Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image diagnostic apparatus for performing a radiographing operation on a plurality of patients.

[0002]

2. Description of the Related Art A mass examination of a chest using an X-ray diagnostic apparatus has been performed for a long time. With the recent widespread use of advanced image diagnostic equipment such as X-ray CT equipment and magnetic resonance easing equipment (MRI equipment), for example, lung cancer examination using X-ray CT equipment and cerebrovascular examination using MRI equipment. Is being targeted for mass screening.

On the other hand, as one of the mass examinations for lifestyle-related diseases, for example, a mass examination of the upper digestive tract, that is, the stomach is performed. In addition to being carried out at hospital facilities, this mass examination of the stomach may be performed by dispatching medical staff along with vehicles such as buses equipped with X-ray diagnostic equipment to public halls and schools where examinees are likely to gather. Many. In any case, because the examination site is the stomach, it will force the examinee to stop eating for about half a day before the examination, so it is usually carried out from about 8:00 to 12:00 in the morning. Often. It is not uncommon for the number of examinees during that period to reach 70 to 80. Therefore, the medical staff involved in this group medical examination becomes extremely busy within a limited time.

By the way, in the group medical examination of the stomach, the photographing direction and the number of photographs for each examinee are standardized to some extent. For example, with the bed of the X-ray diagnostic apparatus horizontal, with the patient lying on the bed top (in the lying position),
Rotating the X-ray tube and X-ray detector around the examinee,
By changing the orientation of the examinee's body, six X-ray images in different directions are taken, and finally one image is taken with the bed upright, for a total of seven X-ray images. is there. This is called the 7-sheet method. However, not all images are taken according to the standard, and the number of images to be taken can be increased as necessary, depending on the judgment of the operator who is performing X-ray photography.
On the contrary, it is also practiced to omit photographing in a certain direction.

[0007] In X-ray photography, it is necessary to associate the photographed X-ray image with the examinee. Therefore, the examinee information such as the reference number or the name of each examinee (hereinafter referred to as the examinee ID). .) Will be registered in the X-ray diagnostic apparatus. As the method, for example, the examinee ID input through the input unit of the X-ray diagnostic apparatus may be imprinted on the image, or the image data and the examinee ID data may be stored in the X-ray diagnostic apparatus. I am trying to be able to correspond. However, in any case, when the imaging of one examinee is completed, an operation to input that the imaging of the examinee has been completed by the medical staff such as the surgeon before taking the image of the next examinee. Alternatively, an operation for inputting the examinee ID of the next examinee is required.

However, as described above, the number of images to be taken is not always constant for each examinee, and the medical staff at the time of a group examination is extremely busy, so sometimes it is necessary to input that the examination of the examinee has been completed. There is an inconvenience of forgetting the operation to perform or the operation of inputting the examinee ID of the next examinee, and taking the image of the next examinee while the examinee ID of the examinee is held. It was

[0007]

Thus, if the next examinee is photographed while the examinee ID of the previous examinee is held, the actual examinee and the X-ray diagnostic apparatus side This causes a mistaken file that does not match the person who is recognizing the patient, which greatly impairs the diagnosis by the image interpretation doctor after image capturing. Therefore, the correction must be performed before the image interpretation, resulting in useless backtracking work, which impairs the efficiency of the medical examination.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an image diagnostic apparatus capable of preventing a mistaken file in which a photographed image does not match an actual examinee. To do.

The present invention is applied to an X-ray diagnostic apparatus, an X-ray CT apparatus, an MRI apparatus, etc. as an image diagnostic apparatus. Embodiments will be described.

[First Embodiment] First, an image diagnostic apparatus according to claim 1 of the present invention will be described as a first embodiment.

FIG. 1 is a system diagram showing a schematic configuration of an X-ray diagnostic apparatus as an image diagnostic apparatus according to claim 1 of the present invention. As shown in the figure, the main components of this X-ray diagnostic apparatus are, for example, an imaging apparatus 1 for taking an image of the examination site of the examinee using X-rays, and a bed 2 on which the examinee P is placed.
It can be roughly divided into a control device 3 for controlling the operation of the X-ray diagnostic apparatus and processing data. Although FIG. 1 shows the imaging device 1 and the bed 2 separately from each other, they may be structurally connected to each other although they are functionally different.

The imaging apparatus 1 includes a support arm 1 in which an X-ray tube 11 and a two-dimensional X-ray detector 12 are curved, for example, in a substantially C shape.
It has so as to face both ends of 3. The support arm 13 is supported by a support portion (not shown),
In order to set the photographing direction to an appropriate direction, it can be moved within a predetermined range along the curving direction and can be rotated around a support shaft. Further, the bed 2 is tiltable at least between a vertical position and a horizontal position, and supports the top plate 21 on which the examinee P is placed. The top plate 21 can be moved in a plane while being supported by the bed 2, and one end of the top plate 21 is provided with a step 22 for supporting the examinee in a standing position.

The two-dimensional X-ray detector 12 outputs an X-ray image intensifier 12a which outputs a transmission image of the examinee obtained by weak X-ray irradiation as a bright optical image.
And a television camera 12b that captures an image of the output phosphor screen of the X-ray image intensifier 12a. However, the present invention is not limited to this, and the two-dimensional X-ray detector 12 is composed of, for example, a plurality of X-ray image detectors arranged in a matrix, which is composed of a laminated body in which a fluorescent plate and a semiconductor photosensor are optically coupled. You may.

