The utility model relates to a dual array detector module structure for radiation imaging, which belongs to the technical field of the radiating detection. The utility model comprises a casing, wherein a bracket is arranged in the casing to fix two electronic circuit boards. The front end surface of the casing is provided with various sockets connected with the output ends of the two electronic circuit boards, and the bottom end of the casing is fixed with a bottom board. The bottom board is provided with an upper and a lower layer boards formed by installing frames, and the upper and the lower layer boards have the property of printed circuit boards. An upper and a lower rows of uniformly distributed detector arrays are arranged in the installing frames, and are respectively fixed with the upper and the lower layer boards of the installing frames. Heavy metal sheets having the function of crosstalk action reduction are arranged between each row of the detector arrays, and between each detector of each row of the detector arrays. Lead coats having the function of scattering action reduction are arranged between the installing frames and the periphery of each row of the detector arrays, and the signal exporting ends of each row of the detector arrays are respectively connected with the input ends of the two electronic circuit boards. The utility model has the advantage that large economic benefit can be obtained through only small investment addition and structural improvement. The utility model has the characteristics of simple structure, and convenient installation, operation and maintenance.
