4A and 4B are front views for explaining how to operate the X-ray irradiation instruction device 10 worn on the hand. FIG. 5 is a side perspective view for explaining how to operate the X-ray irradiation instruction device 10 worn on the hand.

As shown in FIGS. 4A, 4B, and 5, the finger support part 11 of the X-ray irradiation instruction device 10 is one of the middle finger, the ring finger, and the little finger (in FIG. 4, the second joint of the ring finger ( The pointing device main body 12 is attached to the hand of the operator D by being inserted between the PIP joint) and the third joint (MP joint). Further, the pointing device main body 12 can move the ball of the finger when one of the middle finger, the ring finger, and the little finger is bent with the finger support portion 11 attached to the finger (for example, the ring finger). It is configured such that an irradiation instruction switch 121 (for example, “perspective SW”) is arranged within the range. Specifically, the pointing device main body 12 has a size and shape that fit within the palm of the hand when the finger support portion 11 is attached to the finger. More preferably, the palm area is an area provided near the roots of the middle finger, ring finger, and little finger on the palm.

In this way, the pointing device main body 12 has a size and shape that can be accommodated within the range of the four finger bases in a state where the finger support part 11 is attached to the finger. With 11 inserted, five fingers can be freely handled. Therefore, the operator D can perform operations such as operating the catheter C with the thumb and forefinger while instructing X-ray irradiation (that is, pressing the button of the irradiation instruction switch 121) with the other fingers.

When the button of the irradiation instruction switch 121 is pressed (shown in FIG. 4B) from the state shown in FIG. 4A in which the catheter C is operated with the thumb and forefinger, a signal indicating the start of X-ray irradiation (irradiation A start signal) is generated, and the irradiation start signal is sent to the processing circuit 24 of the image generating device 20 via the transmission circuit 122 . X-ray irradiation from the X-ray irradiation device 22 is started under the control of the processing circuit 24, and X-ray irradiation is continued. When the button of the irradiation instruction switch 121 is released (shown in FIG. 4A), a signal indicating the end of X-ray irradiation (irradiation end signal) is generated, and the irradiation end signal is transmitted through the transmission circuit 122 to generate an image. It is sent to the processing circuitry 24 of the device 20 . Then, the X-ray irradiation from the X-ray irradiation device 22 is terminated under the control of the processing circuit 24 .

Alternatively, from the state shown in FIG. 4A in which the catheter C is operated with the thumb and forefinger, the button of the irradiation instruction switch 121 is pressed (shown in FIG. 4B) and released (shown in FIG. 4A). ), an irradiation start signal is generated and sent to the processing circuit 24 of the image generating device 20 via the transmission circuit 122 . X-ray irradiation from the X-ray irradiation device 22 is started under the control of the processing circuit 24, and X-ray irradiation is continued. From the state shown in FIG. 4(A), when the button of the irradiation instruction switch 121 is pressed again (shown in FIG. 4(B)) and released (shown in FIG. 4(A)), an irradiation end signal is generated. An irradiation end signal is sent to the processing circuit 24 of the image generating device 20 via the transmission circuit 122 . Then, the X-ray irradiation from the X-ray irradiation device 22 is terminated under the control of the processing circuit 24 . In this case, X-ray irradiation can be performed without continuously pressing the button of the irradiation instruction switch 121. Therefore, when X-ray irradiation is continued for a long time, there is an advantage that the burden on the finger of the operator D is reduced. There is The irradiation start signal may be generated by pressing the button of the irradiation instruction switch 121 once (single action), or by pressing the button of the irradiation instruction switch 121 twice (double action). A start signal may be generated. In the latter case, by setting a predetermined threshold for generation of the detection signal, generation of the irradiation instruction signal due to unintended pressing can be prevented.

Here, the X-ray irradiation instruction can be issued in any one mode among a plurality of imaging methods (modes) executable by the image generation device 20 . For example, modes include a fluoroscopy mode, an imaging mode, a fluoroscopy acquisition mode, a one-shot mode, and the like. Here, the fluoroscopy mode refers to an imaging method in which relatively weak X-rays are irradiated and image data is acquired as a moving image and displayed on the display 28 without the purpose of storing image data. The imaging mode is intended to store image data, and means an imaging method in which relatively strong X-rays are applied to obtain image data as a moving image and stored in the storage circuit 25 . The fluoroscopy acquisition mode is an imaging method for the purpose of storing image data, in which relatively weak X-rays are irradiated to obtain image data as a moving image and stored in the storage circuit 25 . The one-shot mode is an imaging method in which relatively strong X-rays are applied to acquire image data as a still image and stored in the memory circuit 25 for the purpose of storing image data.

