A prosthetic cardiac valve implantation arrangement is described. The prosthetic cardiac valve implantation arrangement includes a prosthesis catheter with a prosthetic cardiac valve to be implanted; and an ICE catheter for introduction into area surrounding a cardiac valve to detect a relative position and/or relative direction of orientation of the cardiac valve with respect to the ICE catheter with the aid of an ultrasound image of the cardiac valve recorded by the ICE catheter. In addition, a navigation system is for determining an absolute position and an absolute direction of orientation of the ICE catheter; and a control facility is for controlling the insertion of the prosthetic cardiac valve into the annulus of the cardiac valve on the basis of the ultrasound image recordings of the ICE catheter and positional and/or orientation-direction information from the navigation system. Also described is a method for monitoring a catheter-based prosthetic cardiac valve implantation.

An embodiment suggests a method for visualizing an image data set, in particular a medical image data set, wherein the visualized data set displays a three dimensional arrangement having at least a first object and a second object. The method includes assigning a first set of parameter to the first object; assigning a second set of parameters to the second object; dividing the medical image data set into a first sub-region and a second sub-region; and providing a visualisation of the three dimensional arrangement by a volume rendering method, in particular by a ray-casting method or a photorealistic volumetric path tracing, the first set of parameter being applied to the first sub-region for visualizing the first object and the second set of parameter being applied to the second sub-region for visualizing the second object.

A possibility is to be created of achieving the diagnosis of objects which are difficult to access. To this end, an apparatus and a method are proposed for producing a model findings object, in which image data or images of an original findings object are provided. Geometry data and one or a number of values for at least one material property are obtained from this image data. The model findings object is finally printed via a 3D printing method according to the geometry data with a material according to the value or values of the at least one material property. A physician can then diagnose the model findings object in addition to the images using palpation.

In a method for determining the ventilation of a lung of an object under examination by magnetic resonance imaging, at least two first lung-representing image data sets are acquired at different intervals of the breathing phase. The density change of the lung tissue is automatically determined from the signal difference between the image signals of the first image data sets in at least one corresponding region of the first lung-representing image data set. The lung or the thorax volume is automatically determined using at least two of the first image data sets, or using at least an additional second lung-representing image data set in a breathing phase that corresponds with the breathing phase of a first image data set. The localized, quantitative ventilation of the lung is automatically calculated depending on the density change of the lung tissue and the change of the lung or thorax volume.

A user predefines for a computer a retrieval instruction for primary data of a patient or of several patients. The computer accesses the primary data of this patient and outputs them to the user via a visual display device. The primary data comprise the primary image data recorded by way of a primary imaging modality and/or primary information derived from said primary image data. The computer automatically checks whether it is possible to access secondary data of this patient, which comprise the secondary image data recorded via a secondary imaging modality and/or secondary information derived from said secondary image data. In the affirmative case, the computer outputs a corresponding message to the user via the visual display device and/or by accessing at least a portion of the secondary data of this patient and outputting said data to the user via the visual display device.

Operating method for a computer

At least one example embodiment discloses a method for automatically selecting a display mode for an image data record is provided. In the at least one example embodiment, spatially resolved values of a parameter are determined in a first image data record of the organ to be examined, with the parameter allowing an evaluation of a functionality of the organ to be examined. Thereupon a deviation of the determined values of the parameter from a tolerance range is localized. The result of the localization is saved, and a display mode of a second image data record is selected on the basis of the result of localization, with the second image data record being a 3D image data record. The second image data record is shown in the selected display mode.
