The present invention relates to a radiation detector (1000) comprising: two substrates (1100), wherein each substrate of the two substrates comprises a sensor (1110), wherein each sensor comprises an electronic array circuit (1112), which comprises an array of data read-out pixels (DRP) and which is configured to acquire image data resulting from exposure to radiation, the image data provided in a matrix data structure corresponding to the array of data read-out pixels; wherein each sensor comprises an array of electronic pixel circuits (1114), wherein each electronic pixel circuit is assigned to at least one pixel of the array of data read-out pixels; wherein each electronic pixel circuit (1114) comprises: an array of allocated signal elements (1114-SE); and a corresponding array of allocated radiation conversion elements (1114-RCE); wherein each allocated signal element together with one corresponding allocated radiation conversion element form one subpixel (SP); wherein each electronic pixel circuit (1114) is configured to receive subpixel data signals from each allocated signal element of the array of allocated signal elements to generate pixel data; wherein the electronic array circuit is configured to receive the pixel data from each electronic pixel circuit in order to acquire the image data; and wherein both sensors are at least partially facing each other at equidistance.
