Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an X-ray imaging apparatus.

[0002]

2. Description of the Related Art An X-ray image capturing apparatus has, for example, a focus size of 1.
The X-ray generation means has an X-ray generation tube of mm or less, and the imaging means has a film or an imaging plate (IP). At the time of image capturing, the subject, who is the subject, is placed between the X-ray generation means and the imaging means. The X-rays generated by the X-ray generation means pass through the body of the subject to reach the photographing means, and the film or imaging plate provided in the photographing means is exposed to light to be used for the diagnosis of the subject. An image is formed.

[0003]

When photographing an image with X-rays, it is desirable that the X-ray generating means and the photographing means are completely stationary. However, in reality, the positional relationship between the X-ray generating means and the photographing means changes during the photographing of the image due to the vibration generated at the time of photographing the image, resulting in blurring of the photographed image, and the diagnosis using the image is performed. The accuracy of the image may be lost and the image diagnosis may be hindered.

The vibration that blurs the photographed image is generated when the body of the subject or a care tool used by the subject touches the photographing means or the operator touches the X-ray generating means. There is vibration. Other vibrations include vibrations caused by devices and the like arranged around the X-ray imaging apparatus, and minute vibrations derived from the structure of the building in which the X-ray imaging apparatus is installed and location conditions.

In order to suppress blurring caused by the vibration of the X-ray generating means or the photographing means, the X-ray generating means and the photographing means are respectively supported by vibration suppressing materials such as vibration damping rubbers, so that the X vibration is controlled by passive vibration control. A method of removing the vibrations of the line generating means and the photographing means is generally practiced. With this method, vibrations with a relatively large amplitude can be removed, but minute vibrations that cannot be detected or predicted by the operator cannot be removed.

Further, as a method of preventing the blurring of the image, there is a method of increasing the focal dimension of the X-ray generating tube. In this case, however, the sharpness of the photographed image is lowered, so that the X-ray image photographing is also performed. The accuracy of the diagnosis using the image taken by the device is reduced.

In order to solve the above-mentioned problems, the present invention is an X-ray image radiographing method capable of radiographing an image having a degree of clarity which enables accurate image diagnosis without being affected by vibrations of the X-ray generating means and the radiographing means. The purpose is to provide a device.

Next, the X-ray imaging apparatus 10 according to the present invention.
The vibration control at 0 will be described.

When the X-ray generation means 1 vibrates, the generation side vibration sensor 131 detects this vibration and transmits it to the control means 5. The control unit 5 stores the time-series vibration data transmitted from the generation-side vibration sensor 131 as the vibration history in the non-volatile memory 54, and the vibration data and RO.
Based on the data stored in M52, the CPU 51 performs calculation and determination to determine the control method of the generating side actuator 132.

The position and attitude of the robot are controlled to be almost constant. By controlling the generation side actuator 132 in this way, the vibration of the X-ray generation means 1 is suppressed.

When the photographing means 2 vibrates, the photographing side vibration sensor 231 detects this vibration and transmits the vibration data to the control means 5. At this time, the control means 5 stores the vibration data in the non-volatile memory 54 as a vibration history of a time series that coincides with the time series of image capturing in the same manner as when the X-ray generation means 1 vibrates, and the vibration data is stored in the vibration data. On the basis of this, by operating the photographing side actuator 232 so as to cancel the vibration of the photographing means 2, the position and posture of the photographing means 2 are controlled to be substantially constant. By controlling the photographing side actuator 232 in this way, the vibration of the photographing means 2 can be suppressed.

Here, the amplitude of the vibration detected by the vibration sensor 131 on the generating side and the vibration sensor 231 on the photographing side is effectively controlled by the actuator 132 on the generating side and the actuator 232 on the photographing side as described above. Means 2

Prohibit the generation of X-rays by 2. At this time, a display notifying that X-ray generation is prohibited is displayed on the control panel (not shown).

The vibration data transmitted by the vibration sensor 131 on the generating side and the vibration sensor 231 on the photographing side and the control means 5 are used.
The method of controlling the generation-side actuator 132 and the imaging-side actuator 232 is based on experiments, test results, and the experience of a radiologist, and is accurate enough to allow the X-ray imaging apparatus 100 to capture an image with clarity that can be practically used. The positions and orientations of the X-ray generation means 1 and the imaging means 2 are appropriately determined so that they can be kept constant. Further, the control means 5 uses the X-ray generation means 1
Also, in order to effectively suppress the vibration of the photographing means 2, a program for appropriately learning the control method of the generation side actuator 132 and the photographing side actuator 232 is RO.
It may be stored in M52.

