In such a conventional method of setting the decoy image strip f[, it is not necessarily possible to set the optimal photographing conditions. This does not necessarily mean that the patient has undergone imaging at one site in the past; B11) Noto(,

[Objective of the Invention 1] The present invention has been made in view of the above circumstances, and provides an X-ray diagnostic equipment that can always set optimal conditions or imaging conditions close to these and can prevent imaging errors. The purpose is to provide

``Summary of the Invention 1 The outline of the present invention for achieving the objects listed in item 11 is to provide a patient condition input means for setting patient conditions such as the physical condition of a patient to be photographed (9 years of age); Imaging conditions such as tube voltage, conditions for storing X-ray images, image storage means, and a photographer who takes X-ray images based on these conditions and imaging conditions sent from the image storage means. , 'R shadow conditions and a display means for displaying an X-ray image corresponding to these conditions, and an optimum image for the patient to be imaged based on patient conditions set by manual means. or this, I; is characterized in that it is configured to send nearly two projection lines ('l) to the imaging means;

1 Embodiments of the Invention) Embodiments of the present invention will be described in detail below. Inside, body 1 (.

The patient condition input means 1 is configured with a keyboard, etc., which sets and sends patient conditions such as age, region of projection, direction of projection, and chest thickness, and the latest information developed by Akira Sono is provided in advance. Conditions are stored based on the image storage means 2, which stores the X-ray image, the patient conditions at that time, and the tll1 conditions (tube voltage, tube current, etc.), and the condition 1 from the patient condition input means 1. A photographing means 3 for photographing an X-ray image under the photographing conditions sent from the image storage means 2, and a display means 4 for displaying the X-ray image, patient conditions, and photographing conditions stored in the image storage means 2. It is composed of:

As shown in FIG. 2, the condition/image storage unit g22 includes a controller roller 5 and a storage unit such as a magnetic disk device.
6, and an auxiliary storage device 7 such as a floppy disk device.
It is composed of: 1] The controller 5 controls the storage device 6 and the auxiliary storage device 7 based on the patient conditions from the patient condition input means 1. , Ri:
The X-ray images stored in the fa device 6 or the auxiliary storage device 7 are sent to the patient conditions and imaging conditions 4/display 1 stage 4, and the memory corresponding to patient/1 item ('l) of the patient to be imaged is sent. Shoot the completed shooting conditions, - [Send to step 3.

The memory 6a in the hl store K tll 6 includes, for example, 1JJ shown in FIG. . . , image information storage units C1, 02, . . . for storing X-ray images are formed.

Next, the operation of the apparatus having the configuration described in -1- will be explained with reference to the x-ray imaging j' algorithm shown in FIG.

First, the image of the patient to be photographed is input from the patient condition input means 1 to the image storage means 2.

] The rollers 1 to 5 determine whether the imaging conditions for the same patient and the same region are stored in the memory 6a in the storage device 6 based on the input patient conditions, and if so, perform the imaging. The conditions and the corresponding X-ray image are sent to the display means 4 and displayed thereon.

The X-ray technologist judges whether the image quality of the X-ray image is good (B or old) and if it is good, then the GEL at this time is selected. The patient's X-ray image is set to 1 under the imaging conditions.

On the other hand, if the same region has not been photographed in the past, or even if it has been done but the image quality is poor, the controller 5 retrieves the image of the same region and the closest patient condition from the memory 6a in the storage device 6. The imaging conditions of other patients to be covered and the corresponding X-ray images are determined and displayed on the display means 4.

The X-ray technician looks at these imaging conditions and the X-ray image, and if the image quality is good, takes an X-ray image of the patient under the next imaging conditions.

If neither of the above two cases applies, the 1#i condition derived from the patient conditions of the patient to be imaged is sent to the imaging means 3 as the imaging condition at this time to perform X-ray imaging.

In any of the above cases, the adopted II conditions and the X-ray image obtained at this time are stored in the storage unit M as the latest information.
6 in the memory 6a.

In this way, the radiographer always provides the best or most suitable treatment for the patient. X-ray imaging is performed under imaging conditions close to the appropriate conditions (the two sides are close to each other).

Next, we will further revise the effect of H in Section 1 by referring also to the algorithm for determining the dancing image f1 in the case of a chest circle image shown in Figure 5.

Patient article! 1 Patient procedure 1 for chest imaging from manual means 1
When '1' is input to the point []-ra 5, the controller 5 stores the same-removal region from the memory 6a in the storage device 6,
It searches to see if there is any stored data for the same direction of imaging, and then determines from among the stored data the stored data that has the same or almost the same chest thickness value as the patient to whom the R imaging should be performed, and displays this data on the display device. Display on 4.

The X-ray technician retrieves the displayed stored data and, if the image quality is good, adopts the imaging conditions at that time and performs XfilIli.
In addition to performing i-shading, the adopted shooting conditions and the obtained Xlr! The image is stored in the storage device 6.

On the other hand, if the storage device 6 does not store stored data for the same imaging region and the same imaging direction, or if the image quality of the stored data once displayed is not good, the data based on the chest thickness value of the patient Known chest thickness value vs. tube voltage graph (not shown)
The radiography regulations are determined based on the above, and X-ray radiography is performed in accordance with this &1 article f1.

In this case as well, the determined imaging conditions and the obtained X-ray image are i'i[! tm device 6.

In this way, in the case of C1 chest imaging, a bi-optimal or near-optimal imaging strip is obtained! 1 can perform X-ray photography.
