Quality Assurance And E2E Testing On Cyberknife System
“Strict QA procedures for the imaging, planning and delivery of radiotherapy using respiratory
management devices are required to ensure the safe and effective use of test devices.”
The CIRS Model 18023-A Xsight® Lung Tracking “XLT” Phantom Kit and Model 18043 4D Planning “4DP” Phantom have been verified and validated by Accuray for use with CyberKnife systems and both are designed to work in conjunction with the Synchrony System.
The XLT phantom body represents an average human thorax in shape, proportion and composition.
4D Planning Phantom
The 4DP phantom can be interchanged with the XLT body and connected to the motion controller and platform.
Xsight Lung Phantom Ball Cube Rod
The XLT and 4DP phantoms include a single dosimeter rod made from lung equivalent epoxy
(of respective densities). It contains a spherical target that accommodates two pre-cut
Radiochromic® films, and is easily connected and aligned to the drive shaft.
4D Treatment Optimisation & Planning System
The optional 4D Treatment Optimization and Planning System on the MultiPlan System allows the user to visualize the effect of respiratory tissue deformation on the radiation dose isocontours and metrics of a treatment plan. As a result, treatment plan can be developed with optimized beam positions and weights based on respiratory deformation knowledge.
The 4D Planning “4DP” Phantom used in conjunction with the XLT phantom kit permits testing of this optional 4D Planning System on the MultiPlan System with the CyberKnife System.