As described above, the generation side actuator 132 and the photographing side actuator 232, which are vibration control means, are driven based on the vibration data detected by the generation side vibration sensor 131 and the photographing side vibration sensor 231 which are vibration detecting means. By actively controlling the vibrations of the ray generating means 1 and the photographing means 2, it is possible to photograph a clear X-ray image that enables accurate image diagnosis by the X-ray image photographing apparatus 100 regardless of external conditions. it can.

That is, the generation side actuator 132 and the photographing side actuator 232 are operated to control the positions and postures of the X-ray generation means 1 and the photographing means 2 to be substantially constant, whereby the X-ray generation means 1 and the photographing means 2 are connected. The relative position and orientation of can be kept almost constant throughout the image capturing. Therefore, blurring of an image caused by a change in the positional relationship between the X-ray generation unit 1 and the imaging unit 2 during image capturing is suppressed, and accurate diagnosis can be performed on the resulting image. Clarity can be imparted.

Further, when the vibration sensor 131 on the generating side and the vibration sensor 231 on the photographing side detect a vibration having an amplitude equal to or more than a predetermined amount, the generation of X-rays by the X-ray generating means 1 is prohibited, so that It is possible to prevent unnecessary X-ray exposure of the subject 500, which is a sample, and reduce the risk of the subject 500 from image diagnosis.

That is, the vibrations of the X-ray generating means 1 and the photographing means 2 are extremely large, and when an image is photographed in a state where this vibration cannot be effectively controlled by the generating side actuator 132 and the photographing side actuator 232, an image obtained is obtained. Since the flash is so remarkable that an accurate diagnosis cannot be made, it is necessary to take an image again.
Therefore, it is possible to avoid capturing an unnecessary X-ray image by making it impossible to capture an image with significant blur as described above.

Further, the vibration data detected by the vibration sensor 131 on the generating side and the vibration sensor 231 on the photographing side are stored in the non-volatile memory 54 as a vibration history of a time series which coincides with the time series of the image shooting, whereby X-ray image shooting is performed. Diagnosis using the image captured by the apparatus 100 can be accurately performed. That is, when a doctor has a doubt about this image when making a diagnosis with the image obtained by the X-ray imaging apparatus 100, the vibration history is referred to and the image diagnosis is continued or the X-ray image It is possible to appropriately make a determination as to whether the image is appropriate or not, such as whether to retake the image. As a result, accurate diagnosis can be performed using the image. In addition, the image is stored in a computer for analysis,
When the processing is performed, more accurate image diagnosis can be performed by correcting the image using the vibration history.

The X-ray imaging apparatus 10 according to the present invention.
0 is not limited to the above. For example, based on the vibration data of the X-ray generation unit 1 detected by the generation-side vibration sensor 131, the control unit 5 controls the imaging-side actuator 232 and causes the imaging unit 2 to vibrate in conjunction with the X-ray generation unit 1. Good.

At this time, the photographing side actuator 232
Controls the vibration of the photographing means 2 so that the relative position and orientation of the X-ray generation means 1 and the photographing means 2 are kept substantially constant as a result of the vibration of the photographing means 2. Even in this case, the blurring of the image is prevented as in the case where the vibrations are controlled so that the respective positions and orientations of the X-ray generation means 1 and the imaging means 2 are constant as described above, and accurate image diagnosis is performed. Images can be obtained with as much clarity as can be done.

Further, the control means 5 controls the generating side actuator 132 based on the vibration data of the photographing means 2 detected by the photographing side vibration sensor 231, and vibrates the X-ray generating means 1 in conjunction with the photographing means 2. May be In this way, which of the X-ray generating means 1 and the photographing means 2 is linked with the other is, for example, which of the X-ray generating means 1 and the photographing means 2 is located on the upstream side near the cause of vibration. Decide in consideration of factors.

0 may not include the generating side actuator 132 and the photographing side actuator 232, or may include the generating side actuator 132 and the photographing side actuator 232 but not operate. In this case, when the generation-side vibration sensor 131 or the imaging-side vibration sensor 231 detects a vibration having an amplitude equal to or larger than a predetermined value, the control unit 5 prohibits the X-ray generation by the X-ray generation unit 1 and any operation by the operator. Even if the above is performed, the X-ray generation means 1 is prevented from generating X-rays. Here, the predetermined value is set so that the blurring of the image caused by the vibration of the X-ray generating means 1 and the imaging means 2 does not detract from the accuracy of the diagnosis using the above-mentioned image. It will be decided appropriately based on experience.

As a result, it is possible to prevent a situation in which an image with significant blurring is obtained and the accuracy of image diagnosis is deteriorated due to the use of this image, and it is possible to avoid re-taking the X-ray image. .

The installation positions and installation forms of these vibration detection means and vibration control means are design matters, and are appropriately determined so that the positions and orientations of the X-ray generation means 1 and the imaging means 2 can be effectively controlled.

Therefore, for example, the generation side vibration sensor 131
