The present invention relates to a radiation sensor device (20) for detection of radiation. A sensor device with an array of radiation sensitive elements (24) forming a sensor surface (26) is provided. The device comprises a number of circuit boards (21), each with a row of radiation sensitive elements, such as X-ray sensitive charge collectors, provided at the edge portion. The radiation sensitive elements are each connected to signal processing means (28), e.g. ASICs with amplifiers, outside the radiation field by a respective connection line (25) arranged on a main surface (22) of the circuit board. A number of circuit boards are arranged adjacent to each other with the main planes substantially perpendicular to the sensor surface. By using the circuit card depth the invention easily provides surfaces with a very large number of individually connected radiation sensitive elements, resulting in improved image resolution.