Since the image generating apparatus 20 can employ various imaging methods to irradiate X-rays, by allocating one of a plurality of modes to the irradiation instruction switch 121, it is possible to perform X-ray irradiation according to each mode. X-ray irradiation instructions can be given. For example, when the fluoroscopy mode is assigned to the irradiation instruction switch 121, when the button of the irradiation instruction switch 121 is pressed, an irradiation start signal is generated to irradiate X-rays for fluoroscopy, or When the button of the switch 121 is pressed and released, an irradiation start signal is generated and X-rays for fluoroscopy are irradiated. Further, for example, when the one-shot mode is assigned to the irradiation instruction switch 121, when the button of the irradiation instruction switch 121 is pressed, an irradiation start signal is generated and the one-shot X-ray is irradiated once. Alternatively, when the button of the irradiation instruction switch 121 is pressed and released, an irradiation start signal is generated and one-shot X-ray is irradiated once.

According to the X-ray irradiation instruction device 10, since the instruction device main body 12 is attached to the hand by the finger support portion 11, the operator D can easily perform X-ray irradiation with the fingers of the instruction device main body 12, which does not need to be held by the operator D. of irradiation instructions. Further, according to the X-ray irradiation instruction device 10, compared with a configuration having a foot switch for giving an X-ray irradiation instruction, the operator does not need to visually check his/her feet, and the stress of the operator D can be reduced.

(First modification)
In the above description, the case where the irradiation instruction switch 121 of the X-ray irradiation instruction device 10 includes one switch element has been described as an example, but the present invention is not limited to this case. The irradiation instruction switch 121 may include a plurality of switch elements arranged in parallel. The irradiation instruction switch 121 includes a plurality of switch elements corresponding to a plurality of imaging methods, respectively. A signal indicating the end (irradiation end signal) is generated.

FIGS. 6A and 6B are front views for explaining the operating method of the first modified example of the X-ray irradiation instruction device 10 worn on the hand. 6A shows a state in which the button of the irradiation instruction switch 121 is not pressed, and FIG. 6B shows a state in which the button of the irradiation instruction switch 121 is pressed.

As shown in FIGS. 6A and 6B, the irradiation instruction switch 121 has three switch elements. One of the three switch elements is assigned a fluoroscopy mode, one is assigned an imaging mode, and one is assigned a fluoroscopy acquisition mode. For example, when the operator D instructs X-ray irradiation in the fluoroscopy mode, he bends his middle finger and presses the switch element button to which the fluoroscopy mode is assigned. For example, when the operator D instructs X-ray irradiation in the imaging mode, he bends his ring finger and presses the button of the switch element to which the imaging mode is assigned. For example, when the operator D instructs X-ray irradiation in the fluoroscopic collection mode, he bends his little finger and presses the button of the switch element assigned to the fluoroscopic collection mode. Note that the number of switch elements provided in the irradiation instruction switch 121 is not limited to three, and may be two or four or more.

When the irradiation instruction switch 121 includes a plurality of switch elements, the irradiation instruction switch 121 includes a switch element for generating an irradiation start signal and an irradiation end signal corresponding to the mode, and a switch element for switching the function of the switch element. may contain For example, if the irradiation instruction switch 121 includes a first switch element that generates an irradiation start signal and an irradiation end signal, and a second switch element that switches the function of the switch element, pressing the second switch element And by releasing the pressing, the function of the first switch element is cyclically switched in the order of fluoroscopy mode, imaging mode, fluoroscopy acquisition mode, and one-shot mode according to the sequence.

According to the first modification of the X-ray irradiation instruction device 10, since the instruction device main body 12 is attached to the hand by the finger support portion 11, the operator D does not need to hold the instruction device main body 12. , it is possible to easily instruct X-ray irradiation over a plurality of modes. Further, according to the first modified example of the X-ray irradiation instruction device 10, similarly to the effects described above, compared to a configuration including a foot switch for giving an X-ray irradiation instruction, visual observation of the feet is eliminated. Operator D's stress can be reduced.