The control device 3 has a central function for controlling the entire X-ray diagnostic apparatus, and includes a processor 31 having a CPU as a main element and a memory 32 necessary for processing.
Etc. are provided and are organically connected to each of the following components including the imaging device 1 and the bed 2 via a bus line 33. That is, the control device 3 inputs various instructions and numerical information for controlling the X-ray exposure conditions, the imaging direction, the up and down movement of the bed 2, the position of the tabletop 21, and the like. An input unit 3a having a mouse, a trackball, a keyboard, etc. for inputting the examinee ID and the alternation of the examinee, and a examinee ID registration unit 3 for registering the examinee ID.
4. Image recording unit 3 for recording the collected diagnostic images of the examinee
5 is provided and connected to the bus line 33.

Further, the control device 3 includes a first detector 3 for detecting that a predetermined image is taken by the image taking device 1.
6, when a detection signal is obtained from both the first detector 36 and the second detector 37, which detects that the final process of the photographing by the photographing device 1 is completed. , The indicator 38 which issues a signal for prompting the input of a new examinee ID, and the signal issued from the indicator 38,
The photographing operation of the photographing device 1 is prohibited and the indicator 38
An interlock circuit 39 is provided for canceling the prohibition of the photographing operation when the examinee ID or the alternation of the examinee is inputted from the input unit 3a after the instruction signal is issued from the bus line 33. It is connected to the.

The first detector 36 is, for example, the input unit 3
It is possible to detect that an instruction signal for issuing an X-ray exposure instruction is issued from the control device 3 to the imaging device 1 after the examinee ID and the alternation of the examinee are input by a.

Further, in an X-ray diagnostic apparatus of a type in which the bed 2 is tilted (note that this type is rare in the bed of an X-ray CT apparatus or an MRI apparatus), the bed 2 is placed substantially vertically when the examinee is placed. Since the bed 2 is always set to the substantially vertical position even when the patient is lowered to the position, the second detector 37 causes the bed 2 to be in the substantially vertical position after the X-rays are exposed in the imaging apparatus 1. It is only necessary to be able to detect that Alternatively, for example, when performing a mass examination of the stomach by the X-ray diagnostic apparatus using, for example, the 7-sheet method, the 7th image is taken in the standing state, so that it is detected that the image was taken in the standing state. You can do it. And sleeper 2
X-ray diagnostic device that moves vertically (in addition, X-ray CT
The bed of the apparatus and the MRI apparatus is almost this type), and the bed 2 is placed at the lowest position when the examinee gets on and off, and in this case, the second detector 37 is used in the imaging apparatus 1. It suffices to be able to detect that the bed 2 is at the lowest position after the X-rays have been exposed.

Further, an interlock circuit 39 for prohibiting or releasing the photographing operation in the photographing apparatus 1 is provided.
Shuts off the supply of high voltage to the X-ray tube 11,
A circuit that releases the interruption may be used.

The X-ray diagnostic apparatus is provided with a display device 4 for displaying an image at the time of radiographing, and an operator is suitable for radiographing while looking at the image displayed on the display device 4. Positioning will be performed. In addition, the display device 4 also displays the number of images to be taken, the shooting setting conditions, the examinee ID, and the like, if necessary.

Next, a standard procedure for mass examination of the stomach, which is the upper gastrointestinal tract, using the X-ray diagnostic apparatus configured as described above is shown together with the bed angle at that time. This will be described with reference to the flowchart of No. 2.

First, in step 1, the operator confirms the examinee and sets the examinee ID using the input unit 3a. At this time, the bed 2 is in a substantially vertical position (the bed angle is about 90 degrees).
It is in. Then, as step 2, the examinee is placed on the bed 2. At this time, the bed 2 is in a substantially vertical position (the bed angle is about 90 °).
Therefore, the examinee P rides on the step 22 of the top 21. Next, the procedure proceeds to step 3, in which the examinee is administered a contrast agent (for example, barium), and the bed 2 is tilted to a substantially horizontal position (bed angle about 0 degrees). By rotating the support arm 13 having the X-ray detector 12, the diagnostic region to be imaged is positioned, and then the imaging operation, that is, the X-ray is exposed and the first image is taken.

Hereinafter, as steps 4 to 8,
With the bed 2 in a substantially horizontal position (bed angle about 0 degrees),
By changing the direction of the examinee or changing the direction of the support arm 13, the second to sixth images are sequentially captured. Finally, in step 9, the bed 2 is returned to the substantially vertical position (bed angle about 90 degrees), and the seventh image is taken. This completes the standard radiographing with the 7-image method, and the X-ray images captured respectively are stored in the image recording unit 35 in association with the examinee ID, and in step 10, the examinee is taken from the bed 2. I will take it down.

Therefore, the operations from step 1 to step 10 are repeated for the next examinee.

The above steps show the standard procedure at the time of mass examination, but not only the standard procedure, but, for example, between step 3 and step 8, what the operator does extra If it is determined that a certain number of images should be taken, it is determined that additional images may be taken, or that between the steps 3 and 8, the operator may omit shooting from a certain direction. In this case, the total number of shots is reduced in this case. Generally, in such a case, a mistake is likely to occur in setting the examinee ID.

Therefore, according to the present invention, even if the operator decides that some extra images need to be taken between step 3 and step 8 and takes those images, the image is taken as step 9 at the end. Even if only a small number of images are taken because it is determined that the shooting from a certain direction may be omitted between step 3 and step 8, finally, as step 9, Almost vertical position (bed angle about 90
We try to prevent mistakes by paying attention to the fact that the shooting is performed again.

