Bed plate, bed comprising bed plate, and computed tomography (CT) equipment

Abstract

The invention discloses a bed plate, a bed comprising the bed plate, and computed tomography (CT) equipment. The bed plate comprises an air cushion capable of inflating or deflating, and a bed plate shell for accommodating the air cushion; the bed comprises the bed plate; and the CT equipment comprises the bed or the bed plate. The height and the inclined angle of the bed plate can be adjusted by sampling the air cushion capable of inflating or deflating, so that patients of different sizes can be positioned in the middle of an aperture of a scanning frame to acquire the clearest image; different scanning parts are positioned at proper inclined angles, so that the patients receive the minimum X-ray dose, and a mechanical device for adjusting the height and the inclined angle of the bed plate is not required; and therefore, the cost is reduced.

Description

technical field [0001] The present invention generally relates to the field of CT equipment, in particular to a bed board, a bed including the bed board, and CT equipment. Background technique [0002] Scanning with CT equipment to obtain clear images of objects to be scanned has been widely used. well known, such as figure 1 As shown, a typical CT device at least includes a tube (X-ray tube) 1, a detector 2, and a bed 3, wherein the tube 1 is used to emit X-rays; the detector 2 is used to receive the tube 1, the X-rays emitted by the display console 50 are used to image the scanned object (such as a patient); the bed 3 is used to carry the scanned object, and the bed 3 includes a bed board 31 and a driving device 32. Typically the tube 1 and detector 2 are arranged on opposite sides within the gantry. [0003] In order to target different objects to be scanned, the bed in the prior art also has a rising and falling mechanism. [0004] In addition, the scanning frame of ...

AI Technical Summary

Problems solved by technology

[0005] The bed board 31 of the bed 3 used in typical CT equipment is usually made of carbon fiber material, because carbon fiber is relatively expensive, so the cost of the whole CT equipment is relatively high

[0006] Secondly, since the bed board 31 needs to be able to carry the patient during the scanning process of the CT equipment, the sliding structure for making the bed board slide mainly includes guide rails, pulleys, etc., which is very complicated and also increases the cost of the entire CT equipment.

[0007] Moreover, since the patient is lying on the bed board 31 during the scanning process, the X-ray emitted from the ball tube 1 needs to pass through the patient and the bed board 31 to reach the detector 2. At
