Abstract
A medical examination and treatment apparatus includes a robot operable to control a tool, and an internal position-determination system to measure a position of the tool by determining a setting of adjusting elements of the robot. The apparatus further includes an external position-determination system to measure the position of the tool, and a position monitoring system to compare the position of the tool determined by the internal position-determination system with the position of the tool determined by the external position-determination system. A mobility of the tool is restricted if an adjustable threshold relating to deviations between position measurements is exceeded.
Claims23
A medical examination and treatment apparatus, the apparatus comprising:
- a robot operable to move a tool, the robot comprising an adjusting element attached to the tool;
- an internal position-determination system to measure a position of the tool by determining a setting of the adjusting element of the robot, the internal position-determination system being internal to the robot in a same room as the tool and robot;
- an external position-determination system to measure directly the position of the tool while the tool is in a same location when the internal position-determination system measures the position of the tool, the external position-determination system being independent of the robot;
- and
- a position monitoring system to compare the position of the tool determined by the internal position-determination system with the position of the tool determined by the external position-determination system,
- wherein a mobility of the tool is restricted by restricting the movement of the adjusting element of the robot if an adjustable threshold relating to a deviation between position measurements determined by the comparison is exceeded, and
- wherein the external position-determination system is disposed on the tool and in the room.
A method for operating a medical examination and treatment apparatus, the method comprising:
- providing a tool to perform a medical examination or treatment, the tool being moved by a robot connected to a bottom surface of the tool;
- measuring a position of the tool with an internal position-determination system by determining a setting of the robot, the internal position-determination system being internal to the robot in a same room as the patient bed and robot;
- measuring directly the position of the tool with an external position-determinationsystem while the tool is in a same location when the internal position-determination system measures the position of the tool, the external position-determination system being independent of the robot and disposed on the bottom surface of the tool in the room;
- and
- comparing the position of the tool determined by the internal position-determination system with the position of the tool determined by the external position-determination system,
- wherein a mobility of the tool is restricted by restricting the movement of the adjusting element of the robot if an adjustable threshold relating to a deviation between position measurements determined by the comparison is exceeded.