That is, the first detector 36 detects that the examinee ID is input in step 1 and that an image is taken in any of steps 3 to 8. In addition, in the second detector 37, step 3
From step 1 to step 8, it is detected in step 9 that the bed 2 is in a substantially vertical position, or in step 9, the bed 2 is detected.
It is detected that the image was taken in a state where is in a substantially vertical position. The detection by the first detector 36 and the second detector 37 that imaging has been performed is not limited to step 9, but the X-ray to the imaging device 2 may be detected between step 3 and step 8. It suffices if it is possible to detect that the exposure instruction has been issued.

Therefore, if the detection signals are respectively obtained from the first detector 36 and the second detector 37, it can be judged that the predetermined photographing of one examinee has been completed. Therefore, the output signals of the first detector 36 and the second detector 37 are matched (AND), and an instruction signal is issued from the indicator 38, so that the photographing operation of the photographing apparatus 1 is prohibited by this signal. Then, the interlock circuit 39 is operated. At the same time, the signal from the indicator 38 is also used as a signal for prompting the operator to input a new examinee ID.
As the method, various well-known means such as providing a warning light on the input section 3a, blinking the warning light, making an electronic sound, displaying a message on the display device 4, etc. can be appropriately adopted. Then, when the operator performs an input operation of a new examinee ID using the input unit 3a, the signal from the indicator 38 is reset, the operation of the interlock circuit 39 is released, and the imaging operation by the imaging device 1 is performed. It is returned to a possible state.

The flow of such control is shown in the flow chart of FIG. Hereinafter, description will be given based on the flowchart shown in FIG.

That is, in step 21, it is determined whether or not the examinee ID is input. If the examinee ID has been input (YES), then in step 22, it is determined whether or not photographing has been performed. If the image is taken here (YES), a predetermined output signal is generated in the first detector 36 in step 23. Further, in step 24, it is determined whether or not the image was taken at the vertical position of the bed 2. If the image is taken at the vertical position of the bed 2 (YES), a predetermined output signal is generated in the second detector 37. Therefore, the AND of the first detector 36 and the second detector 37 is taken. At this time, as a step 25, a signal is issued from the indicator 38 and the interlock circuit 39 is operated, The photographing operation of the photographing device 1 is prohibited.

Then, in step 26, it is determined whether or not to end the series of photographing, that is, whether or not an instruction to end the group medical examination is given. Normally, the surgeon performs the ending operation only when the operation is ended, so when the operation is executed (YES), the series of operations ends.
If nothing is operated (NO), the process proceeds to the next step 27. In this step 27, the operator prompts the operator to input a new examinee ID by the signal from the indicator 38. Therefore, in step 28, it is judged whether or not a new examinee ID is input, and if it is input (Y
ES) Proceeds to step 29, the interlock operation by the interlock circuit 39 is released, and the imaging operation for the next examinee is enabled. If not input (NO), the procedure returns to step 25 and the interlock operation and the examinee ID. The operation of input instruction of is continued.

As described above, according to the present invention, when the examination (X-ray photography) of one examinee is completed, the examinee I of the next examinee is examined.
Unless D is input, the examination of the next examinee cannot be started. Therefore, unlike the conventional case, by continuing the examination of other examinees without changing the setting of the examinee ID, it is possible to eliminate a mistake file that causes a discrepancy in the correspondence between the photographed image and the examinee. In particular, it is possible to prevent work mistakes during group examinations, especially when medical staff are very busy. Therefore, it is possible to improve the work efficiency of the medical staff without causing a backtracking work at the time of image interpretation.

The present invention is not limited to the above-described embodiment, but can be implemented in various forms. For example, the present invention is not limited to the X-ray diagnostic apparatus, and can be applied to a mass examination performed using an image diagnostic apparatus such as an X-ray CT apparatus or a magnetic resonance imaging apparatus (MRI apparatus).
Needless to say, the present invention is not limited to the image diagnostic apparatus for mass examination, but can be applied to an image diagnostic apparatus for normal diagnosis.

[Second Embodiment] Next, an embodiment of an image diagnostic apparatus according to claim 2 of the present invention will be described as a second embodiment. In the image diagnostic apparatus according to the present embodiment, the control unit of the image diagnostic apparatus according to the first embodiment described above is connected to an examination reservation system that manages patient information of the examinee and examination appointment time, and the like.

An allowable load range is set for the load sensor 23 and the strain sensor 24, and if the allowable load range is within this allowable load range, the sheets and accessories (drip board, mat, etc.) necessary for the inspection are not to be examined. Separately, it can be placed on the bed 2.

The control device 3 has a central function for controlling the entire X-ray diagnostic apparatus, and includes a processor 31 having a CPU as a main element and a memory 32 necessary for processing.
Etc. are provided and are organically connected to each of the following components including the imaging device 1 and the bed 2 via a bus line 33.

An indicator for issuing a signal for prompting selection of a new examinee ID when detection signals are obtained from both the second detector 37 and the first detector 36 and the second detector 37. 38 and the first detector 36, when a predetermined time (required inspection time described later) has elapsed from the time when the photographing by the photographing device 1 is detected, a signal to that effect is given. A timer circuit 40 for sending to the processing processor 31 is provided, and each is connected to the bus line 33.

