Abstract:
A flat panel for radiation imaging comprising:a radiation transducer to be exposed to incident radiation;an array of pixels on one side of said radiation transducer, each of said pixels including a storage capacitor to store signal charge proportional to the exposure of said radiation transducer to radiation in the vicinity of said pixels;a plurality of gate lines interconnecting the rows of pixels in said array, said gate lines receiving gate pulses to allow said pixels to be selected on a row-by-row basis;a plurality of source lines interconnecting the columns of pixels in said array to allow signal charges held by the storage capacitors of said selected pixels to be sensed, at least one pair of adjacent pixels in each row sharing a source line; andcontrol means to control selection of the pixels sharing a source line so that the signal charge stored by the storage capacitor of only one pixel of each pair can be sensed by way of a shared source line at a time when said row of pixels is selected.
