Background

The X-ray detection technology has important application in the fields of hospital patient diagnosis, industrial nondestructive detection, station safety inspection and the like. However, in the existing X-ray detection, since the dissipation speed of the thermal capacity of the tube sleeve in the X-ray tube is slower than that of the thermal capacity of the anode bulb tube, the efficiency of the X-ray tube is very low, most energy is converted into heat, the heat accumulation after a certain time can also cause the thermal capacity to exceed the limit, and when the thermal capacity exceeds the limit, the damage and the aging of the anode target surface of the X-ray tube can be caused.

In order to solve the problem of thermal capacity overrun, the existing processing method is that when the thermal capacity overrun occurs in the process of emitting X-rays by an X-ray tube, the thermal capacity protection function of a high-voltage generator is started immediately. Although the existing processing method can slow down the damage and the aging of the anode target surface of the X-ray tube, the existing processing method can only start the heat capacity protection function of the high-voltage generator to protect when the heat capacity is detected to be out of limit, and cannot early warn the possible out-of-limit situation of the heat capacity of the X-ray tube, so that certain influence can still be caused on the anode target surface of the X-ray tube in the actual application.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In addition, the method provided by the embodiment of the present application can predict the thermal capacity when the X-ray tube performs exposure and fluoroscopy requests, and make a decision to determine whether the exposure and fluoroscopy requests are allowed or not through the thermal capacity, thereby avoiding exposure and fluoroscopy stop caused by the thermal capacity overrun after the exposure and fluoroscopy start. The method provided by the embodiment of the application can be suitable for shooting and perspective modes in X-ray detection, and the operation mode for X-ray detection can also be an inner synchronization mode and an outer synchronization mode. The main difference between the inner synchronization mode and the outer synchronization mode is as follows: the effective exposure time of the internal synchronization mode can be directly set through software, namely the time length of exposure can be known accurately before fluoroscopy, namely, if the X-ray tube works in the internal synchronization working mode, the time length for stopping implementing fluoroscopy can be accurately controlled and set according to the software; the outer sync mode cannot know the specific perspective time length in advance.

For convenience of description, terms referred to in the present invention are explained as follows:

KV: tube voltage of the X-ray tube, unit: kV;

MA: tube current of the X-ray tube, unit: mA;

MS: effective exposure time of the intra-synchronous mode X-ray tube, unit: s;

MS 1: cumulative effective exposure time of the X-ray tube, unit: s;

MS 2: effective exposure time 1 of the external synchronous mode X-ray tube, unit: s;

q1: anode heat capacity of X-ray tube, unit: j;

q2: jacket heat capacity of X-ray tube, unit: j;

q1_ max: anode heat capacity of X-ray tube exceeds limit, unit: j;

q2_ max: tube jacket heat capacity of X-ray tube is over limit, unit: j;

when the MS1 is in intra-sync mode: for the shooting mode and the perspective mode, the accumulated effective exposure time must satisfy MS1 ≧ MS. In the external synchronization mode, the high voltage follows the external enable signal to generate X-rays, and the accumulated effective exposure time must satisfy that MS1 is more than or equal to MS2 for the shooting mode and the perspective mode.

Q1_ max in actual use, Q1_ max is the percentage of the maximum heat capacity of the X-ray tube anode in the data sheet, e.g., 80%.

Q2_ max in actual use, Q2_ max is the percentage of the maximum heat capacity of the X-ray tube housing in the data sheet, e.g., 80%.

In addition, referring to fig. 1, which is a block diagram of an X-ray detection apparatus, the detection method and the control method of the X-ray tube provided by the embodiment of the present invention are both applicable to the X-ray detection apparatus, wherein the structure of the X-ray detection apparatus mainly includes: x-ray tube assembly 1, high voltage generating device 2, controlling means 3, the X-ray tube assembly includes: an anode bulb and a sleeve; the high voltage generating device comprises a high voltage generator.

An embodiment of the present invention provides a detection method for an X-ray tube, as shown in fig. 2, the detection method includes:

s10, the heat capacity value and the operation parameter value of the X-ray tube are acquired.

In this embodiment, the control device obtains the heat capacity value of the X-ray tube by reading the heat capacity value of the X-ray tube and the operating time of the X-ray tube stored in the last shutdown from the memory chip after the startup initialization of the high voltage generator is completed; and secondly, reading the current time from the clock chip, and respectively reading the heat capacity value of the X-ray tube stored when the X-ray tube is shut down last time and the working time of the X-ray tube last time from the memory chip according to the current time, and obtaining the heat capacity value of the current X-ray tube through calculation. In addition, when the X-ray tube is in the initial power-on state, it may be understood that there is no case where the heat capacity value of the X-ray tube stored at the time of the previous power-off is acquired, and the acquired heat capacity value of the X-ray tube may be a value obtained by accumulating the heat capacity value of the X-ray tube from the initial time to the heat capacity value of the X-ray tube before the end of the present power-off operation, that is, it may be considered that when the X-ray tube is in the initial power-on state, the accumulated heat capacity value of the X-ray tube approximates to the predicted heat capacity value of.

The calculating of the current heat capacity value of the X-ray tube may be based on the last operating time of the X-ray tube and the heat capacity value of the X-ray tube stored at the last shutdown, and the heat capacity value of the X-ray tube is obtained by calculating an 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. Since heat capacity dissipation occurs during the operation of the heat capacity of the X-ray tube, the heat capacity dissipation value occurring during the operation of the heat capacity of the X-ray tube needs to be subtracted 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 the data sheet of the X-ray tube.

In this embodiment, the obtained operation parameter values include: time values (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.

And S11, if the heat capacity value of the X-ray tube is smaller than the preset heat capacity over-limit value of the X-ray tube, calculating the predicted heat capacity value of the X-ray tube based on the heat capacity value of the X-ray tube and the operation parameter value.

In this embodiment, the control device reads the heat capacity value of the X-ray tube and compares the heat capacity value with a preset heat capacity over-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 over-limit value of the X-ray tube, 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 are obtained to calculate the predicted value of the heat capacity of the X-ray tube.

If the exposure request is not monitored, step S45 is performed;

if an exposure request is monitored, the high voltage generator reads the exposure parameters of the current shooting mode, such as: KV, MA, MS1, MS2, and then the predicted value Δ Q of the heat capacity of the X-ray tube is calculated from the exposure parameters.

DELTA.Q < Q2_ max, the current exposure request is permitted, and step S45 is executed after the end of the exposure.

And S45, ending the exposure decision, entering S41, and starting the next exposure prediction decision.
