The invention discloses a novel X-ray CT scanner. The scanner comprises a base, a control switch is mounted on the right side of the base, the front and rear ends of the base are both provided with a telescopic rod, the end of the telescopic rod is fixed with a top seat, an electric telescopic rod is arranged between the top seat and the base, and the upper and lower ends of the electric telescopic rods are fixedly connected with the top seat and the base respectively. The novel X-ray CT scanner has the advantages of being simple in structure, exposing only the part requiring examination to the irradiation scope of the X-ray, avoiding the radiation hazards of the X-ray to the rest of the body parts when a CT examination is conducted, and further reducing the radiation harm of the X-ray to the human body, a shield plate slides horizontally relative to a bed board, the shield plate slides relative to the scanner in the vertical direction, so that the shield plate and the lifting of the bed board are kept consistent, the shielding effect is not affected, the arrangement of elastic bands and a shielding cloth facilitates the adjustment according to the fatness and thinness of a patient, applicability is improved, the shielding effect is enhanced, and the novel X-ray CT scanner is more convenient to use.
