Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is used, for example, in the field of medical diagnosis, and is a radiographic image imaging device that produces radiographic radiation images of a subject. The present invention relates to a radiological diagnostic system equipped with.

(Conventional technology) Currently, commonly used radiological diagnostic systems (
A large number of stimulable phosphor plates (hereinafter referred to as ■P: Imaging Play 1) that are imaged at multiple X-ray image shadow locations are intensively processed in a common image reproduction processing department, and
This department performs reproduction processing of these line images.

Hereinafter, such a conventional line diagnosis system will be explained with reference to FIG. 4.

The radiological diagnosis system shown in the figure is an I
By scanning the TP with an X-ray cassette 41 equipped with an Excite from 300 to 500
It emits visible light with a wavelength of 11 m, and this emitted light can be measured with a photodetector (e.g., photomultiplier tube, diode, etc.) capable of receiving light in a predetermined wavelength range. An X-ray image reading device 2 configured as follows;
After the image is read by the reading device 2, the output signal of the photodetector is non-linearly amplified and converted into digital 1C code, and then this signal is subjected to frequency emphasis and processing (and gradation processing if necessary). , an image processing condition 3 for storing this result in a storage means such as an image memory, and sequentially reading out the X-ray image data stored in this image memory etc. and converting it into an analog signal. An X-ray image processing device 4 converts the X-ray image data into an optical signal by amplifying the data and then inputting it to a storage light source, and records the optical signal on a photographic film or the like via a lens system. X-ray image recording device 5 that separately irradiates and forms 7 x 85! images
The X-ray image of the subject formed on the recording material using these devices is necessarily observed for medical diagnosis.

In addition, in the system d3 described above, the image processing device 3
The subject information required for image processing in the 1[0 hard ij IP thick thinner A radiographic image control device (hereinafter simply referred to as a control terminal) 6 is used for registering the images with the processing device 3.

The external configuration of this control terminal 6 is shown in FIG. 5, and its internal configuration is shown in FIG.

The illustrated control terminal J-6 is a power switch 6c.

A keyboard 6b for inputting subject-related information, etc., and a cart reader (5a) for reading the stored contents of the ID cart.

A display section 6e with a touch panel function and a parcode reader 6d for reading hard information are provided at appropriate locations. This kind of control terminal 6 is
(See Figure 1 of Publication No. 72040). The operator operates these as appropriate (panifres the subject-related information, etc.).Next, the configuration of this control terminal 6 is as shown in FIG.
1) Identification that reads and digitizes the output signal from Zenza 7 that detects a unique identification code (for example, one of a series of consecutive numbers) displayed on the label 16 affixed to a predetermined location. A code reading unit 21, a control unit 22 including a CPt1, etc., which is the control center of the water control terminal G,
A transmission control unit 23 and a transmitter 24 that transmit the read identification code and the subject-related information entered from the keyboard 6b to the image processing device 3, a backup storage device 19 for recovery in case of line failure, etc. The display section 6e is for displaying the operating status and operating procedures of the three processing devices.
, and a cart reader 6a. .

The important functions that the control unit 22 in J3 of such a control terminal should perform are: during the above-mentioned control (in addition to the function as a ward, the IP unique identification code used for each eye image and the keyboard 6b or card reader This is achieved by associating the information from 6a with the subject-related information.For this purpose, a register or memory (not shown) is provided to temporarily store these identification codes and input data.

The operation of the control terminal 6, whose functions have been described in this way, will be explained later on for each photographing stand 8. The control unit 22 is configured to respond to a trigger signal ST from the X-ray pupil shadow light source (1' shown in the figure) of 4. Such a control terminal 6 is normally shown in FIG. It is installed and used as appropriate.

In other words, the removal area consists of a shooting location that can accommodate one imaging platform 8 for a cassette 12 containing a single IP, and an imaging location that is equipped with a imaging platform 14 equipped with a magazine 15 that accommodates a plurality of IPs. They are placed inside the shadow location groups 10B to 1ON.

Then, the terminal 6 allows input of subject-related information by selecting any of the imaging part keys 61 on the keyboard 6b as shown in FIG. IP reading mode (recording mode), image processing conditions (e.g. gradation processing, spatial frequency processing, etc.), imaging method, image horizontal inversion instruction, X-ray imaging conditions (e.g. KV, MA, S"C, MAS") etc.) were set automatically.

In addition, the setting of the data to the Brisera described above is carried out in accordance with the selection operation of the image region key (head, neck, chest, abdomen, pelvis, upper limbs, lower limbs) 6q. At this time, the selection of image processing conditions and X-ray projection conditions is performed by operating individual radiographing region keys set correspondingly to each.However, here, for reasons of space efficiency and operational efficiency, the above Two types of imaging region keys relating to both conditions are provided, and both of the two can be selected by selecting only one system of imaging region V- in the X-ray tail shadow condition classification.

