As shown in fig. 1, the method for controlling tube voltage of an X-ray tube according to an embodiment of the present invention includes the following steps:

s1, the tube voltage value set by the X-ray tube and the preset tube voltage value are acquired.

Specifically, the set tube voltage value of the X-ray tube may be automatically recorded, and the preset tube voltage value may be input by an operator. Wherein if the tube voltage of the X-ray tube is set for the first time, the tube voltage value already set in the X-ray tube may be considered as zero.

And S2, judging whether the preset tube voltage value exceeds the tube voltage threshold value.

Specifically, the tube voltage threshold may be 200KV, and whether the preset tube voltage value exceeds the tube voltage threshold, that is, whether the preset tube voltage value exceeds 200KV may be determined by comparing the preset tube voltage value with the tube voltage threshold.

S3, if the preset tube voltage value does not exceed the tube voltage threshold, it is determined whether the preset tube voltage value exceeds the set tube voltage value.

It should be understood that no adjustment of the X-ray tube voltage is required when the preset tube voltage value is equal to the set tube voltage value, and the following description is not provided for the case where the preset tube voltage value is equal to the set tube voltage value.

More specifically, as shown in fig. 2 (for convenience of description, the preset tube voltage value may be set as a, the preset tube voltage value may be set as b, and the tube voltage threshold may be 200KV), when the preset tube voltage value does not exceed the tube voltage threshold (b ≦ 200KV), if the preset tube voltage value exceeds the preset tube voltage value (b > a), the tube voltage of the X-ray tube is controlled to increase by 1KV (a ═ a +1, Time ═ 10ms) every 10ms from the set tube voltage value until the preset tube voltage value is increased; when the preset tube voltage value does not exceed the tube voltage threshold value (b is less than or equal to 200KV), if the preset tube voltage value does not exceed the set tube voltage value (b is less than a), the tube voltage of the X-ray tube is controlled to be reduced by 1KV (a is a-1, and Time is 5ms) every 5ms from the set tube voltage value until the tube voltage value is reduced to the preset tube voltage value.