Further, the control device 3 is connected to an examination reservation system S for managing patient information of the examinee, examination appointment time, etc., and the processing processor 31 sends the patient information and examination appointment of the examinee from the examination appointment system S. Call the time etc.,
A list of examinees is automatically displayed on the display device 4 in the order of the examination reservation time. Further, the processing processor 31 calculates the required inspection time for each examinee from the examination reservation time of the examinee, and starts the timing by the timer circuit 40 from the time when the first detector 36 detects the start of imaging. Then, when the required inspection time has elapsed, a warning is displayed on the display device 4 in accordance with a signal to that effect sent from the timer circuit 40. The contents described above will be described later in detail.

In the first detector 36, after the examinee ID is selected by the input unit 3a, for example, an instruction signal for issuing an X-ray exposure instruction is issued from the control device 3 to the imaging device 1. Anything that detects the fact may be used.

Further, the second detector 37 may be any one that detects that the load by the examinee P has been removed from the bed 2 after the X-rays have been emitted from the imaging apparatus 1.
Specifically, the load sensor 23 or the strain sensor 24 described above may be used.

The display device 4 is a means for displaying an image at the time of photographing, and the operator performs positioning suitable for photographing while looking at the image displayed on the display device 4.
In addition, the display device 4 displays a list of patients to be described in detail later, patient information, and a warning that "the required examination time of the examinee has elapsed (the examination reservation time of the next examinee has already passed. "Warning)" is displayed.

Next, using the X-ray diagnostic apparatus configured as described above, a procedure in which an intravascular examination, which is an example of so-called X-ray fluoroscopy, is repeatedly performed on different patients will be described.
The state of the load applied to the bed at that time is shown in FIG.
This will be described with reference to the flowchart shown in FIG.

First, in step 11, the operator confirms the name of the examinee who is to be examined next from the examinee list displayed on the display device 4, and inputs the examinee ID to the input section 3a.

At this time, the bed 2 is loaded by the examinee. Next, in step 13, the operator starts an intravascular examination. Specifically, the surgeon rotationally drives the support arm 13 having the X-ray tube 11 and the two-dimensional X-ray detector 12 to position it near a diagnostic site to be seen through, and then to perform fluoroscopic examination. The operation, that is, continuous exposure of X-rays is started to start the intravascular examination. At this time, the first detector 36 detects the start of X-ray exposure, and a signal to that effect is sent to the indicator 38. In addition, the intravascular examination can be performed while changing the direction of the support arm 13 while confirming the situation inside the blood vessel from various directions. And step 14
As a result, the operator stops the X-ray exposure at the end of the intravascular examination. At this time, the X-ray fluoroscopic image recorded during the examination is stored in the image recording unit 35 in association with the examinee ID. Then, in step 15, the operator removes the examination tube from the examinee and then removes the examinee from the bed 2. At this time, the bed 2 is in a state in which the load of the examinee is removed, that is, the load is zero, the second detector 37 detects this, and a signal to that effect is sent to the indicator 38. The indicator 38 which received this is the first
ANDing the detector 36 and the second detector 37 of
It issues a signal to the processor 31. Then, the processor 31 performs, for example, "a warning display to the effect that the examinee ID of the next examinee is selected" in the examinee list displayed on the display unit 4. Specifically, as shown in FIG. 9, for example, by overlapping the examinee list 4a with "the examinee I of the next examinee I.
A warning "4a-3" indicating that D is selected is displayed. In addition to the method of displaying the warning in this way, for example, the input unit 3
A warning light may be provided in a, the light may be turned on or off, an electronic sound may be emitted, and various known means may be appropriately adopted.

Then, the operations from step 11 to step 15 are repeated for the next next examinee.

The above steps show the basic procedure for the intravascular examination. However, step 1
In 1, when the operator forgets to perform the operation of selecting the examinee ID of the next examinee, the examination of the next examinee will be carried out with the previous examinee ID. A mistake occurs in setting the examinee ID, and a mistake file is generated. Therefore, the present invention utilizes the examination appointment time called from the examination appointment system S even when the operator forgets to perform the operation of selecting the examinee ID of the next examinee in step 11, Even if it is the examination appointment time of the examinee (strictly speaking, the scheduled start time of examination), if the examination of the previous examinee continues, the warning display to that effect will be displayed, and I noticed that the person forgets to perform the operation of selecting the examinee ID.

That is, in step 11, the examinee ID
When is selected, the processor 31 calculates the difference between the examination appointment time of this examinee and the examination appointment time of the next examinee, that is, the required examination time. Then, in step 13, when the first detector 36 detects the start of X-ray exposure, the processor 31 causes the processor circuit 31 to detect the start of the X-ray exposure.
Start timing with 0. Further, when the timer circuit 40 detects that the required inspection time has elapsed, the processor 31 indicates to the display device 4 that "the required inspection time has elapsed (the next scheduled examination start time of the examinee has arrived. The warning display of "Yes" is displayed. This warning display is, for example, as shown in FIG. 10, overlaid on the patient information 4b, and is a "warning indicating that the required examination time has elapsed (the examination start scheduled time of the next examinee has arrived)" 4b-5. May be displayed. In addition to the warning display, for example, a warning light may be provided in the input unit 3a to blink the light, emit an electronic sound, and various known means may be appropriately adopted. Then, when the operator selects a new examinee ID on the input unit 3a, the display of the "warning that the predetermined inspection time has elapsed" 4b-5 is canceled on the display device 4, and the timer circuit 40 is released. At, the clock is reset and the next new clock is started.

