摘要： A multifunctional interface for medical imaging has a lower limb operable multifunctional interface which includes at least one activation element, such as a foot switch pedal, a timing unit, and a control unit. The activation element is configured to provide an activation signal to the control unit when being activated. Further, the timing unit is configured to provide a timing signal to the control unit upon being provided with the activation signal from the activated activation element. The control unit is configured to provide at least two different control signals for triggering at least two different predetermined actions. Further, the control signal is dependent on a duration of the timing signal.

摘要： The invention relates to an assistance device, an assistance system and an assistance method for assisting a practitioner in an interventional hemodynamic (e.g fractional flow reserve (FFR)) measurement on a subject. The FFR pressure measurements are combined with an, for example, angiography-based assessment of the coronary vessel geometry. An advanced computational fluid dynamics model may be employed to add flow and myocardial resistance data based on the interventional pressure values and on a vascular model generated prior to the intervention. In case that these data are available prior to the intervention, the location of most optimal positions for pressure measurements can be pre-calculated and by overlay of the vessel tree, for example, on the X-ray projection, advice can be given for the interventional cardiologist during the intervention.

摘要： A system and method for vascular roadmapping include an X-ray imaging device for generating a fluoroscopy image, a data base in which a plurality of contrast-enhanced images is stored, a user interface element and a processor. Each of the contrast-enhanced images is stored together with the imaging parameters based on which the image is generated. The user interface element may be configured for selecting any intended imaging parameters, such as by manually adjusting the imaging device in any position and orientation. The processor may be configured for identifying a stored contrast-enhanced image out of the plurality of contrast-enhanced images, which is generated with specific imaging parameters, where the deviation of the specific imaging parameters from the intended imaging parameters is as small as possible, thus the processor may be configured for identifying the nearest available roadmap.