(Second modification)
In the above description, the case where the irradiation instruction switch 121 (or each switch element of the irradiation instruction switch 121) of the X-ray irradiation instruction apparatus 10 is a one-stage switch has been described as an example, but the present invention is not limited to this case. The irradiation instruction switch 121 may be a multistage switch that can detect the depth of depression in multiple stages.

By adopting a multistage switch, the irradiation instruction switch 121 can issue an X-ray irradiation instruction over a plurality of modes. For example, the irradiation instruction switch 121 can employ a two-step switch (for example, for both fluoroscopy and imaging) as a multi-step switch. In this case, when the button of the irradiation instruction switch 121 is half-pressed from the state shown in FIG. 4A in which the catheter C is operated with the thumb and forefinger, an irradiation instruction signal for fluoroscopy is generated. An irradiation instruction signal is sent to the processing circuit 24 of the image generation device 20 via the transmission circuit 122 . X-ray irradiation for fluoroscopy from the X-ray irradiation device 22 is started under the control of the processing circuit 24, and X-ray irradiation for fluoroscopy is continuously performed. When the button of the irradiation instruction switch 121 is released, an irradiation end signal for fluoroscopy is generated, and the irradiation end signal for fluoroscopy is sent to the processing circuit 24 of the image generating apparatus 20 via the transmission circuit 122 . Then, the X-ray irradiation for fluoroscopy from the X-ray irradiation device 22 is terminated under the control of the processing circuit 24 .

On the other hand, when the button of the irradiation instruction switch 121 is fully pressed from the state shown in FIG. 4A in which the catheter C is operated with the thumb and forefinger, an irradiation start signal for imaging is generated. An irradiation instruction signal is sent to the processing circuit 24 of the image generation device 20 via the transmission circuit 122 . X-ray irradiation for imaging from the X-ray irradiation device 22 is started under the control of the processing circuit 24, and X-ray irradiation for imaging is continued. When the button of the irradiation instruction switch 121 is released, an irradiation end signal for imaging is generated, and the irradiation end signal for imaging is sent to the processing circuit 24 of the image generating device 20 via the transmission circuit 122 . Then, X-ray irradiation for imaging from the X-ray irradiation device 22 is terminated under the control of the processing circuit 24 .

By adopting a multistage switch as the irradiation instruction switch 121 in this way, the irradiation instruction switch 121 can issue an X-ray irradiation instruction over a plurality of modes. Further, according to the multistage switch, it is also possible for the operator D to freely customize the assignment of the mode to each stage (each depression depth) of the multistage switch.

The technical idea of the second modified example of the X-ray irradiation instruction device 10 can also be applied to the technical idea of the above-described first modified example. Specifically, the irradiation instruction switch 121 of the X-ray irradiation instruction apparatus 10 has a plurality of switch elements, and a multistage switch can be employed for all or part of them.

According to the second modification of the X-ray irradiation instruction device 10, since the instruction device main body 12 is attached to the hand by the finger support portion 11, the operator D does not need to hold the instruction device main body 12. , it is possible to easily instruct X-ray irradiation over a plurality of modes. In addition, according to the second modification of the X-ray irradiation instruction device 10, similarly to the effects described above, compared to a configuration including a foot switch for giving an X-ray irradiation instruction, visual observation of the feet is eliminated. Operator D's stress can be reduced.

(Third modification)
In the above description, the irradiation instruction switch 121 (or each switch element of the irradiation instruction switch 121, or each stage of the multistage switch) is assigned to switch the functions of other switches, but the present invention is limited to that case. isn't it. For example, the X-ray irradiation instruction device 10 may be configured to switch mode allocation to the irradiation instruction switch 121, that is, to switch the function of the irradiation instruction switch 121 without depending on switch operation.

FIG. 7 is a schematic diagram showing the configuration of an angiography apparatus 1 provided with a third modification of the X-ray irradiation instructing device 10. As shown in FIG.

The instruction device main body 12 includes an irradiation instruction switch 121 , a transmission circuit 122 , a power supply device 123 , and a vibration sensor 124 . In FIG. 7, the same members as those of the angiography apparatus 1 shown in FIG.

