Problems solved by technology

[0005] The lifting of the bed body of the CT double push rod scanning bed depends on the sliding of two push rods on the slide rail of the base. The positioning accuracy of the current CT double push rod scanning bed in the vertical direction is not high enough during the lifting process, and the uniformity of the lifting speed is not enough. Well, there are security and reliability issues

Abstract

The invention relates to a CT scanning bed lifting control system, a CT scanning bed and a control method. The system comprises a control unit, a push rod driving motor set, a speed measurement sensorset and a height sensor, wherein the push rod driving motor set, the speed measurement sensor set and the height sensor are connected to the control unit. The push rod driving motor set comprises a first push rod driving motor connected to a first push rod and a second push rod driving motor connected to a second push rod, the speed measurement sensor set comprises a first speed measurement sensor connected to a rotating shaft of the first push rod driving motor and a second speed measurement sensor connected to a rotating shaft of the second push rod driving motor, and the height sensor is used for acquiring actual height data of a bed body. Compared with the prior art, the control precision is high, the reliability is high, and the safety is high.

Description

technical field [0001] The invention relates to the field of CT double-push-rod scanning beds, in particular to a CT scanning bed lifting control system, a CT scanning bed and a control method. Background technique [0002] In the CT equipment, a scanning bed will be configured. During the scanning process, the patient will lie on the scanning bed and maintain a corresponding posture for CT scanning. The scanning table needs to have a certain range of lifting function, mainly because of the following two factors: [0003] The scanning field of view in the CT scanning gantry is determined by the gantry aperture. The center of the gantry aperture has a certain distance from the horizontal plane of the gantry installation. image quality. Because the patient's physical condition and scanning posture are different, after the patient lies on the scanning bed, the height of the bed needs to be fine-tuned to achieve the best scanning state. [0004] In addition, the patient needs...
