• Pullback travel indicator verifies distance accuracy • X-ray source length gauge confirms the source length is within the specification and provides the source length position offset dimension • Applicator depth gauge verifies the balloon applicator lumen length is within the specification and gathers the applicator length position offset dimension • CT-compatible marker catheter represents possible x-ray source pullback positions within a balloon applicator and is visible using a CT scanner • Fluoro-compatible marker catheter represents potential x-ray source pullback positions within a balloon applicator and is visible with fluoroscopic imaging • Storage and carrying case permit convenient portability and ensure the protection of the kit The versatile Xoft® Axxent® Electronic Brachytherapy (eBx®) System® utilizes breakthrough electronic brachytherapy technology to provide expanded treatment options for a range of cancers. With the Xoft System, highly focused therapeutic radiation of the disease target is possible in a minimally shielded setting, while sparing surrounding healthy tissue. The Axxent Physics Accessories Kit allows physicists to perform quality assurance tests to confirm that the Xoft System is operating properly. Prior to treatment, the kit, with its specialized gauges and catheters, may be used to confirm key system parameters and component specifications. The shielded test fixture allows quality assurance tests of the Xoft System while concurrently providing a shielded environment for the x-ray source. The kit is a valuable tool that ensures proper functioning of the Xoft System. Product Datasheet www.xoftinc.com MC475 Rev A