A flow chart of such a control flow is shown in FIG. Hereinafter, description will be given based on the flowchart shown in FIG.

That is, in step 21, it is determined whether the examinee ID has been selected. If the examinee ID is selected (YES), then in step 22, the difference between the examination appointment time of this examinee and the examination appointment time of the next examinee, that is, the required examination time is calculated. And step 23
, It is determined whether X-ray exposure has started, and X
When the radiation of the line is started (YES), as a step 24, the first detector 36 detects this and generates a predetermined output signal to the indicator 38. At the same time, the timer circuit 40 starts counting time. Further, as step 25, it is judged whether or not a predetermined inspection time has elapsed. If the predetermined inspection time has elapsed here (YES),
A signal to that effect is sent from the timer circuit 40 to the processor 31, and the processor 31 having received this signal displays a warning to that effect on the display device 4 as step 26. Then, the warning display is continued until the operator performs an ID selection operation for a new examinee, and at step 28, when the operation is performed (YES), at step 29, the warning display is canceled. , Move to the next examination of the examinee.

The control flow described above will be described below along with the flow of actual patient replacement. FIG. 12 shows a time chart for explaining the flow. However, in the figure, in order to simplify the description, it is assumed that the timer circuit 40 starts the timing from the time when the examinee ID is selected.

First, when the operator confirms the name of the patient A who is the first examinee from the examinee list displayed on the display device 4 and selects the examinee ID, the operator displays the name on the display device 4. Displays the patient information regarding this patient A. Also,
At the same time, the processor 31 immediately causes the examination appointment time (AM 10:00) of the patient A who is the examinee and the examination appointment time (AM 10: 3) of the patient B who is the next examinee.
0), that is, the required inspection time (30 minutes) is calculated, and the timer circuit 40 starts counting time. When the operator starts the intravascular examination and starts the X-ray exposure, the first
This is detected by the detector 36, and a signal to that effect is sent to the indicator 38. Here, the required inspection time is 3
When the intravascular examination is finished before 0 minutes and the X-ray exposure is stopped, the X-ray fluoroscopic image recorded during the examination is associated with the examinee ID in the image recording unit 35. Saved. Further, when the patient A gets off the bed 2, this is detected by the second detector 37, and a signal to that effect is sent to the indicator 38. The indicator 38 that has received this ANDs the first detector 36 and the second detector 37 and outputs a signal to the processor 31. The processor 31 having received this, for example, in the examinee list displayed on the display unit 4, "warns that the examinee ID of the patient B who is the next examinee is selected" 4a-3 (see FIG. 9). Is displayed.

Further, when the surgeon selects the examinee ID of the patient B who is the next examinee, the display unit 4 indicates that "the examinee ID of the next examinee is selected." The display of the warning "4a-3" is canceled and the patient information regarding the patient B is displayed instead. Further, the timer circuit 40 resets the time measurement. Further, in the processor 31, the difference between the examination start time (AM10: 25) of the patient B who is the examinee immediately and the examination start time (AM10: 55) of the patient C who is the next examinee, that is, the required examination. The time (30 minutes) is calculated, and a new time measurement by the timer circuit 40 is started. The operator starts the intravascular examination, and X
When the radiation of the line is started, this is detected by the first detector 36, and a signal to that effect is sent to the indicator 38.
Here, when the intravascular examination is finished before the required examination time of 30 minutes has elapsed and the X-ray exposure is stopped, the X-ray fluoroscopic image recorded during the examination corresponds to the examinee ID. It is attached and saved in the image recording unit 35. Further, when the patient B gets off the bed 2, this is detected by the second detector 37, and a signal to that effect is sent to the indicator 38. Receiving this, the indicator 38 changes the first detector 36 and the second detector 3 from each other.
AND with 7 and issue a signal to the processor 31. In response to this, the processor 31 receives, for example, a “warning to select the examinee ID of the patient C who is the next examinee” in the examinee list displayed on the display unit 4a-
3 is displayed.

However, for example, at this time, before the operator selects the examinee ID of the patient C who is the next examinee,
It is assumed that the required inspection time of 30 minutes has elapsed. In such a case, the timer circuit 40 to the processor 31
A signal to that effect is sent to the display processor 4, and the processor 31 having received the signal newly displays a "warning indicating that the predetermined inspection time has elapsed" 4b-5 (see FIG. 10).

Further, when the operator selects the examinee ID of the patient C who is the next examinee, the "warning that the predetermined examination time has elapsed" 4b-is displayed on the display device 4.
The display of 5 is cancelled | released, and the patient information regarding the patient C is displayed instead. Further, the timer circuit 40 resets the time measurement. Further, in the processor 31, the examination start time (AM
10:55) and the examination start time (AM 11:25) of the patient C who is the next examinee, that is, the required examination time (30
Minute) is calculated, and new counting by the timer circuit 40 is started. When the operator starts an intravascular examination and starts X-ray exposure, this is detected by the first detector 36, and a signal to that effect is sent to the indicator 38. Here, when the required inspection time of 30 minutes elapses before the intravascular inspection is completed, a signal to that effect is sent from the timer circuit 40 to the processing processor 31, and the processing processor 3 which has received the signal.
1 displays on the display device 4 a "warning that the predetermined inspection time has elapsed" 4b-5. The warning display is continued until the surgeon selects the examinee ID of the new examinee. When the examinee ID of the new examinee is selected, the warning display is canceled. Then, the examination will be transferred to the next examinee.

