    Abstract: An optical tracker and a surgical device. The surgical device includes a shaft defining a longitudinal axis. The shaft has a first shaft portion configured to be inserted into a patient, and a second shaft portion configured to be located outside the patient when the first shaft portion is inserted in the patient. The surgical device further includes an actuation member actuatable relative to the first shaft portion, and an operation member operable relative to the second shaft portion. The operation member is configured to actuate the actuation member when being operated. Further, the surgical device includes a tracker coupled with the operation member so that operation of the operation member causes the tracker to move relative to the shaft, such as to rotate around the longitudinal axis.

    Abstract: A method and a device for determining a respective position of one or more markers in a 3D image coordinate system are provided. A plurality of image data sets taken from a 3D volume in which an object and one or more markers are disposed. The 3D volume comprises a central volume containing at least a portion of the object and further comprises a peripheral volume adjacent to the central volume and containing the one or more markers. The image data sets have been taken from at least one of different positions and different orientations relative to the object. A first subset comprises image data sets that each includes at least one dedicated marker of the one or more markers and a second subset comprises at least one image data set that does not include the at least one dedicated marker. The method further comprises determining, from the image data sets, a position of the at least one dedicated marker in a 3D image coordinate system of a 3D reconstruction of the central volume with the object portion.

    Abstract: Determining at least one prediction image based on at least one medical image of a patient. A method includes obtaining image data including at least one medical image including representations of a plurality of bones in a first body posture, and alignment data indicative of an alignment of at least two of the bones in a second body posture. At least one prediction image including representations of the bones in the first body posture is determined based on the image data and the alignment data. The medical image(s) may be modified based on the alignment data such that poses of the representations of the bones after the modification comply with the alignment indicated by the alignment data. The at least one prediction image and/or of information derived from one or more of the prediction image(s) may be displayed. A corresponding system, computer program and carrier are also provided.

    Abstract: A method for supporting clinical personnel with multiple navigation views is provided. The method comprises; obtaining patient tracking information indicative of tracked poses of two or more patient trackers, each of the patient trackers having a fixed spatial relationship relative to one or more anatomical elements of a patient's body; obtaining instrument tracking information indicative of tracked poses of two or more medical instruments; and triggering, based on the patient tracking information and the instrument tracking information, simultaneous display of multiple navigation views, each of the navigation views being determined based on a respective set comprising (i) at least one of the medical instruments and (ii) at least one of the patient trackers, wherein the sets differ from one another in the at least one of the patient trackers. A system, a computer program and a carrier are also provided.

    Abstract: Disclosed is a method for use in surgical navigation, the method being performed by a computing system. A first pose of a first tracker is determined in exactly four degrees of freedom, DOF, and a second pose of a second tracker is determined in exactly four DOF. Based on the first pose and the second pose, a third pose of a virtual tracker may be determined in six DOF. The virtual tracker has a fixed spatial relationship relative to the anatomical object in the six DOF of the third pose. A transformation between the third pose and a fourth pose of the anatomical object in six DOF in an image coordinate system of image data of the anatomical object may be determined or obtained. The present disclosure further relates to a computing system, a surgical navigation system and a computer program product.
