Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
In addition, the method provided by the embodiment of the application can predict the heat capacity when the X-ray tube performs the exposure and perspective request, and determine whether the exposure and perspective request is allowed or not through the heat capacity, so that the exposure and perspective stop caused by the overrun of the heat capacity after the exposure and perspective start is avoided. The method provided by the embodiment of the application can be suitable for shooting and perspective modes in X-ray detection, and the running mode aimed by the X-ray detection can be an inner synchronous mode and an outer synchronous mode. The main difference between the internal synchronization mode and the external synchronization mode is that: the effective exposure time of the internal synchronization mode can be directly set by software, namely, the exposure time length can be known precisely before perspective, namely, if the X-ray tube works in the internal synchronization working mode, the time length for stopping implementing perspective can be precisely controlled according to the software setting; the external synchronization mode cannot know the specific perspective time length in advance.
For convenience of description, the terms involved in the present invention are explained as follows:
KV: tube voltage of X-ray tube, unit: a kV;
MA: tube current of X-ray tube, unit: mA;
MS: effective exposure time of the internal synchronization mode X-ray tube, unit: s, S;
MS1: cumulative effective exposure time of X-ray tube, unit: s, S;
MS2: effective exposure time 1 of the external synchronization mode X-ray tube, unit: s, S;
q1: anode heat capacity of X-ray tube, unit: j;
q2: tube-in-tube heat capacity of X-ray tube, unit: j;
q1_max: anode heat capacity of X-ray tube exceeds limit, unit: j;
q2_max: tube sleeve heat capacity of X-ray tube exceeds limit, unit: j;
when MS1 is in the internal synchronization mode: for the film shooting mode and the perspective mode, the accumulated effective exposure time must satisfy MS 1. Gtoreq.MS. In the external synchronization mode, the high voltage follows the external enabling signal to generate X-rays, and for the film shooting mode and the perspective mode, the accumulated effective exposure time must satisfy MS1 not less than MS2.
Q1_max in actual use, q1_max is a percentage, for example 80%, of the maximum heat capacity of the anode of the X-ray tube in the data book.
Q2_max is the percentage of the maximum heat capacity of the X-ray tube jacket in the data book, for example 80%, in actual use.
In addition, please refer to fig. 1, which is a block diagram of an X-ray detection device, the detection method and the control method for an X-ray tube provided in the embodiment of the present invention are both applicable to the X-ray detection device, wherein the structure of the X-ray detection device mainly includes: an X-ray tube assembly 1, a high voltage generating device 2, a control device 3, the X-ray tube assembly comprising: anode bulb and sleeve; the high voltage generating device comprises a high voltage generator.
An embodiment of the present invention provides a method for detecting an X-ray tube, as shown in fig. 2, including:
s10, acquiring a heat capacity value and an operation parameter value of the X-ray tube.
In this embodiment, the control device obtains the heat capacity value of the X-ray tube, and reads the heat capacity value of the X-ray tube stored in the last shutdown and the working time of the last X-ray tube from the memory chip after the high-voltage generator is started and initialized; and then reading the current time from the clock chip, and respectively reading the heat capacity value of the X-ray tube stored in the last shutdown and the working time of the last X-ray tube from the storage chip according to the current time and the current heat capacity value of the X-ray tube through calculation. When the X-ray tube is in the initial on state, it is understood that the heat capacity value of the X-ray tube stored at the time of the last shutdown is not acquired, and the acquired heat capacity value of the X-ray tube may be integrated from the heat capacity value of the X-ray tube at the initial time to the heat capacity value of the X-ray tube before the end of the current shutdown operation, that is, it is considered that the heat capacity integrated value of the X-ray tube is similar to the predicted heat capacity value of the X-ray tube when the X-ray tube is in the initial on state.
The calculation of the current heat capacity value of the X-ray tube may be based on the last working time of the X-ray tube and the heat capacity value of the X-ray tube stored during the last shutdown, by calculating the average heat capacity value of the X-ray tube, and then multiplying the average heat capacity value of the X-ray tube by the current time read from the clock chip to obtain the current heat capacity value of the X-ray tube. Since heat capacity dissipation occurs during the operation of the heat capacity of the X-ray tube, it is necessary to subtract the heat capacity dissipation value generated during the operation of the heat capacity of the X-ray tube when obtaining the current heat capacity value of the X-ray tube, so that the heat capacity value of the X-ray tube can be accurately obtained. Wherein the heat capacity dissipation value can be looked up by means of a data manual of the X-ray tube.
In the present embodiment, the acquired operation parameter values include: time value (e.g., time information in a clock chip), tube voltage of the X-ray tube, tube current of the X-ray tube, exposure time, etc.

In this embodiment, the control device reads the heat capacity value of the X-ray tube and compares the heat capacity value with the preset heat capacity limit value of the X-ray tube, and if the heat capacity value of the X-ray tube is smaller than the preset heat capacity limit value of the X-ray tube, obtains the tube voltage of the X-ray tube, the tube current of the X-ray tube, and the effective exposure time of the X-ray tube to calculate the heat capacity predicted value of the X-ray tube.
Specifically, the predicted value of the heat capacity of the X-ray tube is equal to the product of the tube voltage of the X-ray tube, the tube current of the X-ray tube, and the effective exposure time of the X-ray tube.
S12, calculating the heat capacity accumulated value of the X-ray tube based on the heat capacity value and the heat capacity predicted value of the X-ray tube.

S13, determining the operation state of the X-ray tube according to the heat capacity accumulated value and the preset heat capacity overrun value.
In this embodiment, the cumulative value of the heat capacity of the X-ray tube obtained in step S12 is compared with the preset heat capacity overrun value, and if the cumulative value of the heat capacity of the X-ray tube is greater than or equal to the preset heat capacity overrun value, the operation state of the X-ray tube is abnormal, and if the cumulative value of the heat capacity of the X-ray tube is less than the preset heat capacity overrun value, the operation state of the X-ray tube is normal, and the heat capacity is not overrun and falls within the normal range.
According to the detection method of the X-ray tube, the heat capacity value and the operation parameter value of the X-ray tube are obtained, under the condition that the heat capacity value of the X-ray tube is smaller than the preset heat capacity overrun value of the X-ray tube, the heat capacity predicted value of the X-ray tube is calculated, then the heat capacity accumulated value of the X-ray tube is calculated according to the heat capacity predicted value of the X-ray tube and the heat capacity value of the X-ray tube, the operation state of the X-ray tube is determined by utilizing the relation between the heat capacity accumulated value and the heat capacity overrun value, and the heat capacity of the X-ray tube is measured by detecting the operation state of the X-ray tube, so that the influence on the anode target surface of the X-ray tube caused by the overrun of the heat capacity of the X-ray tube is avoided.
Alternatively, the preset thermal capacity overrun of the X-ray tube may be a thermal capacity value obtained from measured data, or may be parameter data obtained from an X-ray tube parameter manual.