Next, another example of the above-described control flow will be described along with the flow of actual patient replacement. In this example, like the actual examination reservation system, the examination reservation time of each patient is managed, and even if the examination that should be performed according to this examination reservation time passes the examination reservation time of the next patient, If it is still continued, a "warning that the next scheduled inspection time has arrived" is displayed. FIG. 13 shows a time chart for explaining the flow. However, in the figure, in order to simplify the explanation,
The timer circuit 4 starts from the time when the examinee ID is selected.
Timekeeping by 0 will be started.

First, when the operator confirms the name of the patient A who is the first examinee from the examinee list displayed on the display device 4 and selects the examinee ID, the operator displays the name on the display device 4. Displays the patient information regarding this patient A. Also,
At the same time, the processor 31 starts the time counting by the timer circuit 40 until the examination reservation time (AM 10:30) of the patient B who is the next examinee. When the operator starts an intravascular examination and starts X-ray exposure, this is detected by the first detector 36, and a signal to that effect is sent to the indicator 38. Here, the intravascular examination is completed before the next examination reservation time, AM 10:30,
When the X-ray exposure is stopped, the X-ray fluoroscopic image recorded during the examination is stored in the image recording unit 35 in association with the examinee ID. Further, when the patient A gets off the bed 2, this is detected by the second detector 37, and a signal to that effect is sent to the indicator 38. The indicator 38 which received this,
The first detector 36 and the second detector 37 are ANDed and a signal is issued to the processor 31. In response to this, the processor 31 displays, for example, a "warning to select the examinee ID of the patient B who is the next examinee B" 4a-3 in the examinee list displayed on the display unit 4.

Further, when the operator selects the examinee ID of the patient B who is the next examinee, the display unit 4 indicates that the "examinee ID of the next examinee is selected." The display of the warning "4a-3" is canceled and the patient information regarding the patient B is displayed instead. Further, the timer circuit 40 resets the time measurement. Further, the processor 31 starts a new time measurement by the timer circuit 40 until the examination start time (AM11: 00) of the patient C who is the next examinee. When the operator starts an intravascular examination and starts X-ray exposure, this is detected by the first detector 36, and a signal to that effect is sent to the indicator 38. Here, if the intravascular examination is finished before the next scheduled examination time of 11:00 AM and the X-ray exposure is stopped, the X-ray fluoroscopic image recorded during the examination is presented to the examinee. The image is stored in the image recording unit 35 in association with the ID. Further, when the patient B gets off the bed 2, this is detected by the second detector 37, and a signal to that effect is sent to the indicator 38. The indicator 38 which has received this takes the AND of the first detector 36 and the second detector 37, and the processor 3
Signal to 1. The processor 31 which received this
For example, in the list of examinees displayed on the display unit 4, "warning of selecting the examinee ID of the patient C who is the next examinee" 4a-3 is displayed.

Further, when the operator selects the examinee ID of the patient C who is the next examinee, the display unit 4 indicates that the "examinee ID of the next examinee is selected." The display of the warning "4a-3" is canceled and the patient information regarding the patient C is displayed instead. Further, the timer circuit 40 resets the time measurement. Further, the processing processor 31 starts a new time measurement by the timer circuit 40 until the examination start time (AM11: 30) of the patient D who is the next examinee. When the operator starts an intravascular examination and starts X-ray exposure, this is detected by the first detector 36, and a signal to that effect is sent to the indicator 38. Here, before the end of the intravascular examination, when the examination start time AM11: 30 of the patient D who is the next examinee arrives, the timer circuit 40 sends a signal to that effect to the processing processor 31, The processor 31 which received this
However, the display device 4 displays "warning that the next inspection appointment time has arrived". It should be noted that this warning display is continued until the operator selects a examinee ID of a new examinee. Then, when the intravascular examination is finished and the X-ray exposure is stopped, the X-ray fluoroscopic image recorded during the examination is stored in the image recording unit 35 in association with the examinee ID. Further, when the patient C descends from the bed 2, this is detected by the second detector 37, and a signal to that effect is sent to the indicator 38. The indicator 38 which has received this takes the AND of the first detector 36 and the second detector 37, and the processor 3
Signal to 1. The processor 31 which received this
For example, in the list of examinees displayed on the display unit 4, “warning for selecting the examinee ID of the patient D who is the next examinee” 4a-3 is further displayed. Then, when the examinee ID of the patient D who is the next examinee is selected, these warning displays are canceled, and the examination of the next examinee is started.

As described above, according to the present invention, if the examinee ID of the next examinee is not input even though the examination of one examinee is completed, the required examination is started from the start of photographing. When the time elapses, that is, when the scheduled examination start time of the next examinee arrives, the warning display is automatically performed. Therefore, as in the conventional case, by continuing the examination of other examinees without selecting the examinee ID, it is possible to eliminate a mistake file that causes a discrepancy in the correspondence between the captured image and the examinee. ,
In particular, it is possible to prevent work mistakes at the time of group medical examinations in which medical staff are extremely busy. Therefore, it is possible to improve the work efficiency of the medical staff without causing a backtracking work at the time of image interpretation.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in various forms. For example, instead of connecting to the examination reservation system, by providing a terminal for managing patient information and examination reservation information of the examinee, the examinee list and patient information can be obtained without displaying the network and displayed on the display device. You may decide to do it. In such a case, a means for acquiring patient information from an ID card, an IC card, a bar code or the like may be further provided. Further, the present invention is not limited to fluoroscopy in an X-ray diagnostic apparatus, but imaging in an X-ray diagnostic apparatus, and further an X-ray CT apparatus or a magnetic resonance imaging apparatus (MRI).

