Abstract: An adaptive X-ray anti-scatter device for placement in a source-detector axis of an X-ray imager includes an anti-scatter filter having a source orientable surface and a detector orientable surface. The anti-scatter filter comprises a plurality of realignable slats that absorb incident X-rays and are separated by a plurality of interstitial portions. The device also includes a first actively deformable member comprising a first set of one or more actively deformable actuators disposed across a first region of the first actively deformable member. At least a portion of the first set is partially or fully recessed within the interstitial portions. At least one actuator of the first set is in contact with a corresponding realignable slat of the plurality of realignable slats and is configured to change the alignment of the corresponding realignable slat in relation to the source-detector axis.

Abstract: Various cranial surgery OSS registration device embodiments of the present disclosure encompass a cranial surgery facial mask (128), a mask optical shape sensor (126b) having a mask registration shape extending internally within the cranial surgery facial mask (128) and/or externally traversing the cranial surgery facial mask (128), a cranial surgery tool (101), and a tool optical shape sensor (126d) having a tool registration shape extending internally within the cranial surgery tool (101) and/or externally traversing the cranial surgery tool (101). The mask registration shape of the mask optical shape sensor (126b) and the tool registration shape of the tool optical shape sensor (126d) interactively define a spatial registration of the cranial surgery facial mask (128) and the cranial surgery facial mask (128) and the cranial surgery tool (101) to a cranial image.

Abstract: The present invention relates to guidance during examinations or interventional procedures. In order to facilitate information provision in a medical environment such as an operation room or cathlab, an augmented reality display device (10) for medical equipment is provided that comprises a data input unit (12), a processing unit (20) and a display unit (22). The data input unit is configured to receive displayed operation parameters (14) of at least one medical appliance. The data input unit is also configured to receive relative location information (16) of at least one medical appliance in relation to the display unit and a viewing direction information (18) of the user. The processing unit is configured to detect if at least one of the medical appliances is in the user's field of view based on the relative location information and the viewing direction information. The processing unit is further configured to generate display data based on the operation parameters of the detected medical appliance.

Abstract: Visualization of a region of interest and planning a location of at least one injection point for a medical procedure is provided. At least one volume of imaging data for a region of interest is received. At least one virtual injection point is obtained. The at least one injection point indicates a location in a network of blood vessels for at least one injection. First and second rendering modules are controlled to construct a combined volume presentation including a first volume region rendered by a first rendering module at a relatively low level of detail and a second volume region is rendered at a higher level of detail by a second rendering module. The first and second volume regions are designated based on the at least one virtual injection point.

Abstract: An image processing system (IPS) and related method for image reconstruction operations, in particular for spectral computed tomography imaging. The image reconstruction operation is based on optimizing a regularized objective or cost function. The objective function includes a regularization term (R) that incorporates, as a-priori knowledge, a known amount of a material resident within a field of view to be reconstructed.

Abstract: A scheduler (100) which implements a method for determining a flexible schedule (205) for executing a plurality of tasks (301-308) in a system having a plurality of resources (101-103, 109-113). The schedule (205) comprises for each task (301-308) a starting time, an ending time, an assignment of resources (101-103, 109-113) to said task (301-308), as well as a collection of times and processing speeds. Using this information, the execution of a task can vary in speed when for example multiple tasks need the same resource. To do this, the scheduler first defines a partial schedule using windows (w0 , . . . , w15) and then determines the length of the windows (w0 , . . . , w15) and the processing speed of each task in each window using linear programming and column generation.