That is, the control unit 2 provides basic data that can logically determine the image processing conditions related to the selected setting data.
By storing it in the BACK-RAM (not shown) of No. 2, the image processing conditions are automatically set.

By the way, the selection items selected by each of the ten keys on the keyboard Gb (or the cart reader) are all displayed on the display section 6a.
will be displayed. In this case, the data related to the X-ray imaging conditions are displayed.
It is configured to be sent as a setting signal to the X-ray high voltage device from the control section 22 that controls the control terminal 6 body to the X-ray control device 26.

In the conventional radiological diagnostic system described in detail above, the image processing conditions and X-ray imaging conditions suitable for P-type imaging can be comprehensively controlled by the control unit, so the signals from the control unit can A device that automatically controls the amount of light emitted from an X-ray tube to a value that provides optimum image quality (Problem to be solved by the invention) However, such conventional radiological diagnostic systems Then, when setting the shadow line A4↑ of the X-ray imitation, it was only a matter of setting the X-ray exposure conditions (kv, mA, Sec or kV, mAS, etc.).

Therefore, during actual shooting, -C is the remaining shooting strip ii,
For example, it is difficult to select each part of the X-ray equipment, such as the imaging technique (butsky imaging, tomography, mammogram, etc.), copy table, X-ray tube, etc. It had to be carried out using a line tracking device. In other words, although we have taken great pains to provide optimal images by automatically controlling everything from photography to image processing, we have not been able to fully configure the remaining photography conditions mentioned above, which have the greatest effect on image quality, without requiring operator intervention. I had entrusted it to him.

In other words, for the remaining imaging conditions, which are uniquely determined by the area to be imaged and the purpose of imaging, operators such as X-ray technicians memorized the imaging conditions and set them accordingly, so there was a risk of human error. However, I often forgot the above-mentioned conditions for taking photos that were only available in text boxes.

Furthermore, the above setting operations increase the time from imaging to image processing, increasing patient processing capacity (throughput 1~).
This has led to a low 1z, putting a burden on patients and having an adverse economic impact. Therefore, there is a strong demand for solutions to these problems.

Therefore, the present invention provides a radiological diagnostic system that can prevent human errors and reduce diagnostic efficiency by presetting the status of each part of the X-ray imaging device corresponding to specific object-related information. To cover the purpose.

"Structure of the Invention" (Means for Solving and Overcoming the Problems) The structure of the present invention for achieving the above-mentioned object is to perform radiographic imaging specified by input object-related information in the radiological diagnosis system described above. Record the status information of each part of the device.
and a control means for setting and controlling each part of the Q4 radiation imaging apparatus so that the subject can be photographed immediately based on the stored status information.

(Function) The function of the present invention having the above configuration is based on image processing conditions suitable for IP [H shadows specified by input of subject-related information and X-ray "υ shadow conditions (+<v, IIIA, sec. or k
v.

Based on the imaging system conditions (imaging technique, decoy stage, X-ray tube, etc.), each part of the radiographic imaging device is automatically set and controlled to immediately control the decoy imaging status of the subject.
I'm Lno just like I am.

(Example) The radiological diagnostic system I of the present invention will be explained below with reference to the drawings.

There is.

The status information of each part of this radiographic imaging device is inputted as subject-related information, such as an X-ray tube, a Butsky device, a snapshot device, etc., which are installed in the X-ray imaging device, which are specified by inputting the region to be imaged. This is selection information.

First, before performing X-ray imaging of the subject, we examined the status of each part of the system and adapted it to the subject.
' Perform the following operations to cover the object.

For example, the subbellator is shown in Fig. 3 as subject-related information.
Press any of the shadow area keys 6f on the rear board 6. If the original shape of the subject's head is to be made here, the key 6f' on which "1 AD-1" is written is pressed. In other words, detailed items regarding the subject's head are displayed on the display section 6e together with a selection key (not shown).

A Bereta [Press the corresponding selection key on the detailed item next to it.

By this pressing operation, the CPU 22a selects the image processing information, X-ray photography information, shadow technique, R engraving,
The status information (hereinafter also referred to as X-ray imaging system conditions) of each part of the radiographic imaging apparatus, including the status information of the X-ray tube, etc., is read out.

In addition, data related to X-ray imaging conditions and X-ray imaging system conditions are displayed on the display section 6e, and are also displayed on the X-ray control device 26. High voltage 1 Herance 27° X-ray tube 9a, gb
The setting signal to the X-ray imaging device 1 consisting of the following components is transmitted from the control unit 22 to the X-ray control device 2G. Note that the X-ray exposure from the X-ray high voltage device 26 is as follows:
This is done by pressing the X-ray exposure switch 25 attached to the control terminal 6.

