Abstract: In a method for mathematical compensation of a periodic movement of an organ in a first image-generation method used to image said organ, two time series of three-dimensional image data are acquired using gating, one by the first image-generation method and one by the second image-generation method, the image data that have been acquired by the second image-generation method being used to calculate motion fields which are applied for the compensation of the data from the time series which was acquired by the first image-generation method. The compensation encompasses the mathematical inclusion of motion fields and the mapping of the image data to a reference time. All the image data mapped back to the reference time are added together.

Abstract: An x-ray device for recording projection images of a patient features a C-arm on the ends of which an x-ray source and an x-ray detector are accommodated. The x-ray detector is accommodated on the C-arm so that translation movements can be executed with the x-ray detector in relation to the C-arm. This allows the angulation area or the area of the x-ray device with which an image can be recorded to be increased.

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: The present invention relates to a method for the registration and superimposition of image data when taking serial radiographs in medical imaging, wherein a plurality of image data sets for a region of a patient (17) that is being investigated are constructed at time intervals using an imaging system (1) and are referenced with a first image data set for the region that is being investigated that was constructed previously using said imaging system (1). In the above method, a location system (2) is used during the production of serial radiographs constantly, or at least at a respective proximity in time to the construction of individual data sets, to determine a current spatial position of the region being investigated in a reference system that is firmly connected to the imaging system (1), whereby in the construction of the first image data set, a first spatial position of the region that is being investigated is recorded. In the construction of some or all further image data sets, the respective current spatial position of the region that is being investigated is determined and an image content of each first image data set is geometrically adapted on the basis of the difference between the first and the current spatial position, such that compensation is made for a different spatial position of the region that is being investigated. The geometrically adapted first image data set or an image data set derived therefrom, or an image data set that is positionally connected thereto by registration is then displayed superimposed with the respective further image data set.

Abstract: The present invention relates to a method for imaging using an image-generating, endoluminal instrument (1) by means of which a sequence of 2D image data of a hollow channel (2), in particular a vessel, of an object under investigation is recorded, wherein the images are recorded in a known temporal relation to a periodic movement of the object under investigation and spatial coordinates of the image are captured by means of a position sensor during each recording of an image (5) and stored as position data (9, 10) together with the 2D image data of the image (5). The method is characterized in that first position data (10) which does not lie in a predefinable movement phase of the object under investigation is corrected, before or after being stored, by interpolation between second position data (9) which does lie in the specified movement phase and/or by subtraction or addition of predetermined values. By means of the method a movement correction of the data can be performed without the need to reduce the volume of recorded image material.

Abstract: The device according to the invention ensures accurate and in particular sensitive navigation of the probe, which can be inserted into a body, despite the fact that the remote control uses simple means, by means of a movement (MR;MB;MP) corresponding intuitively to the navigation of a probe using the control device (1). Intuitive operation can be converted in particular using an inventive U-shaped embodiment of the control device (1). Sensitive controllability can be increased by transmitting the mechanical interaction between the probe and an environment under examination to the control device (1) and thus directly to the operating hand (3) by means of inventive feedback.

Abstract: The present invention relates to a method and also an imaging system to compensate for patient motion when recording a series of images in medical imaging, in which a number of images of an area under examination of a patient (17) are recorded at intervals with an imaging system (1) and are related to one another. With the method a localization system (2) is used as the series of images are being recorded to permanently or at a time close to the recording of the individual images, record a momentary spatial location of the area under examination in a reference system permanently linked to the imaging system (1), a first spatial location of the area under examination recorded close to the time of recording of a first image is stored, and a deviation of the images recorded momentarily in each case of the first spatial location is determined and by changing the geometrical circumstances of the imaging system (1) at a time to close the recording of the spatial location and/or through geometrical adaptation of an image content of an image just recorded, is at least approximately commentated for, so that the images show the area under examination in the same position and orientation. The method does not require any time-consuming interaction with the operator and is also suitable for compensating for larger movements of the patient.
