    Abstract: An imaging system (500) includes a data acquisition system (515) configured to produce projection data and at least one memory device with reconstruction algorithms (518) and at least one blending algorithm (524). The imaging system further includes a reconstructor (516) configured to reconstruct the projection data with the reconstruction algorithms and generate at least first spectral volumetric image data corresponding to a first basis material content and second spectral volumetric image data corresponding to a second basis material content, and blend the first spectral volumetric image data and the second spectral volumetric image data with the at least one blending algorithm to produce blended volumetric image data.

    Abstract: The invention relates to a navigation system for navigating an interventional device (11) like a catheter and an interventional system comprising the navigation system. A position and shape determining unit (13) determines and stores a first position and shape of the interventional device within a living being (9) during a first interventional procedure like a first chemoembolization session and determines a second position and shape of an interventional device within the living being during a subsequent second interventional procedure like a second chemoembolization session. During the second interventional procedure the interventional device is navigated based on the stored first position and shape and based on the second position and shape. This allows considering during the second interventional procedure the path of the interventional device used during the first interventional procedure. In particular, this allows navigating the interventional device along the same path during the first and second interventional procedures.

    Abstract: The invention relates to a system and a method for guiding an intravascular ultrasound catheter device comprising an ultrasound probe to a potential lesion in a vascular tree (31). In the system, position information of the probe are provided for displaying to a user and/or for an automated processing of the position information. An evaluation unit is configured to receive a diagnostic image of the vascular tree, to determine values of at least one vessel parameter for a plurality of locations in the vascular tree, and to identify at least one location associated with an abnormal value of the at least one vessel parameter. Further, a mapping unit is configured to provide a visual indication (32) of the at least one location in the visualization of the vascular tree and/or to provide information about the at least one location for use in the automated processing of the position information.

    Abstract: The present disclosure relates to a method for controlling a magnetic resonance imaging guided radiation therapy apparatus comprising a magnetic resonance imaging system. The method comprises: acquiring magnetic resonance data using the magnetic resonance imaging system and the pulse sequence from an imaging volume; segmenting the magnetic resonance data into a plurality of segments indicating respective tissues in the imaging volume; creating a bulk electron density map of the imaging volume from the plurality of segments; displaying the bulk electron density map and radiation dose distributions for the plurality of segments on a graphical user interface, wherein the radiation dose distributions are determined using the bulk electron density map; receiving a modification signal for modifying at least a first segment of the segments; recreating the bulk electron density map using the modified first segment, and recalculating the radiation dose distribution using the bulk electron density map; redisplaying the bulk electron density map and the radiation dose distributions on the graphical user interface.
