rows r1 r2 r3 r4 rn and in columns c1 c2 cn i cn 2 cn 1 cn the stored charges are proportional to the intensity of the radiation intensity incident on each sensor 10a 10n and to reconstruct an image the stored charges are read out sequentially using either a programmed computer a cpu or a timing circuit to control a plurality of multiplexing circuits as is well known in the art in operation a voltage is applied to the panel through programmable power supply 44 controlled from control circuit 42 and the panel is exposed to the desired event i e image wise modulated x ray radiation resulting in a plurality of stored charges in the plurality of capacitors 14 for each element as seen in fig2 all detection elements 10a 10n have their capacitors 14 connected through switches 15 in columns c1 etc through lines 18a 18n each line terminating in a read out module 20 which operates in the manner described above with respect to the single element of fig1 similarly all gates 16 of fet switches 15 of all elements in each row r1 r2 rm are connected to a gate address line 17a 17m and all gate address lines are connected to multiplexing circuit 46 which is controlled from control circuit 42 control circuit 42 through multiplex circuit 46.
