASAR Rotation Stage Respiratory Motion Phantom Brochure-2

RESPIRATORY MOTION ROTATION STAGE Add Non-Linear Motion to the Respiratory Motion Phantom Installation Instructions Procedure: 1. Remove existing thumbscrew completely and slide translation stage out of motion assembly. 2. Slide modified translation stage into motion assembly, note location of thumbscrew T-nut. 3. Slide extended thumbscrew through opening in keyhole, and then carefully insert into T-nut through opening in translation stage. 4. Adjust location of T-nut to maximum 20 mm amplitude. 5. Finger tighten the thumbscrew. 6. Review alignment of motion assembly relative to oval / insert....
