Embodiments of the present application provide a radiation detector module, a radiation detector, and an imaging device. In the radiation detector module, the number of radiation detector elements arranged in the Z direction of a circuit substrate is 4N rows or 4N+1 rows, N being an integer greater than or equal to 1. In this way, the radiation detector elements can be removed in a symmetric manner with respect to a center of the circuit substrate in the Z direction, for example, 2N rows of radiation detector elements are removed, such that the central position of the remaining radiation detector elements in the Z direction remains unchanged. Therefore, neither the positions of the remaining radiation detector elements nor the focus position of an X-ray source requires adjustment. Thus, no change of a gantry structure is required, and additional mechanical vibration is not caused, thereby ensuring imaging quality.
A radiation detector module, used to detect a ray signal passing through a subject under examination in an imaging device, the subject under examination entering or exiting the imaging device in a first direction, wherein the radiation detector module comprises:
A radiation detector, wherein the radiation detector comprises a guide rail and two or more radiation detector modules, wherein each radiation detector module includes:
An imaging device, wherein the imaging device comprises a scanning space for accommodating a subject under examination, the subject under examination enters or exits the scanning space in a first direction, the imaging device comprises a radiation detector, and an image reconstruction apparatus, wherein the radiation detector includes
