Portable X-ray detector with grid sensing unit and X-ray imaging system for automatic exposure setting for the portable X-ray detector

摘要

It is described a portable X-ray system (200), which has sensing means for detecting whether an anti scatter grid (230) is attached to a portable detector (240) or not. The system is able to automatically change the default exposure settings (265a, 265b, 265c, 265d), when a grid (230) is removed or attached to the portable detector (240). Thus, the risk of an under- or an over-exposure of the image will be reduced.
