Abstract: The present invention relates to a method for registration of a sequence of 2D image data (5) of a hollow channel (2), in particular of a vessel, recorded with an imaging endoluminal instrument (1) when the relative displacement positions of the instrument (1) in the hollow channel (2) are known, with 3D image data (8) of the hollow channel (2). In the method a three-dimensional path of a central axis (10) of a definable section of the hollow channel (2) is determined from the 3D image data (8), the three-dimensional path of the central axis (10) is converted into a rectilinear path by a first transformation of the 3D image data (8) of the definable section of the hollow channel (2) and transformation parameters required for the first transformation are stored. A combined 3D image data record (11) is generated from the sequence of 2D image data (5) by a parallel side-by-side arrangement on a central straight line in accordance with the known relative displacement positions, and is first registered with the transformed 3D image data (9) by equating the central straight line with the rectilinear path of the central axis (10) and suitable translation for superposition of a shared reference point. The combined 3D image data record (11) or 2D image data (5) contained therein is then registered with the 3D image data (3), taking into account the stored transformation parameters.

Abstract: In a device for manually guided registration for overlaying two datasets, a quality of the registration is calculated and is used to generate an answerback control signal to a three-dimensionally manipulable input device, which is used to control the registration. If the quality of the registration deteriorates, the answerback signal causes the input unit to oppose further manipulation in at least one direction which would continue or increase the deterioration of the registration. The answerback signal can brake the input unit from further manipulation in at least one manipulation direction, or can cause the input unit to attempt to return to an initial or previous position.

Abstract: An optical coherence tomography system for the examination of human or animal tissue or of organs includes a catheter insertable into the tissue or organ, by which light is introduced into the tissue or organ and the reflection is transmitted to an evaluation unit, where the reflection and a reference light are evaluated interferometrically to determine a two-dimensional cross-sectional view of the tissue or organ under examination. The evaluation unit uses several two-dimensional cross-sectional views to derive a three-dimensional view of the tissue or organ under examination. At least one position sensor is contained on or in the tip of the catheter, and a position-determining system derives position data, which describe the current position of the position sensor in the coordinate system of the position-determining system. The position-determining system also captures position data regarding the spatial position of the cross-sectional views in the coordinate system of the position-determining system, and the evaluation system derives the three-dimensional view from the cross-sectional views and the corresponding position data.

Abstract: Blood flow turbulence or stationary blood can occur in vessels of the body, in particular following surgical interventions or minimally invasive interventional procedures, and this can lead to the formation of thrombi. A model of such vessels is obtained on the basis of a 3D image dataset, a simulation is then performed and a check carried out to determine whether turbulence or stationary blood can be demonstrated in the simulation. The model is then modified, successively where necessary, until the simulation reveals no more turbulence. Then, on the basis of the most recently modified model that results in no turbulence and no stationary blood, an aid is provided, in particular a specific aid such as e.g. a stent produced or a screen display presented.

Abstract: A method is provided for configuring medical devices such as medical devices used in a clinical trial. Based on the needs of the clinical trial, a definition of a configuration of the medical devices to be used in the clinical trial is generated and the configuration data is transformed into a profile. The profile is distributed to sites at which the clinical trial will be conducted and the profile is applied to the medical devices at the sites to configure the medical devices. The medical devices are thereby capable of producing data that is comparable as between the sites used in the clinical trial.

Abstract: A system and method for automatically registering a three dimensional (3D) pre-operative image of an anatomical structure with intra-operative electrophysiological (EP) points of a 3D electro-anatomical (EA) image map of the anatomical structure is disclosed. The pre-operative image is displayed in a first supporting view. The intra-operative EA image map is displayed in a second supporting view. An alignment of the pre-operative image with the intra-operative map is performed by identifying at least one corresponding point on each image. The view of the pre-operative image is integrated with the EA map based on the alignment.

Abstract: An operating method for a polyplanar imaging system for time-resolved imaging of an object is provided. First and second data records are recorded at a fan angle β from different angular positions by a first and second imaging planes arranged at an offset angle γ relative to each other and swiveled through an angle of at least φ=180°+β. A third data record is created by selecting projection images from the first data record beginning from a starting angle α and from the second data record so that the third data record covers an angular range of at least φ. Three-dimensional images are reconstructed based on the third data record. The starting angle α is varied for continuously creating the third data record until α has attained its final value. The contrast of projection images in the third data record or of three-dimensional images is evaluated.