Alternatively, for example, a plurality of X-ray image detectors may be arranged in a matrix, which is composed of a laminated body in which a fluorescent plate and a semiconductor photosensor are optically coupled.

The bed 2 can be tilted, for example, between a vertical position and a horizontal position, and the table 21 on which the patient P is placed.
I support you. The top plate 21 can be moved in a plane while being supported by the bed 2, and one end of the top plate 21 is provided with a step 22 for supporting the examinee in a standing position. Further, the column portion (the hatched portion shown in FIG. 5) has a structure shown in FIG.
As shown in (a) and (b), a load sensor 23 or a strain sensor 24 is provided as means for detecting the change of the examinee P, specifically, the getting on / off of the examinee P. An allowable load range is set for the load sensor 23 and the strain sensor 24, and if the allowable load range is within this allowable load range, the sheets and accessories (drip board, mat, etc.) necessary for the inspection are not to be examined. Separately, it can be placed on the bed 2.

The controller 3 has a central function for controlling the entire X-ray diagnostic apparatus, and has a processor 31 having a CPU as a main element and a memory 32 necessary for processing.
Etc. are provided and are organically connected to each of the following components including the imaging device 1 and the bed 2 via a bus line 33. That is, the control device 3 inputs various instructions and numerical information for controlling the X-ray exposure conditions, the imaging direction, the up and down movement of the bed 2, the position of the tabletop 21, and the like. A mouse for selecting the examinee ID,
An input unit 3a having a trackball, a keyboard, etc., a command unit 3b having a switch, a microphone, etc. for instructing the start and end of imaging, and patient information displayed on the display unit 4 can be freely switched in the order of scheduled examination times. A switch unit 3c having a switch, a microphone, etc., a examinee ID registration unit 34 for registering the examinee ID, and an image recording unit 35 for recording the collected diagnostic images of the examinee, which are respectively connected to the bus line 33. Has been done. The command unit 3b is shown in FIG.
As shown in FIG. 3, for example, a foot switch including a shooting start switch 3b-1 for starting shooting by the shooting device 1 and a shooting end switch 3b-2 for ending shooting by the shooting device 1 may be used. Good. Further, as shown in FIG. 17, the switching unit 3c switches, for example, the preview switch 3c-1 for switching the patient information to the previous one in the order of the examination reservation time and the preview switch 3c-1 for the patient information one after the order of the examination reservation time. A foot switch or the like including the next switch 3c-2 and the confirmation switch 3c-3 for confirming the patient information of the examinee may be used. Furthermore, the command unit 3b and the switching unit 3c described above may be a voice input device such as a microphone when the control device 3 supports a voice recognition function.

Further, in the control device 3, the first detector 36 for detecting that the photographing by the photographing device 1 is started by the command from the command part 3b, and the photographing device 1 by the command from the command part 3b. When a detection signal is obtained from both the first detector 36 and the second detector 37 that detect the end of the image capturing by the display device 4, An indicator 38 for issuing a signal for instructing to display the patient information of a new examinee is provided and is connected to each bus line 33.

Further, the control device 3 is connected to an examination reservation system S for managing patient information of the examinee and examination reservation time, and the processor 31 is connected to the control processor 3 every time the examination is completed.
Upon receiving a signal from the indicator 38, the examination reservation system S calls the patient information of the next examinee and automatically displays it on the display device 4. Further, this patient information can be freely switched in the order of the examination reservation time by operating the switching unit 3c described above.

The first detector 36 is the load sensor 2
3, or after the strain sensor 24 confirms that the examinee P is placed on the bed 2, a command signal for urging X-ray exposure is issued from the command unit 3b to the imaging apparatus 1. Anything that can detect

The second detector 37 is the load sensor 2
3 or the strain sensor 24 confirms that the examinee P has stepped off the bed 2, and then issues a command signal for prohibiting X-ray exposure from the command unit 3b to the imaging apparatus 1. Anything that can be detected may be used.

In the examination room, in addition to the photographing device 1 and the bed 2, a display device 4 for displaying an image at the time of photographing is provided, and the operator can see the image displayed on the display device 4. However, the positioning suitable for shooting is performed. Further, the display device 4 displays patient information regarding the examinee during the examination.

Further, in the examination room, in place of the display device 4, or in addition to the display device 4, a voicing device 5, that is, a speaker may be provided. In such a case, the patient information relating to the examinee can be obtained by using the voicing device 5.
The operator will be notified by the sound emitted from.

Next, using the X-ray diagnostic apparatus configured as described above, a procedure in which an intravascular examination, which is an example of so-called X-ray fluoroscopy, is repeatedly performed on different patients will be described.
The state of the load applied to the bed at that time is shown in FIG.
This will be described with reference to the flowchart shown in FIG.

