Abstract: 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.

Abstract: 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.

Abstract: A method is disclosed where at least one first 3D image data set is received via a first interface, the first 3D image data set including 3D images of a vascular segment of a patient at different time points. On the basis of the first 3D image data set, both a first hemodynamic parameter of the vascular segment and the spatial course of the vascular segment are then determined. This additional information enables the calculation of a digital 3D model of the stent graft on the basis of the first hemodynamic parameter of the vascular segment and on the basis of the spatial course of the vascular segment. Hence, the 3D model takes into account the first hemodynamic parameter and the spatial course so that a stent graft based on the digital 3D model is adapted individually to the anatomy of a patient via a 3D printer.

Abstract: 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.
