Abstract

It is intended to provide an X-ray photography apparatus whereby lungs can be photographed in the desirable inherent size thereof.

An X-ray photography apparatus, having: an X-ray radiation section for radiating an X-ray; an imaging section for detecting the X-ray having passed through an examinee; a memory section for storing maximum inspiration amount data of the examinee; an aspiration flow amount measuring section for measuring an aspiration flow amount of the examinee; and a control section for conducting data processing based on the maximum inspiration amount data of the examinee stored in the memory section and the aspiration flow amount of the examinee measured by the aspiration flow amount measuring section.

Claims

1. An X-ray photography apparatus, comprising:

an X-ray generation section for radiating an X-ray;

an imaging section for detecting the X-ray having passed through an examinee;

a memory section for storing maximum inspiration amount data of the examinee;

an aspiration flow amount measuring section for measuring an aspiration flow amount of the examinee; and

a control section for conducting data processing based on the maximum inspiration amount data of the examinee stored in the memory section and the aspiration flow amount of the examinee measured by the aspiration flow amount measuring section.

2. The X-ray photographing apparatus of claim 1, further comprising:

a display section;

wherein the control section displays a target inspiration amount based on the maximum inspiration amount data of the examinee stored in the memory section and the aspiration flow amount of the examinee measured by the aspiration flow amount measuring section on the display section.

3. The X-ray photographing apparatus of claim 1, wherein the control section allows radiation of the X-ray by the X-ray generation section in case the aspiration flow amount of the examinee measured by the aspiration flow amount measuring section is not less than the target inspiration amount based on the maximum inspiration amount data stored in the memory section.

4. The X-ray photographing apparatus of claim 3, wherein the control section allows radiation of the X-ray by the X-ray generation section in case a fluctuation of the aspiration flow amount of the examinee measured by the aspiration flow amount measuring section is not more than a predetermined value.

5. The X-ray photographing apparatus of claim 2, wherein an inspiration amount upper limit based on the maximum inspiration amount data of the examinee stored in the memory section is displayed on the display section.

6. The X-ray photographing apparatus of claim 5, wherein the control section allows radiation of the X-ray by the X-ray generation section in case the aspiration flow amount of the examinee measured by the aspiration flow amount measuring section is not less than the target inspiration amount based on the maximum inspiration amount data stored in the memory section, and is not more than the inspiration amount upper limit based on the maximum inspiration amount data of the examinee stored in the memory section.

7. The X-ray photographing apparatus of claim 1, further comprising:

a tubal substance in which aspiration air flows;

a movable member, disposed in the tubal substance in a direction to block a flow of the aspiration air partially or totally, which physically changes in accordance with a flow amount of the aspiration air; and

a detection device, disposed outside the tubal substance, for detecting an amount of physical change of the movable member in a non-contact manner.
