Abstract

The present invention discloses a solid state detector module structure, comprising: an upper support plate and a lower support plate provided opposing to each other, a collimator provided between the upper support plate and the lower support plate for collimating the incident rays; and solid state detector arrays provided between the upper support plate and the lower support plate at the rear side of the collimator in the transmitting direction of the rays, wherein the solid state detector arrays comprises an upper and lower rows, with the upper row of the solid state detector array fixed under the upper support plate, and the lower row thereof fixed on the lower support plate. The present invention further discloses a radiation imaging system having the same. The solid state detector module structure of present invention decreases the scattering of ray beams, increases the capabilities of scattering resistance and the definition of image and enhances inspection speed compared with prior art.
