ABSTRACT:
Disclosed is an arm frame structure for a radiation imaging system, comprising a first upright column, a mounting frame, and first and second collimators mounted on said first upright column, and first and second detector devices. Said first and second collimators are arranged to be symmetrical with respect to a plane therebetween to divide a ray beam emitted from a radiation source into first and second beams emitted symmetrically. Said first and second detector devices are symmetrically mounted on the mounting frame with respect to the plane P and are arranged to be far away from said first and second collimators to receive the first and second beams, respectively. This invention further provides a radiation imaging system including the arm frame structure.
