Problems solved by technology

However, there are some disadvantages in this method, mainly because the size of the projection image of the detection object and the detection plate cannot be well matched. When detecting small objects, the detection plate cannot give full play to the advantages of detection accuracy.
For example, in animal diagnosis and treatment, it is necessary to meet the scanning requirements of animals of different sizes at the same time. In this application scenario, the current conventional CBCT cannot well meet the requirements.

Abstract

The invention discloses a CBCT acquisition device for animals with different body types. The CBCT acquisition device comprises a guide rail, a supporting frame is arranged below the guide rail, a flat panel detector and an X-ray bulb tube are respectively mounted at the two ends of the guide rail, a reflective film is arranged on the front side of the X-ray bulb tube, the reflective film is connected with the guide rail through a support, a sliding block is arranged on the guide rail, the sliding block is slidably connected with a sliding groove, the sliding groove is formed in the bottom of the detection table, the bottom of the detection table is connected with a rotating motor through an electric telescopic rotating shaft, the side face of the detection table is connected with a sliding motor through a telescopic rod, the sliding motor is fixed to the guide rail, and the rotating motor and the supporting plate are both located in the supporting frame. The rotating motor, the sliding motor and the electric telescopic rotating shaft are connected with a controller. According to the device, the detection size of the flat plate detector can be fully utilized so that the scanned image information is richer, and the detection flat plate can fully exert the advantage of detection precision when a smaller object is detected.

Description

technical field [0001] The invention relates to the technical field of CBCT collection devices, in particular to a CBCT collection device and a collection method for animals of different sizes. Background technique [0002] CBCT refers to Cone beam CT, which is a cone beam projection computerized reconstruction tomography imaging device. Its principle is that the X-ray generator performs circular digital projection around the projection body with a low amount of radiation. Then the data obtained in the "intersection" after multiple digital projections around the projection body are "reconstructed" in the computer to obtain a three-dimensional image. Because of its flexible rack system, cone-beam CT can freely rotate in multiple directions, and has more application scenarios that traditional fan-beam CT does not have. At present, in clinical practice, the object to be detected is placed on the rotation center of the system, and then the X-ray tube and the detection plate rot...