The vibration sensor 124 detects vibrations (translational movements in three orthogonal axial directions) of the X-ray irradiation instruction device 10 in a three-dimensional space. As the vibration sensor 124, a three-axis acceleration sensor (for example, a three-axis acceleration sensor) in three-dimensional space, a gyro sensor that detects three-axis angular velocity in three-dimensional space, and a three-axis geomagnetism sensor in three-dimensional space. A magnetic sensor (for example, a triaxial geomagnetic sensor), etc. can be mentioned. Also, the vibration sensor 124 may be a so-called 9-axis sensor. When the mode switching operation is performed by shaking the X-ray irradiation instruction device 10, the vibration sensor 124 detects when the vibration of the X-ray irradiation instruction device 10, for example, the magnitude of acceleration exceeds a predetermined threshold value. A signal is generated and sent to processing circuitry 24 via transmission circuitry 122 . When the processing circuit 24 receives the detection signal from the X-ray irradiation instruction device 10, it determines that there has been a mode switching operation. Unintended mode switching can be prevented by setting a predetermined threshold for generation of the detection signal.

First, when the vibration sensor 124 generates a detection signal corresponding to the mode switching operation, it sends the detection signal to the processing circuit 24 of the image generating device 20 via the transmission circuit 122 . When receiving the detection signal, the processing circuit 24 determines that there has been a mode switching operation, and switches the function of the irradiation instruction switch 121 from the first mode to the second mode according to the sequence. When the processing circuit 24 receives an irradiation instruction signal via the transmission circuit 122 in the second mode after switching, the processing circuit 24 controls the X-ray irradiation device 22 to perform X-ray irradiation for the second mode. . On the other hand, when the processing circuit 24 further receives a detection signal via the transmission circuit 122 in the second mode after switching, the processing circuit 24 changes the function of the irradiation instruction switch 121 from the second mode according to the sequence. Switch to the third mode (or the first mode).

The processing circuit 24 cyclically switches the function of the irradiation instruction switch 121 according to a predetermined sequence each time it receives the detection signal. For example, in the sequence, each time a detection signal is received from the X-ray irradiation instruction device 10, the function of the irradiation instruction switch 121 is switched to fluoroscopy mode, imaging mode, fluoroscopy acquisition mode, and one-shot mode in order. This sequence is for returning the function of the irradiation instruction switch 121 to the fluoroscopy mode upon reception of the detection signal. A sequence is set for each protocol or program. The sequence may be set when the angio apparatus 1 is manufactured and shipped, or may be freely set by the operator D after installation. Thereby, the operator D can easily switch modes using the X-ray irradiation instruction device 10 without memorizing a complicated operation method.

Secondly, when the vibration sensor 124 continuously generates a plurality of detection signals (within a predetermined period) according to the mode switching operation, the plurality of detection signals are transmitted through the transmission circuit 122 to generate an image. It is continuously sent to the processing circuitry 24 of the device 20 . When the processing circuit 24 receives a plurality of consecutive detection signals, it determines that there has been a mode switching operation according to the number of times, and switches the function of the irradiation instruction switch 121 from the first mode to the corresponding mode according to the sequence. When the processing circuit 24 receives an irradiation instruction signal via the transmission circuit 122 in the corresponding mode after switching, the processing circuit 24 controls the X-ray irradiation device 22 to perform X-ray irradiation for the corresponding mode. For example, when the processing circuit 24 receives two successive detection signals, it switches the function of the irradiation instruction switch 121 according to the sequence from the current mode to the next mode instead of the next mode. According to this, the operator D can quickly call up a desired mode by the mode switching operation, so that the working efficiency of the operator D can be further improved.

Also, the first and second methods described above may be switched by user settings.

Furthermore, the X-ray irradiation instruction device 10 or the image generation device 20 can notify the operator D of the mode type after switching when there is a mode switching operation. For example, the X-ray irradiation instruction device 10 further includes an output device (not shown), and the type of mode after switching may be output as visual information via the output device (eg, display). , speaker) to output the type of mode after switching as voice information.

According to the third modification of the X-ray irradiation instruction device 10, since the instruction device main body 12 is attached to the hand by the finger support portion 11, the operator D does not need to hold the instruction device main body 12. , it is possible to easily instruct X-ray irradiation over a plurality of modes. Further, according to the third modification of the X-ray irradiation instruction device 10, similarly to the effects described above, compared to a configuration having a foot switch for giving an X-ray irradiation instruction, visual observation of the feet is eliminated. Operator D's stress can be reduced.

For example, the pointing device main body 12 may be connected to the inside of the finger support portion 11 that can be inserted into the finger of the operator D on the fingertip side. This case will be described below.
