Abstract

PURPOSE:To read out the memorized cooling data to an X-ray control portion and to control the heat radiation of an X-ray tube on the basis of the data by inputting the data by means of a selection switch when writing in the cooling characteristic data and protecting them even when a power supply is cut off. CONSTITUTION:When a switch 3' is operated, display data are written into a memory 4 through a bus line. The contents or the data of the memory 4 are protected in the memory contents even when a power supply is cut off by means of a battery or a protection circuit 5 for the memory contents. Next, by the operation of a selection switch 2, the X-ray device 1 can be used for the usual medical treatment. In this case, the switches 3 and a data display portion 7 are, respectively, used to set the condition of radiation of the X-rays and to display it. An X-ray control portion 6 perceives the condition of load which has been applied to an X-ray tube 8 and can require the quantity of heat which is stored in the X-ray tube 8 and further reads out the characteristic data from the memory 4 and carry out the control of the heat radiation on the basis of the data when the X-rays are not radiated.

Description

[Detailed description of the invention] (b) Industrial application fields INDUSTRIAL APPLICATION This invention is utilized in the field of an X-ray apparatus.

The present invention relates to an X-ray device to which % types of X-ray tubes can be connected.

(b) Prior Art In the past, there were no major changes in the cooling characteristics, which are the basic characteristics of X-ray tubes. Therefore, it was sufficient to store typical cooling characteristics as fixed data in a read-only memory (ROM). At the cost of tonight's accuracy, x
The heat radiation management of the m-tube was carried out without any problems.

(c) Problems to be Solved by the Invention However, as the technology of X-ray tubes has improved, X-ray tubes having various characteristics have been developed. Accordingly, in the medical field, highly accurate protection is required for each X-ray tube having different characteristics. In other words, the conventional X-ray tube protection function using fixed representative cooling data is no longer able to provide adequate protection.

The purpose of the present invention is to manage heat radiation for all medical X-ray tubes that currently exist or will be newly developed in the future.In other words, each time a new X-ray tube is used, its cooling characteristics are An object of the present invention is to provide a medical X-ray device that can write, store, and read data.

(d) Means for Solving the Problems The purpose of the invention or solution to the above N points is to solve the problem when using a memory that retains data even when the power is turned off, and an XFA tube with different cooling characteristics. An input means that allows the cooling characteristic data to be written into the memory, and input of the cooling characteristic data. ! The switch preferably includes a switch for selecting whether to use the X-ray tube, so that when the X-ray tube is used after writing the cooling characteristic data into the memory, the cooling characteristic data in the memory is read out to the X-ray controller. This is achieved through black computer control.

(e) When writing the cooling characteristic data of a newly used X-ray tube into the read/write memory, input the data using the selection switch. In this case, the data is protected even when the power is turned off. Therefore, even in normal medical practice, the stored cooling data is read out to the X-ray control section by the selection switch, and heat radiation management of the X-ray tube is performed based on the data.

(·\)Example A preferred embodiment of the invention will be explained based on the drawings.

The drawing is an explanatory view of the main parts of one embodiment of the invention. The upper part shows data input and its display appearance, the lower part shows a data processing block diagram, and the right part shows an example of connection with the xtA pipe. ing.

According to the present invention, when a new X-ray tube is used, its cooling characteristics are written and then the X&9!
It has a release switch 2 for use when medical treatment is performed using a tube.

When you clear the cooling characteristic writing state with switch 2, another switch! By sweeping I3, the data to be written is displayed on the upper display section 7, respectively.

According to the illustrated example, 100 KV is displayed by the switch 3a, 500 mA by the switch 3b, and 10 msec by the switch 3c.

These numbers are not directly related to the respective units, but represent the maximum accumulated ripeness, the accumulated ripeness after the cooling time, and the cooling time.

Therefore, if there is not much display data, switch 3'
When sweeping, the display data is transferred to memory 4 via the pass line.
written to. The stored contents of the memory 4 and the data are protected by the battery or the stored contents protection circuit 5 even when the power is turned off.

In addition, 6 is an X-ray control unit, 8 is an X-ray tube, 9 is a CPU, 11
is a high voltage generator.

The CPU 9 controls writing of the cooling data described above and successive output of data in the memory 4 of the X-ray control unit 6-, which will be described later.

Next, by sweeping the selection switch 2, the X-ray apparatus 1 can be used for normal medical practice. In this case, the switches 3 and data display section 7 are each
Used to set the line radiation condition and display it. The X-ray control unit 6 knows the load state applied to the X-ray tube 8 and can determine the amount of heat accumulated in the X-ray tube 8.

Furthermore, this IL control unit 6 reads characteristic data from the memory 4 and performs heat radiation management based on this data when X-rays are not being emitted. stop its use.

Note that in actual heat radiation management, arithmetic capabilities are required, and although specific hardware may be provided, software may also be used. In the illustrated embodiment, the CPU 9
Since the latter is used, the switch 2, switches 3, memory 4, X-ray control section 6, data display section 7
is connected as a peripheral device of CPU9.

Further, the control unit 6 and the CPU 9 can be made into one component.

(g) Effects With the X-ray apparatus according to the present invention, data can be easily written while looking at the cooling characteristic table of the X-ray tube, and this makes it easy not only in the shipping factory but also in the medical field. Highly accurate heat radiation management is carried out for X-ray tubes regardless of their characteristics, allowing them to be used for a long time, making full use of their capabilities, and improving image quality. This has the effect of eliminating unnecessary waiting time.