In the X-ray control device 26, as shown in the first diagram, the control section 2
27') Receive the X-ray imaging conditions and X-ray imaging system condition setting data, etc. at the I/F 26e, transfer it to the internal CPU bus, and then record it in the RAM 261. It looks like it's straining.

For example, if state information such as Butsky imaging, metal removal engraving, and X-ray tubes 9a and 9b is stored in advance as the X-ray removal system condition data, the Butsky apparatus is controlled by the control signal from the X-ray control device 26. 29, the metal engraving 14 (in this case, the snapshot device 30 is automatically turned off) and the X-ray tube 9a are selected. In the case of buttsky photography, a sequence program is prepared for the buttsky device to detect a signal indicating whether the cassette (including IP) is being sent to camera 1, and a signal to detect whether this is satisfied. . If this is not satisfied, X-ray control device 2
6: Do not expose to X-rays J: Works like a sea urchin. Therefore, even if the operator tries to operate the snapshot device 30 by mistake, the
The interlock from the line control device 26 has long been disabled. When selecting the X-ray tube 9a, the selection signal from the X-ray control device 26 activates the relay of the high voltage switch 28 (in the figure, when selecting the X-ray tube 9a, the high voltage 1 to connect the lance and the X-ray tube 9a.Such an operation is performed by the X-ray tube 9b, the photographic device 30
The same applies when overriding the setting control.

Here, the X-ray imaging conditions are roughly classified into the following: radiographic technique, imaging table, and X-ray tube, but this X-ray imaging condition data also applies. As described above, Brisera 1 is set so that it can be automatically set together with the above-mentioned copy shaping part key selection.

For example, when an X-ray tube 98 is set as an imaging technique such as Zoky imaging, carving, and an X-ray whistle hanging from the Otsuki, along with a certain distance image part key selection, one side that emits X-rays,
The X-ray data transmitted through the patient and the receiver (so-called R on the receiving side)
Shape light will be specified. In this state, when the operator sets the cassette i in the Boogie device for transporting metal engraving, distance imaging becomes possible immediately with the press of a button.

Conventionally, if the original form system condition data were not automatically set, it was necessary to go to the X-ray control device of the X-ray high voltage equipment that controls these data and set them anew. There wasn't.

As described above, according to the system of this embodiment, the IP reading mode (recording mode), image processing conditions (for example, C, gradation processing, spatial frequency processing), original method, image externality, etc. Reversal instructions/X-ray photography conditions (e.g. 1ku\/,
M△, SEC, MAS, etc.)・X-ray travel imaging system conditions (e.g. mud shadowing, metal engraving, etc.)

X-ray tubes, etc.) can be set automatically.

In addition, image processing conditions, X-ray original shape conditions, and X-ray contrast system conditions (
For example, all settings other than Okakage Technique, Dance Carving, X-ray Tube, etc. can be changed using each key (J, of course. Also, the settings of the preset data mentioned above can be changed using the original part key (Head, neck, chest, abdomen, pelvis, upper limbs, lower limbs). At this time, image processing conditions, X-ray photography conditions, and selection of In principle, this is done by operating individual original part keys provided corresponding to each original part, but for reasons of space efficiency, operational efficiency, and accuracy, three types of original parts related to all of the above conditions are used. etc., it may be drawn so that both can be selected by one system of original part keys selected in the X-ray original condition classification.

When configured in this way, the selected settings
The backup RA, which is a storage means of the control unit 22, stores basic data that can uniquely determine the image processing conditions '1 related to image processing.
It is sufficient to store it in M 22 e and d3.

In addition, it is also possible to configure the system so that X-ray imaging conditions can be automatically set from the selection operation of one system of original part keys that can be selected by image processing condition classification. For example, in the case of the above-mentioned head, details such as the head outline, paranasal sinuses, lower jaw, eye sockets, etc. can be specified by pressing the selection key.

Therefore, it is possible to further improve the accuracy of the image quality of both CR and CR images of the Bricera 1 data related to image processing conditions and X-ray imaging conditions.

In the radiological diagnosis system configured in this manner, the terminal control unit 6 can comprehensively control image processing conditions, X-ray imaging conditions, X-ray removal system conditions, etc. suitable for IP imaging, so that original processing can be performed. Furthermore, each part of the X-ray imaging device is automatically set to be optimal for the distance imaging purpose of the key to be scanned, which prevents mistakes in selection due to human error or forgetfulness. I can do it.

Although one embodiment has been described above, the present invention is not limited thereto, and can be modified in various ways without departing from the gist thereof. For example, in the above embodiment,
Although two wire tubes are shown, three or more wire tubes may be used. Even if configured in this way, would it be possible to obtain the same effect as described above?

-21= [Effects of the Invention] As described in detail above, according to the present invention, the state of each part of the X-ray contrast device can be set in advance, thereby reducing human error and improving diagnostic efficiency. The system can be provided.
