Provided is a method for controlling a surgical navigation system. A detection unit for detecting system control inputs made by a user is associated with a surgical navigation system, the navigation system is controlled in accordance with the control inputs, and user gestures are used as said control inputs. A gesture or a initiating user gesture defines a virtual volume surrounding the initiating gestures limits, and further predetermined gestures made in the virtual volume are recognized as a control input. Also provided is a control system for a surgical navigation system. The navigation system is associated with a detection unit for detecting system control inputs made by a user, the navigation system is controlled in accordance with the control inputs, and the detection unit includes a gesture detection system for detecting user gestures.


A method of generating a virtual collision map for use in optimizing planning of a radiation treatment by a radiation beam to be delivered from an associated treatment device on a gantry to a patient target volume (PTV) within a treatment volume of an associated patient disposed on a couch operatively coupled with the associated treatment device, the method comprising:acquiring segmented data, the segmented data being representative of a characteristic of the PTV, and representative of a non-treatment volume comprising an organ at risk (OAR) of the associated patient;modeling the PTV of the segmented data as a source of simulated rays projecting outwardly relative to the PTV and having a predetermined initial value;modeling the OAR of the segmented data as having an assigned ray attenuation feature to reduce an intensity of a selected one or more of the simulated rays passing through the OAR;defining a virtual map surface surrounding the PTV and the OAR;calculating an accumulated intensity value for points on the virtual map surface having the simulated rays passing through the points, the accumulated intensity value of each point being i) the predetermined initial value for areas of the virtual map surface having simulated rays passing directly from the PTV to the virtual map surface, and ii) the predetermined initial value attenuated by the assigned ray attenuation feature of the OAR for areas of the virtual map surface having the OAR disposed between the PTV and the virtual map surface;generating an intensity distribution on the virtual map surface in accordance with the calculated accumulated intensity values; anddetermining, in accordance with the intensity distribution, the virtual collision map defining a relationship between the associated patient disposed on the couch and plural positions of the treatment device on the gantry relative to the associated patient for delivering the radiation beam to the PTV.


The invention relates to an instrument for use in computer guided surgery. The instrument includes a shaft and a reference element adapter, wherein the reference element adapter is directly couplable to the shaft and rotatable about the shaft. A selectively operable mechanical retainer provides retention of the reference element adapter to an instrument shaft adapting interface of the instrument shaft. The instrument also includes a reference element orientating mechanism arranged at an interface between the instrument shaft adapting interface and the reference element adaptor. The reference element orienting mechanism is capable of fixing at least one angular position of the reference element. The instrument also includes a grip piece interface on the instrument shaft, and a grip piece is selectively couplable to the grip piece interface.

The invention relates to a tracking reference, comprising: a reference array (1) featuring a positionally fixed arrangement of at least two tracking markers (3); and an interface (4A) for detachably coupling the reference array (1) to a base member (2), wherein the interface (4A) comprises at least one supporting surface (5) for contacting the base member (2), wherein the interface (4A) comprises magnetic means (6) which generate a force at the reference array, wherein the force (F) is directed away from the supporting surface (5).


A method for generating planning data or control data for a radiation treatment, comprising the following steps: acquiring segmented data of an object which contains a treatment volume and a non-treatment volume; modelling at least some or all of the volume or surface of the treatment volume as a source of light or rays exhibiting a predefined or constant initial intensity; modelling the non-treatment volume as comprising volumetric elements or voxels which each exhibit an individually assigned feature or attenuation or transparency value (t_(min)tt_(max)) for the light or rays which feature is assigned to the light or ray or which attenuation or transparency maintains or reduces the intensity of the light or ray as it passes through the respective volumetric element or voxel, wherein the feature or attenuation or transparency value is individually assigned to each volumetric element or voxel of the non-treatment volume; defining a map surface which surrounds the treatment volume or the object; calculating an accumulated intensity value for points or areas on the map surface, the accumulated intensity being the sum of the intensities of all the rays which exhibit the predefined or constant initial intensity and are emitted from the volume or surface of the treatment volume and reach a respective point on the map surface preferably by following a straight line, wherein if the ray passes through a non-treatment volume or voxel, the intensity of the respective ray is reduced or attenuated by a factor which is determined by the individual feature or attenuation or transparency value of the respective non-treatment volume or voxel; and generating an intensity distribution on the map surface using the calculated accumulated intensities.
