Controllable resolution imaging array

An imaging device for radiation imaging consists of an array (80, 82, 84) of detector cells and an array of image cell circuits. Each detector cell is connected to the corresponding cell in the array of image cell circuits. Each individual cell in the detector cell array generates a charge based on the radiation that hits the cell. Each cell in the array of image cell circuits accumulates the charge in a storage capacitor. The storage capacitor can be, for example, the gate of a transistor. Single detector cells (86) can be grouped together to form larger area super cells (88, 90), the size of which can be controlled by control signals, which select the operating mode. The output from a single cell or a super cell is read out in current mode and the output from a super cell is scaled according the size of the cell to produce an average current. Several modes can be implemented in the imaging device. Also, an imaging system for larger area radiation imaging can be implemented by connecting several imaging devices together in the form of a two dimensional array.
