With CIRS now part of Sun Nuclear, we are optimizing our portfolio of Quality Management solutions. As part of this process, the MultiPHAN is no longer being manufactured or sold by Sun Nuclear. We are pleased to offer the CIRS Daily ISO Phantom as a suitable alternative.
Accurate radiation dose delivery requires daily checks of the alignment between true radiation isocenter and the isocenters of the imaging, localization and targeting systems. The CIRS Daily ISO Phantom (Model 023) provides a cost-effective, quick, and accurate means for testing isocenter coincidence.
Accurate, Economical, Easy-to-Use
With the Daily ISO Phantom, the linac lasers and light field can be “tuned” to true radiation isocenter using engraved markings on the phantom’s exterior. Light field and radiation field alignment can then be checked via integrated radiographic markers. Importantly, on-board imaging systems and EPID isocenters can also easily be assessed for true spatial alignment and coincidence with that of the treatment beam.
The Daily ISO Phantom contains a unique center point fiducial and an offset target, both ceramic and measuring 6.35 mm in diameter. The offset target helps ensure the accuracy of table offset coordinates generated by kV/MV matching -- by locating the target, moving the table by determined amounts, and verifying positioning at isocenter.
Machined with concentric circle exterior targets, the Daily ISO Phantom allows users to objectively assess all setup errors, including rotations, and to easily align to true radiation isocenter.
The Daily ISO Phantom is manufactured with machining tolerance of ± 0.02 mm, and a target positioning accuracy of ± 0.1 mm.
