英文摘要	We have built and investigated a detector module for animal spect imaging, especially for use in large field of view (fov) conditions. the module consists of a pmt-based detector and a parallel-hole collimator with an effective area of 80 mm x 80 mm. the detector is composed of a nai scintillation crystal array coupled to four 118500 position sensitive photomultiplier tubes (ps-pmt). the intrinsic energy resolution of the detector is 11.5% at 140 kev on average. the planar spatial resolution of the module changes from 2.2 mm to 5.1 mm at different source-to-collimator distances with an unchanged sensitivity of about 34cps/mbq. additionally, the spect micro deluxe phantom imaging was performed with a radius of rotation (ror) of 40 mm. using the fbp reconstruction algorithm, a high performance image was obtained, indicating the feasibility of this detector module.
