Method for safekeeping static and dynamic positioning accuracy of e.g. stationary C-arm in medical practice area, involves solving motion equation, and utilizing absolute actual position of external loads in image processing method

摘要

The method involves determining an absolute actual position of external loads e.g. radiators (ST1) and detectors (D1), of a tripod system (CBT1) i.e. C-arm (CB1), by sensor systems e.g. acceleration sensors, distance sensors and optical sensors. A motion equation for the external loads of the tripod system is solved in a predefinable time range by time integration on the absolute actual position. The absolute actual position of the external loads is utilized in an image processing method that is utilized for identification of a projection camera angle. An independent claim is also included for a tripod system.
