Abstract: A method of registering two sets of medical image data taking into account scene changes can include providing a first and a second medical image data set by means of a medical device, subdividing the first and second medical image data sets into an equal number of sub-images, performing a number of individual registrations between the first and second medical image data sets with respective optimization of a similarity measure, identifying the sub-images that have a scene change, and performing a final registration between the first and the second medical image data set by masking out the identified sub-images or a masked out sub-image combination. For each individual registration, at least one sub-image of the first and/or second medical image data set can be masked out by means of a random process when determining the respective measure of similarity.

Abstract: A method for streaming content that includes loading the content on a streaming server wherein the streaming server is designed to generate models of the content and model updates. Generating the model updates is based on the models, acquired client metrics containing viewing device specific information and a client state containing information about previously transmitted model updates. Transmitting the model updates to a viewing device. Providing the content for visualization according to the model updates.

Abstract: The present technology is the field of intraoperative imaging, wherein a planning trajectory, for example a planned drilling channel, can be displayed in a 2D X-ray image. This planning trajectory can be plotted by the surgeon in a provided 3D image data set and then displayed in the 2D X-ray image by determining the position in space via a projection geometry into an arbitrary position and orientation of a C-arm X-ray apparatus during 2D imaging.

Abstract: A slotted antenna can be used for operation in multiple frequency ranges. The slotted antenna has a first electrically conducting disc which is offset from an electrically conducting base area which forms a reference potential, the disc being connected at its outside edge to the base area by at least one first electrically conducting web. The first disc includes a recess. Above the recess, a second electrically conducting disc is situated and is connected at its outside edge to the first disc by at least one second electrically conducting web. An antenna conductor leads to the second disc.
