Method and device for controlling movement of a motorized C-arm
The invention relates to a method for controlling movement of a motorized C-arm, comprising: receiving position information of a user (U) relative to the C-arm ( 1 ), continuously receiving current position information of the C-arm ( 1 ) relative to a reference position of the C-arm, from said current position information and from the position information of the user, computing a graphical representation of the current position of the C-arm according to the user's point of view, from the computed graphical representation of the current position of the C-arm, computing a graphical representation of at least one command button suited to the current position information of the C-arm and to the user's point of view to move the C-arm in a determined direction according to a respective degree of freedom, displaying on a control panel a graphical user interface ( 7 ) comprising said computed representation ( 70 ) of the current position of the C-arm and said at least one command button ( 710 ).
1. A method for controlling movement of a motorized C-arm, comprising:
receiving position information of a user relative to the C-arm,
continuously receiving current position information of the C-arm relative to a reference position of the C-arm,
from said current position information and from the position information of the user, computing a graphical representation of the current position of the C-arm according to a user's point of view,
from the computed graphical representation of the current position of the C-arm, computing a graphical representation of at least one command button suited to the current position information of the C-arm and to the user's point of view to move the C-arm in a determined direction according to a respective degree of freedom,
displaying on a control panel a graphical user interface comprising said computed representation of the current position of the C-arm and said at least one command button.
2. The method according to claim 1 , further comprising updating the position information of the user relative to the C-arm and updating the graphical representation of the at least one command button based on said updated position information.
3. The method according to claim 1 , wherein when the C-arm is in a stop position for at least one degree of freedom, the command button of the graphical user interface and/or the respective tactile zone is disabled.
4. The method according to claim 1 , wherein the command button comprises at least one of: a color, a texture and a pictogram specific to a respective degree of freedom of the C-arm, and wherein said color, texture and/or pictogram is further displayed on the graphical representation of the C-arm.
5. The method according to claim 1 , wherein the control panel is embedded in a remote command device configured to be held by a user in the operating room.
6. The method according to claim 1 , wherein the control panel is embedded in a computer command station configured to be located in the operating room.
7. The method according to claim 1 , wherein a first control panel is embedded in a remote command device configured to be held by a user in the operating room and a second control panel is embedded in a computer command station configured to be located in the operating room and wherein when a user of the remote command device and a user of the computer command station are not on the same side of the C-arm, different graphical user interfaces are displayed on each respective first or second control panel.
8. The method according to claim 1 , wherein the position information of the user relative to the C-arm is selected from a limited group of point of views.
9. The method according to claim 8 , wherein the position information of the user relative to the C-arm is given by the user by selecting one point of view among said group.
10. The method according to claim 1 , wherein the position information of the user is obtained from position sensors arranged on the user and/or on the control panel and the C-arm.
11. A device for controlling movement of a motorized C-arm, comprising:
a control panel for displaying a graphical user interface comprising a representation of a current position of the C-arm and at least one command button for controlling a movement of the C-arm in a determined direction according to a respective degree of freedom,
a processor capable of communicating with the control panel and configured to carry out the following steps:
receiving position information of a user relative to the C-arm,
continuously receiving current position information of the C-arm relative to a reference position of the C-arm,
from said current position information and from the position information of the user, computing a graphical representation of the current position of the C-arm according to a user's point of view,
from the computed graphical representation of the current position of the C-arm, computing a graphical representation of at least one command button suited to the current position information of the C-arm and to the user's point of view to move the C-arm in a determined direction according to a respective degree of freedom,
displaying on the control panel a graphical user interface comprising said computed representation of the current position of the C-arm and said at least one command button.
12. The device according to claim 11 , wherein said control panel is embedded in a remote control device configured to be held by a user in the operating room.
13. The device according to claim 11 , wherein said control panel is embedded in a computer command station configured to be located in the operating room.
14. A surgical system comprising a motorized C-arm and the device according to claim 11 .
