Abstract

According to an embodiment, an X-ray imaging device includes an irradiator, an exposure switch device, and a control device. The irradiator irradiates a subject placed on a bed with X-rays. The exposure switch device receives an operation of an operator related to X-ray irradiation. The control device controls the X-ray irradiation based on the X-rays. The exposure switch device includes a switch and an output. The switch is set on the basis of a position of the operator and detects the operation of the operator. The output outputs an operation signal based on the operation of the operator to the control device when the operation of the operator has been detected by the switch.

Claims (65)

1 . An X-ray imaging device, comprising:

an irradiator configured to irradiate a subject, placed on a bed, with X-rays;

an exposure switch device configured to receive an operation of an operator related to X-ray irradiation; and

wherein the exposure switch device comprises:

a switch set based on a position of the operator and configured to detect the operation of the operator; and

an output configured to output an operation signal based on the operation of the operator to the control device when the operation of the operator has been detected by the switch,

wherein the control device is further configured to cause the irradiator to radiate the X-rays based on the operation signal output by the exposure switch device,

wherein the switch includes

a light projector configured to generate a foot switch by projecting visible light;

a light-receiver configured to receive reflected light related to the visible light; and

a pressure sensor provided around the bed, and

wherein the switch is configured to detect the operation of the operator based on a reflected light reception result of the light-receiver and a pressure detected by the pressure sensor.

2 . The X-ray imaging device according to claim 1 , wherein the switch further includes:

a marker attached to the operator; and

an imaging device configured to image the marker,

wherein the switch is configured to detect the operation of the operator further based on movement of the marker imaged by the imaging device.

3 . The X-ray imaging device according to claim 1 , wherein the exposure switch device further includes a position detector configured to detect a position of the operator.

4 . The X-ray imaging device according to claim 1 , wherein an operation console that is operated by the operator is provided on the bed, and

wherein the exposure switch device further includes a tabletop exposure switch provided on the operation console and configured to output the operation signal to the control device according to an operation of the operator.

5 . The X-ray imaging device according to claim 1 , further comprising a notification controller configured to control a notification device configured to provide a notification of the operation of the operator on the switch while acting on senses of the operator.

6 . The X-ray imaging device according to claim 3 , wherein the position detector includes a plurality of touch sensors provided at a plurality of positions on at least one of a gantry configured to accommodate the irradiator and the bed, and configured to be able to come into contact with the operator, and

wherein the position detector is further configured to detect the position of the operator based on a touch sensor in contact with the operator among the plurality of touch sensors.

7 . The X-ray imaging device according to claim 3 , wherein the position detector includes:

a camera configured to capture an image of the operator; and

an image processor configured to process the image captured by the camera, and

wherein the position detector is further configured to detect the position of the operator based on an image processing result of the image processor.

8 . The X-ray imaging device according to claim 7 ,

wherein the switch includes a marker attached to the operator, and

wherein the position detector is configured to detect a position where the marker has been recognized as the position of the operator when the marker attached to the operator is included in the image captured by the camera.

9 . The X-ray imaging device according to claim 5 , wherein the notification device is a vibration device configured to give vibrations to the operator.

10 . An X-ray imaging system comprising:

the X-ray imaging device according to claim 5 ; and

the notification device configured to provide the notification of the operation of the operator on the switch while acting on the senses of the operator.

11 . An X-ray imaging device, comprising:

an irradiator configured to irradiate a subject placed on a bed with X-rays;

an exposure switch device configured to receive an operation of an operator related to X-ray irradiation; and

a control device configured to control the X-ray irradiation based on the X-rays,

wherein the exposure switch device comprises

a switch set based on a position of the operator and configured to detect the operation of the operator; and

an output configured to output an operation signal based on the operation of the operator to the control device when the operation of the operator has been detected by the switch,

wherein the control device is configured to cause the irradiator to radiate the X-rays based on the operation signal output by the exposure switch device,

wherein the switch includes

a light projector configured to generate a foot switch by projecting visible light;

a light-receiver configured to receive reflected light related to the visible light;

a marker attached to the operator; and

an imaging device configured to image the marker, and

wherein the switch is configured to detect the operation of the operator based on a reflected light reception result of the light-receiver and movement of the marker imaged by the imaging device.

12 . An X-ray imaging device, comprising:

an irradiator configured to irradiate a subject placed on a bed with X-rays;

an exposure switch device configured to receive an operation of an operator related to X-ray irradiation; and

a control device configured to control the X-ray irradiation based on the X-rays,

wherein the exposure switch device comprises

a switch set based on a position of the operator and configured to detect the operation of the operator; and

an output configured to output an operation signal based on the operation of the operator to the control device when the operation of the operator has been detected by the switch,

wherein the control device is configured to cause the irradiator to radiate the X-rays based on the operation signal output by the exposure switch device,

wherein the switch includes

a pressure sensor provided around the bed;

a marker attached to the operator; and

an imaging device configured to image the marker, and

wherein the switch detects the operation of the operator based on a pressure detected by the pressure sensor and a movement of the marker imaged by the imaging device.

13 . A method of controlling an X-ray imaging device, the X-ray imaging device including an irradiator configured to irradiate a subject placed on a bed with X-rays; an exposure switch device configured to receive an operation of an operator related to X-ray irradiation; and a control device configured to control the X-ray irradiation based on the X-rays, wherein the exposure switch device includes a switch set based on a position of the operator and configured to detect the operation of the operator; and an output configured to output an operation signal based on the operation of the operator to the control device when the operation of the operator has been detected by the switch, and wherein the switch includes a light projector configured to generate a foot switch by projecting visible light, a light-receiver configured to receive reflected light related to the visible light; and a pressure sensor provided around the bed,
