Abstract
In a planar radiation image detector with a number of photosensor elements arranged like a matrix, the photosensor elements being activated via at least one associated switching element and each exhibiting at least one storage element with a predetermined capacity, the storage elements are arranged above and/or below the photosensor elements. With such a planar image detector, an improved ratio of active detector surface to total detector surface is achieved.
Claims21
A planar image detector comprising:
- a plurality of phototransistors in a matrix;
- a plurality of switching elements respectively associated with the plurality of phototransistors for individually activating the respective phototransistors;
- at least one storage element with a predetermined storage capacity associated with each phototransistor;
- and
- a predetermined number of phototransistors in said plurality of phototransistors each comprising a gate electrode, a source electrode and a drain electrode, said gate electrode having a gate metallization with a gap therein between said source electrode and said drain electrode.