First, in step 31, the operator confirms the name of the examinee who is to be examined first on the day from the examinee list displayed on the display device 4, and inputs the examinee ID by the input unit 3a. Select by operation. Then, the display device 4 displays the patient information regarding the examinee. The previous examinee list 4a is as shown in FIG. 7, and the examinee ID 4a-1 and the examinee name 4a-2.
It consists of and. Incidentally, regarding the examinees who have already undergone the examination, they are automatically deleted from the examinee list 4a or displayed in the patient information 4b described later (for example, "examined"). Is being done. Further, the patient information 4b is as shown in FIG. 8, and the examination reservation time 4b-1
And the examinee name 4b-2, the examinee ID 4b-3, and the order number 4b-4 (the examination number issued for each examination). In addition, this patient information 4b
In addition to these, the date of birth, sex, age, health record number, etc. of the examinee may be included as necessary. Also,
At this time, the bed 2 is in a state where the load is zero. Then, in step 32, the examinee is placed on the bed 2. At this time, the bed 2 is loaded by the examinee, and the load sensor 23,
Alternatively, this is detected by the strain sensor 24, and a signal to that effect (indication that the examinee P is placed on the bed 2) is sent to the first detector 36. Furthermore, as step 33,
After the operator confirms that the examinee P is placed on the bed 2, when the command unit 3b issues a command signal to the imaging apparatus 1 to start the X-ray exposure, the signal to that effect is first. Detector 36
Sent to. Receiving this, the first detector 36 sends a signal to that effect (a signal that imaging has started) to the indicator 38. At the same time, as step 34, the X by the photographing device 1
The exposure of the ray is started. For the intravascular examination, the operator uses the X-ray tube 1.
By rotationally driving the support arm 13 having the one- and two-dimensional X-ray detectors 12, the support arm 13 is positioned in the vicinity of the diagnostic site to be seen through, and thereafter, the see-through operation, that is, continuous X-ray exposure is started. You can get started by doing This intravascular examination is carried out while confirming the situation inside the blood vessel from various directions while changing the direction of the support arm 13. And
In step 35, the operator issues a command signal from the command unit 3b to the imaging apparatus 1 to stop the X-ray exposure upon completion of the intravascular examination, and a signal to that effect is sent to the second detector 37. At the same time, as step 36, the X-ray exposure by the imaging device 1 is stopped. At this time, the X-ray fluoroscopic image recorded during the examination is stored in the image recording unit 35 in association with the examinee ID. Then, in step 37, after the operator pulls out the examination tube from the examinee P, the examinee P is unloaded from the bed 2. At this time, the bed 2 is in a state in which the load by the examinee is removed, that is, the load is zero, and the load sensor 23 or the strain sensor 24
This is detected by and a signal to that effect is sent to the second detector 37.

The above steps show the basic procedure for the intravascular examination. However, step 3
In 1, when the operator forgets to perform the operation of selecting the examinee ID of the next examinee, the examination of the next examinee will be carried out with the previous examinee ID. A mistake occurs in setting the examinee ID, and a mistake file is generated. Therefore, the present invention detects a passenger getting on and off a bed by a load sensor or a strain sensor provided on the bed, judges the start and end of the examination from the detection result, and at the end of the examination, the operator next Examinee's Examinee ID
It is assumed that the patient information of the next examinee is automatically displayed on the display device 4 without performing the operation of selecting.

Description will be continued after step 37. further,
As a step 38, the second detector 37 that has received this
Sends a signal to that effect (a signal that the inspection has been completed) to the indicator 38. The indicator 38 which received this takes the AND of the first detector 36 and the second detector 37 to display the patient information 4b regarding the next examinee on the display unit 4 on the processor 31. Send an order. Receiving this, the processor 31 calls the patient information 4b regarding the next examinee from the examination appointment system 4 and automatically displays it on the display unit 4 in step 39. Incidentally, for example, step 39
When there is an error (misalignment) in the patient information displayed on the display unit 4, the patient information is sequentially switched by the operation of the switching unit 6 to display appropriate patient information.

Then, the operator is displayed on the display device 4,
After confirming the patient information of the examinee to be examined next, the operations from step 32 to step 39 are repeated for the next examinee.

As described above, according to the present invention, the load sensor or the strain sensor included in the bed is used to detect whether the examinee is getting on or off the bed, and the start and end of photographing are determined based on the detection result. At the end of imaging, the operator automatically displays the patient information of the next examinee on the display device without performing the operation of selecting the examinee ID of the next examinee, and further, the operator receives the examination. Since the next imaging is started after confirming the patient information of the operator, the operation of the operator can be reduced and the patient information can be reliably switched. Therefore, the operation of the operator is reduced and, unlike the conventional case, the selection of the examinee ID is not performed,
By continuing the examination of other examinees, it is possible to eliminate a mistake file that causes discrepancies in the correspondence between the captured image and the examinee, and it is possible to prevent work mistakes during group examinations that make medical staff especially busy. . Therefore, it is possible to improve the work efficiency of the medical staff without causing a backtracking work at the time of image interpretation.

Further, according to the present invention, since the display device for displaying the patient information regarding the examinee and the command section for instructing the start and end of the photographing by the photographing device are provided in the examination room, the operator can be in the examination room. Then, the patient information can be confirmed, and the next examination can be started on the spot. Therefore, it is possible to support the test execution by a small number of people.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in various forms. For example, instead of connecting to the examination reservation system, by providing a terminal for managing patient information and examination reservation information of the examinee, the examinee list and patient information can be obtained without displaying the network and displayed on the display device. You may decide to do it. In such a case, a means for acquiring patient information from an ID card, an IC card, a bar code or the like may be further provided.
