Victoreen® Model 7200 Double Check™
Introduction

The Model 7200 Double Check™ is a portable, easy-to-use, daily check device for therapy beam quality assurance. Ten ion chambers are positioned to simultaneously check beam constancy, symmetry, flatness, and energy constancy. Nine ion chambers are used for verification of flatness, symmetry, and dose constancy while a special filtered ion chamber provides energy constancy information. Its unique, detachable detector and the included 50 ft (15 m) cable allow the Model 7200 to be used as a single module or a two-piece, remote readout device. The large LCD, accessible internal measurement storage, and computer interface provide for ease of use, comparison, and record keeping.

Applications
The Double Check™ performs quality assurance tests for linear accelerators and Cobalt 60 therapy machines. The quick setup and operational ease of the system make it ideal for daily checks of beam constancy, symmetry, and flatness. Consulting physicists and service engineers will appreciate the Double Check™ System's portability. An optional carrying case eases transport and storage.
