ImagingRing

A new European patent application (Patient Positioning and Imaging, European patent application file 12 17 7255.8 (U2213 EP)  June 2012  submitted by Heinz Deutschmann) describes an innovative solution for in-isocenter imaging: The ceiling mounted robotic system for patient positioning and imaging offers large working spaces and is currently under construction for MedAustron by a consortium of B-E-C (Reutlingen, D) and medPhoton (Salzburg, A). The ImagingRing system combines Patient Alignment with a sliding Imaging Ring (IR), which comprises an independently rotating X-ray source and a flat panel detector. The system enables accelerated volumetric cone beam computed tomography (CBCT with up to 5 rotations/min) and offers ultrafast 2D/3D imaging and registration protocols (maximum framerate 30 Hz). The clearance of the imaging ring is comfortable 78 cm in diameter and equivalent to the maximum field of view (FOV) of 78 cm in the central plane, the full resolution maximum FOV is 60,5 cm (360° acquisition). Furthermore, the system is capable of dual energy X-ray imaging to improve soft tissue or bone contrast and is developed for 4D tracking applications to allow motion compensation intra-fractionally. The robot handles 350 kg loads and is therefore able to lift and align patients up to more than 200 kg mass in six degrees of freedom, can be combined with an additional linear axis to enlarge the working space to fulfill the extended requirements in particle therapy.
