Abstract: An adaptive X-ray anti-scatter device (20) for placement in the source-detector axis (22) of an X-ray imager (8) comprising:—an anti-scatter filter having a source orientable surface and a detector orientable surface, wherein the anti-scatter filter comprises a plurality of realignable slats (24) for absorbing incident X-rays, wherein the slats are separated by a plurality of interstitial portions (26); and—a first actively deformable member (26a) comprising a first set of one or more actively deformable actuators (28a, 28b) disposed across a first region of the first actively deformable member (26a), wherein one or more actively deformable actuators of the first set of one or more actively deformable actuators are configured to change the alignment of a corresponding of slat of the anti-scatter filter in relation to the source-detector axis, wherein at least a portion of each actuator of the first set of one or more actively deformable actuators is partially or fully recessed within the interstitial portions of the anti-scatter filter, and at least one actuator of the first set of one or more actively deformable actuators is in contact with at least one realignable slat of the plurality of slats, so that a deformation of the at least one actuator of the first set of one or more actively deformable actuators of the one or more actively deformable actuators causes a corresponding change to the alignment of the at least one corresponding slat from a first alignment to a second alignment relative to the source-detector axis.

Abstract: Devices, systems, and methods for evaluating a physiological condition of a vessel are disclosed. In an embodiment, a medical system is disclosed. One embodiment of the medical system comprises a medical processing unit in communication with a first pressure sensor, a second pressure sensor, and a radiographic imaging source configured to obtain radiographic images of at least one intravascular instrument positioned within a body lumen. The medical processing unit is configured to: receive the radiographic images obtained by the radiographic imaging source; detect, using the radiographic images, when the first pressure sensor is in a pre-determined orientation with respect to the second pressure sensor; and automatically initiate normalization of the first pressure sensor and the second pressure sensor in response to detecting that the first pressure sensor is in the pre-determined orientation with respect to the second pressure sensor.

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. The display unit is configured to project information (24) related to the operation parameters of the medical appliance visible for the user based on the display data if the medical appliance is in the user's field of view. The display unit is configured to display the information as visible representation overlaid to reality.

Abstract: In cardiac roadmapping, a “roadmap”, which is typically a representation of the vasculature of a patient obtained via previously acquired data from a CT scan, is overlaid on live intervention data, showing the position of an intervention device obtained using fluoroscopy. In this way, the intervention device may be tracked inside a realistic representation of the patient. The accurate registration of the fluoroscopic image to the roadmap data is an important step, otherwise the reported live position of the intervention device would not be shown at an accurate position inside the roadmap. Registration can be performed by the injection of contrast medium. In the case of cardiac roadmapping, the small vessel diameters mean that it is possible to register intervention devices directly. However, the behavior of intervention devices in larger vessels is difficult to predict, and so device-based registration is harder to achieve in such a context. By detecting the presence of a specific intervention device and a specific vascular context, an accurate registration of the intervention device to the 3D roadmap can be provided via comparison to a library of known device configurations.
