Abstract

An operation device comprises a detector configured to detect an operation on a virtual switch by an operator to operate an X-ray irradiation in an X-ray diagnosis apparatus, wherein the virtual switch is virtually set at a position settled relatively with respect to the operator and output circuitry configured to output a detection result of the operation detected by the detector to the X-ray diagnosis apparatus to be operated. This device eliminates the need for looking away from a display monitor every time the operator operates the X-ray diagnosis apparatus.

First claim

The invention claimed is:

1. An operation device, comprising:
a detector configured to detect an operation on a virtual switch by an operator to operate an X-ray irradiation in an X-ray diagnosis apparatus, wherein the virtual switch is impalpable and virtually set at a position settled relatively with respect to the operator; and
output circuitry configured to output a detection result of the operation detected by the detector to the X-ray diagnosis apparatus to be operated,
wherein the virtual switch set at the position settled relatively with respect to the operator is a virtual foot switch, which is subject to a stepping operation executed by the operator, and
the detector is further configured to determine that the stepping operation is executed when a pressure equal to or greater than a threshold value is detected at a pedal position of the virtual foot switch after a foot of the operator moves vertically.

2. The operation device according to claim 1 , wherein:
the detector is further configured to detect the stepping operation on the virtual foot switch executed by the operator; and
the output circuitry is further configured to output the detection result of the stepping operation detected by the detector to the X-ray diagnosis apparatus.

3. The operation device according to claim 1 , wherein the operation device is further configured to be worn on the operator to operate the X-ray irradiation in the X-ray diagnosis apparatus.

4. The operation device according to claim 3 , further comprising a position detector configured to detect a position of the operation device.

5. The operation device according to claim 1 , further comprising a vibration device configured to vibrate in accordance with a position of a body portion of the operator for the operation on the virtual switch.

6. The operation device according to claim 5 , wherein the vibration device is further configured to vibrate when the body portion of the operator is at an operational position at which the virtual switch is operable.

7. The operation device according to claim 6 , wherein the operational position at which the virtual switch is operable is at and/or above the pedal position at which a pedal of the virtual switch is operable.

8. The operation device according to claim 1 , wherein the output circuitry is further configured to output the detection result of the operation detected by the detector to an operation device control circuitry provided in the X-ray diagnosis apparatus.

9. The operation device according to claim 8 , wherein the output circuitry is further configured to output the detection result of the operation detected by the detector to the operation device control circuitry through wireless communication.

10. An X-ray diagnosis system, comprising:
an X-ray diagnosis apparatus configured to irradiate X-ray X-rays to a subject to obtain a diagnostic image of the subject; and
an operation device configured to operate an X-ray irradiation in the X-ray diagnosis apparatus,
wherein the operation device comprises:
a detector configured to detect an operation on a virtual switch by an operator to operate the X-ray irradiation in the X-ray diagnosis apparatus, wherein the virtual switch is impalpable and virtually set at a position settled relatively with respect to the operator; and
output circuitry configured to output a detection result of the operation detected by the detector to the X-ray diagnosis apparatus to be operated,

wherein the virtual switch set at the position settled relatively with respect to the operator is a virtual foot switch, which is subject to a stepping operation executed by the operator, and
the detector is further configured to determine that the stepping operation is executed when a pressure equal to or greater than a threshold value is detected at a pedal position of the virtual foot switch after a foot of the operator moves vertically.

11. The X-ray diagnosis system according to claim 10 , wherein the operation device is further configured to be worn on the operator to operate the X-ray irradiation in the X-ray diagnosis apparatus.

12. The X-ray diagnosis system according to claim 11 , further comprising a position detector configured to detect a position of the operation device.

13. The X-ray diagnosis system according to claim 10 , further comprising a vibration device configured to vibrate in accordance with a position of a body portion of the operator for the operation on the virtual switch.

14. The X-ray diagnosis system according to claim 13 , wherein the vibration device is further configured to vibrate when the body portion of the operator is at an operational position at which the virtual switch is operable.

15. The X-ray diagnosis system according to claim 10 , further comprising a display monitor configured to visually display a positional relation between the virtual switch and the body portion of the operator for the operation on the virtual switch.

16. The X-ray diagnosis system according to claim 10 , wherein a warning is given to the operator when the position of the virtual switch interferes with other peripheral apparatus.

17. The X-ray diagnosis system according to claim 10 , further comprising an operation device control circuitry configured to set the virtual switch at the position settled relatively with respect to the operator.

18. The X-ray diagnosis system according to claim 17 , wherein the operation device control circuitry is further configured to hold information on an operational setting for the virtual switch for each operator.
