Embodiment 1

[0039] Such as image 3 and Figure 4 As shown, in the first specific implementation manner, the trolley 2 can be equipped with an emission source device to form an emission source mechanism.

[0040] The driving device can also include a first transmission gear 18 and a second transmission gear 20 meshing with each other, the first transmission gear 18 can be fixedly connected to the drive shaft 13, and can rotate with the rotation of the drive shaft 13, the second drive gear 20 and The first sensor 21 is connected, then when the drive shaft 13 rotates, the first transmission gear 18 and the second transmission gear 20 rotate thereupon, and then the driving signal of the drive shaft 13 is transmitted to the first sensor 21, so that the first sensor 21 detects the drive signal.

[0041] The first sensor 21 can specifically be a rotary potentiometer, and the input shaft of the rotary potentiometer can be connected to the second transmission gear 20, or the second transmission...

Embodiment 2

[0066] Such as Figure 5 and Figure 6 As shown, in the second specific embodiment, the trolley 2 can be equipped with a receiving detector device to form a receiving detector mechanism.

[0067] The difference from Embodiment 1 is that when the receiving detector device is installed on the trolley 2, the brake provided on the drive shaft 13 in the driving device is specifically a de-energized electromagnetic brake 23, and other parts can be set with reference to Embodiment 1.

[0068] Taking the flat panel detector as the receiving detector device as an example, the torque generated by the braking force of the de-energized electromagnetic brake 23 is greater than the torque generated by the weight of the flat panel detector itself. When the film box of the column 1 is at rest, the power-off electromagnetic brake 23 is powered off, and the turntable and the support 14 are attracted and braked to limit the rotation of the rotating shaft; no matter whether the flat panel detect...

Abstract

The invention provides a medical image system, a drive device and a drive fault detection method, for improving the safe reliability of the drive operation. The drive device comprises a pulley used for mounting an emission source device or a receiving detector device, a drive part used for driving the pulley to move, a first sensor used for detecting a drive signal of the drive part, and a second sensor used for detecting a moving signal of the pulley. Whether a drive fault exists or not can be judged according to the fact that whether the drive signal and the moving signal satisfy the corresponding relationship or not. The drive fault detection method comprises the following steps: detecting the drive signal of the drive part, and the moving signal of the pulley used for mounting the emission source device or the receiving detector device; and judging that whether the drive fault exists or not according to the fact that whether the drive signal and the moving signal satisfy the corresponding relationship or not.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical imaging system, a driving device thereof, and a driving fault detection method. Background technique [0002] The radiation emitted by the medical imaging system passes through the human body through the emitting source device and irradiates the receiving detector device, and forms an image through photoelectric conversion, which is used for the doctor's diagnosis. [0003] The emission source device usually uses a tube assembly, and the receiving detector device usually uses a flat panel detector. The medical imaging system includes a column frame for installing the tube assembly or the flat panel detector. In order to meet the requirements of use, such as standing shooting for people of different heights, or shooting in bed for different parts, it is especially necessary to adjust the height of the tube assembly and the flat panel detector synchronously when s...
