Disclosed is a dual array detector module adapted to radiation-imaging,
comprising: a first detector array consisting of a plurality of first
detectors and arranged on a first surface of a heavy metal plate; a
second detector array consisting of a plurality of second detectors and
arranged on a second surface of the heavy metal plate opposite to the
first surface; and a mounting frame, in which the first detector away and
the second detector array arranged on the first and second surfaces of
the heavy metal plate respectively are mounted in the mounting frame, a
housing which has a substantially elbow shape in cross-section, wherein
an electronic circuit board having an output terminal and an input
terminal is disposed inside the housing, in which the input terminal of
the electronic circuit board is connected to signal output terminals of
the first and second detector arrays and the output terminal of the
electronic circuit board is connected to a socket mounted on the housing.
