FIELD: medicine.SUBSTANCE: invention relates to medical equipment. X-ray imaging device monitoring system comprises: X-ray imaging device comprising a suspension device, wherein the suspension device comprises an X-ray source and is suspended from the guide, wherein the suspension device is movable along the guide, and the guide has a first target position and a first control point, wherein the first control point corresponds to the first target position, the control device configured to control the suspension device, the storage device storing the set of commands for controlling the suspension device； and at least one processor configured to communicate with the storage device. When executing a set of instructions, said at least one processor is configured to cause the system to: determine a first checkpoint corresponding to the first target position on the guide, wherein the distance between the first control point and the first target position is less than a predetermined distance, obtain, during movement of the suspension device along the guide, the first speed of the suspension device in the first control point, determine whether the first speed of the suspension device at the first control point is less than the threshold speed, and in response to determining that the first speed of the suspension device at the first control point is less than the threshold speed, actuating a control device to move the suspension device to the first target position. Method for controlling an X-ray imaging device implemented in a computer device having one or more processors and one or more data media, an X-ray imaging device comprising a suspension device, wherein the suspension device comprises an X-ray source and is suspended from the guide, wherein the suspension device is movable along the guide, and the guide has a first target position and a first control point, wherein the first control point corresponds to the first target position. Method comprises: determining a firs
