Abstract
In a device for manually guided registration for overlaying two datasets, a quality of the registration is calculated and is used to generate an answerback control signal to a three-dimensionally manipulable input device, which is used to control the registration. If the quality of the registration deteriorates, the answerback signal causes the input unit to oppose further manipulation in at least one direction which would continue or increase the deterioration of the registration. The answerback signal can brake the input unit from further manipulation in at least one manipulation direction, or can cause the input unit to attempt to return to an initial or previous position.
Claims7
A device for manually guided registration for overlaying two datasets, comprising:
- a three-dimensionally manually manipulable input device which, dependent on three-dimensional manual manipulation thereof, generates a signal for controlling registration of two datasets being overlaid, said input device having a plurality of degrees of freedom of motion respectively corresponding to a plurality of degrees of freedom of the registration;
- a registration quality calculation unit which, simultaneously with manipulation of said input unit, at least semi-automatically calculates a current quality of said registration;
- and
- an answerback unit, connected to said registration quality calculation unit and to said input device, which provides an automatic feedback signal to said input unit dependent on said current quality of said registration which causes said input unit to oppose further manipulation of said input unit in at least one of said degrees of freedom in a direction that would reduce said current quality of said registration.
