DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray control system for controlling an X-ray tube for irradiating a subject with X-rays in order to perform X-ray imaging in accordance with a doctor's X-ray imaging request form. The present invention relates to an apparatus, and more particularly to a technique for controlling an X-ray tube or the like according to control conditions stored in advance.

[0002]

2. Description of the Related Art In a hospital, when a doctor examines a patient and, as a result, requires X-ray imaging, the doctor sends an X-ray imaging request sheet to the radiology department in which an imaging region and an imaging type (imaging content) are described. . In the radiology department, an appropriate type of imaging technique and an imaging type in the imaging technique are selected and determined according to an X-ray imaging request from a doctor. For example, if the imaging region is the chest and the imaging content is in three directions, the standing-book type is selected as the imaging technique, and front imaging, side imaging, and oblique imaging are selected as imaging types. Then, an X-ray control device provided in the operation room controls an X-ray tube for irradiating the patient with X-rays and executes X-ray imaging according to control conditions according to the selected imaging region and imaging type. Will be.

[0003] In the case of a conventional X-ray control device, as shown in FIG.
An operation method selection key unit 71 for selecting a type of imaging method such as a standing-up type, and a preset key unit 72 for selecting imaging conditions (tube voltage and tube current of the X-ray tube) for the imaging type are provided. I have. On the other hand, an X-ray equipped with an X-ray tube and a film holder necessary for performing the selected imaging technique is provided in the imaging room.
A radiographic device is installed, and usually, a plurality of types of X-ray radiographic devices are provided. And in the X-ray controller,
The control conditions such as the X-ray tube selection and the X-ray conditions according to the imaging type stored in advance are read in accordance with the push operation of the keys of the surgical operation selection key unit 71 and the preset key unit 72. I have.

[0004] In the case of imaging in the three directions of the chest, a patient is set up at a predetermined imaging position in an imaging room, and an unphotographed film is loaded into a film holder. Further, in the operation room, when the operator presses a key for designating standing-up photography in the keys of the surgical operation selection key section 71, and then presses a key for designating frontal photography in the preset key section 72, the photographing is performed. When preparations are started and it is notified that preparations for shooting have been completed,
A hand key (not shown) is pressed. Then, X-rays are emitted from the X-ray tube, an X-ray fluoroscopic image is recorded on the film, and the front photographing is completed.

[0005] Next, after the patient at the imaging position is set in a direction required for side imaging, the same operation as above is repeatedly performed, and the side imaging is completed. Subsequently, after the patient at the imaging position is set in a direction required for oblique imaging, the same operation as above is repeatedly performed. When oblique imaging is completed, all X-ray imaging ends. After the photographed film is subjected to necessary processing such as development, it is delivered to a doctor to be used for diagnosis. Note that this X-ray control apparatus is a general-purpose type (general-purpose type) including an imaging condition display unit 74 in which imaging conditions of only one imaging type during imaging are displayed. The shooting conditions are not displayed in a list at the same time. As described above, only the imaging conditions of the type of imaging that is being performed are displayed, because a low-priced X-ray control device is required in the case of a popular X-ray control device.

[0006]

However, in the case of the above-mentioned conventional X-ray control device, there is a problem that it is not always easy to set the imaging conditions according to the imaging mode of the doctor's X-ray imaging request sheet. In the case of X-ray imaging using a conventional apparatus, there is an annoyance that the operation of pressing the key of the preset key section 72 must be repeated every time one type of imaging is completed. Also, since the shooting condition display unit 73 only shows the shooting conditions of only the type of shooting that is being performed, it is difficult to grasp the shooting progress. Therefore, always pay attention to the shooting progress as to how far the shooting has progressed. There must be.

[0007] It is also practiced to list the photographing conditions of the photographing technique and the series of photographing types in the vicinity of the X-ray controller so as to make it easier to grasp the photographing progress. When the number of patients is large, checking the list one by one causes another problem that the imaging efficiency is deteriorated.

The present invention has been made in view of the above circumstances,
It is an object of the present invention to provide an X-ray control apparatus that can easily set control conditions according to a radiographing request photographing mode.

[0009]

In order to achieve the above-mentioned object, the present invention relates to a control system in which a pre-stored control is performed so that an X-ray image of an imaging mode described in a doctor's X-ray imaging request is performed.

Control condition reading means for reading the type or photographing condition.

According to a second aspect of the present invention, in the X-ray control apparatus according to the first aspect, the imaging mode selecting means includes a designation content mark corresponding to a control condition relating to designation of each sheet key. The mark sheet displayed at each of the operation positions is installed so as to be replaceable, and the control condition storage means is provided with storage content changing means for revising control conditions already stored and adding new control conditions. I have.

According to a third aspect of the present invention, in the X-ray control apparatus according to the first or second aspect, the control condition reading means is provided after the end of imaging of one imaging type in a series of imagings designated by a sheet key. It is configured to automatically read out the photographing condition of the next photographing type from the control condition storing means.

[Operation] Next, the control operation when X-ray photography is performed using the X-ray control apparatus of the present invention will be described. When performing control by the X-ray control apparatus of the present invention, the operator (photographing technician) selects a doctor X-ray imaging request form from a plurality of sheet keys in the sheet key type imaging mode selection means. The user selects and presses a sheet key for simultaneously specifying both the corresponding imaging technique and the type of imaging in a series of imaging using the same imaging technique. Then, the photographing progress status (executing photographing step) in the series of photographing designated by the photographing step detection display means is detected and displayed, and the photographing technique is stored from the control condition storage means in accordance with the designation by the sheet key and the photographing progress status. In addition to the type of expression or the imaging condition being read out as the control condition, the necessary imaging conditions for the imaging type relating to the currently executing imaging step are displayed by the imaging condition display means, and the necessary control proceeds.

When one of a plurality of sheet keys in the photographing mode selection means is pressed, a series of radiographing procedures using the same radiographing technique and a radiographing technique corresponding to the radiographing request form of the doctor's X-ray radiograph request sheet are performed. Since both of the shooting types are specified at the same time, it is not necessary to press the sheet key for designating the shooting type each time the shooting of each shooting type in the series of shootings is completed. Further, since the imaging step detection and display means displays the imaging steps in the designated series of imaging, the operator can always perform X-ray imaging while accurately grasping the imaging progress.

In the X-ray control apparatus according to the second aspect, when a control condition accompanied by a change of a designated content mark displayed at the operation position of each sheet key is to be revised or added, the control condition is provided in the imaging mode selection means. After replacing the mark sheet displaying the designated content mark corresponding to the control condition relating to the designation of each sheet key with a new mark sheet in which the necessary designated content mark has been changed, the control content storage means changes the control condition storage means. Among the stored contents of the means, the photographing condition relating to the sheet key for which the control condition is revised / added is revised or added. Even after the X-ray controller has been installed on the site, the control conditions specified by each sheet key must be
It can be easily changed according to the situation of radiography.

In the X-ray control apparatus according to the third aspect, after the photographing of one photographing type in the series of photographing designated by the sheet key is completed, the control condition reading means can store the control condition without any operation by the operator. The photographing conditions of the next photographing type are automatically read from the means.
