Summary:A collimator (10) for a detector (600) is disclosed. The collimator (10) comprises: a bottom plate (100) provided with imaging through holes (110) distributed in an array, each of the imaging through holes (110) comprising a first hole segment (111) and a second hole segment (112), the transverse size of the first hole segment (111) gradually decreasing in a direction from a free end to the second hole segment (112), and the transverse size of the second hole segment (112) gradually decreasing in a direction from the free end to the first hole segment (111); a shielding ring (200) formed on the bottom plate (100); and a top plate (300) disposed in the shielding ring (200) and closing at least a part of an opening of the shielding ring (200), the top plate (300) being provided with shielding through holes (310) distributed in an array, and the imaging through holes (110) being in one-to-one correspondence with the shielding through holes (310).
