Detector and CT imaging equipment

The invention discloses a detector and CT (Computed Tomography) imaging equipment, belongs to the technical field of X-ray equipment, and aims to solve the technical problem that the imaging range of the existing CT equipment is small. The detector comprises a detector body, the detector body is provided with a detection surface, the detection surface is internally provided with a detection area and an auxiliary area which are connected, the detection area is of an integrated structure, and the detection area is provided with a first end, a second end, a third end and a fourth end, the first end, the second end, the third end and the fourth end are located at the edge of the detection surface, and the detection surface is filled with the detection area and the auxiliary area. In addition, other parts can be arranged in the auxiliary area on the detection surface, so that the functions of the detector are richer, the area of the detection area can be reduced, the number of detection crystals is reduced, and the purpose of reducing the cost of the detector is achieved.
