Abstract: The invention relates to a medical imaging system as well as a collision protection method for such a system. In this system the movement of a moveable part, e.g. a C-arm, is stopped or slowed down, if the part enters an individual protective zone enclosing the patient. This zone is calculated individually for each patient from the surface of the patient detected by an optical sensor.

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.

Abstract: The invention relates to a method for “truncation correction” in an x-ray system, i.e. a correction method during the reconstruction of projection images of an object recorded from different projection angles, if parts of the object do not lie in the field of view of each projection image. The surface of the object is thereby optically detected and used during the reconstruction of projection images to supplement the missing image data.

Abstract: Two 3D image data records are obtained mutually independently comprising healthy myocardium, myocardium having a reduced blood supply, and the necrotic myocardium. The image data records are combined to produce an overall image data record after registration, and 2D image representations are produced from the overall image data record in which the necrotic parts of the myocardium are shown emphasized, with simultaneously showing the endocardium or the healthy parts of the myocardium and parts having a reduced blood supply. The overall image data record can be used afterwards. For example, further registering step is carried out using images obtained during an intervention on the myocardium. The further registering step enables the necrotic parts of the myocardium to be assigned to the patient's situation. That can extend as far as catheters being moved automatically up to a boundary of the necrotic myocardium.

Abstract: The present invention relates to a method for determining the position of an instrument in a structure of an object with an x-ray system, in which a 3D image data record is provided for at least one area of the object relevant for determining the position, the x-ray system is registered with the 3D image data record, after the introduction of the instrument into the structure at least one 2D x-ray image of the relevant area is recorded from at least one direction of projection with a known projection geometry with the x-ray system and a 2D position of a first location of the instrument is recorded in the 2D x-ray image. In the method a projection line in accordance with the known projection geometry is placed through the 3D image data record at the 2D position and a 3D position of the first location of the instrument in the 3D image data record is determined from an intersection of the projection line with the structure. The method enables the 3D position to be determined with a simple monoplanar x-ray system.

Abstract: The present invention relates to a method to compensate for patient motion in series recordings in medical imaging, in which a plurality of images of an examination area of a patient (17) are recorded at time intervals with an imaging system (1) and related to each other. The invention also relates to an imaging system (1) for implementing the method. With the method, before the start of the series recordings a 3D image data set is recorded by a 3D recording of the examination area, which establishes a reference system. A first spatial position of the examination area in the reference system is then either obtained by recording a first image of the series recordings and registering it with the 3D image data set or by calculating it from a known calibration of the imaging system (1). Each further image of the series recordings is registered immediately after recording with the 3D image data set, to obtain the current spatial position of the examination area in the reference system. Finally a difference in respect of the first spatial position is determined and at least some of the difference is compensated for at least approximately by changing geometric relationships of the imaging system (1) in temporal proximity to registration. The method allows patient motion to be compensated for without interaction by the user of the imaging system.

Abstract: To make interventional instruments such as catheters more easily identifiable in X-ray images, the catheters are provided with marking elements which can be recognized in the X-ray image. Examples of marking elements are sphere-shaped and ring-shaped marking elements, the ring-shaped marking elements being able to identify the catheters in the manner of a barcode and so being able to make different catheters distinguishable from one another in the X-ray image.

Abstract: A method and a device for obtaining a volume data set of a mobile tissue or organ of a patient by a C-arm X-ray device are provided. An electromagnetic sensor of a position detection system is arranged indirectly on the tissue or organ. The X-ray device obtains a plurality of X-ray projections from the tissue or organ from various projection directions. A first method consists of reconstructing a volume data set from the X-ray projections, in which the electromagnetic sensor adopts a position characterizing a displacement phase of the tissue or organ. A second method consists of reconstructing a volume data set from the X-ray projections captured when the electromagnetic sensor was located in a position characterizing a displacement phase of the tissue or organ. A third method does not capture an X-ray projection for the reconstruction if the electromagnetic sensor is located in a position characterizing a displacement phase.

Abstract: With a method for supporting an interventional medical operation, a 3-dimensional image data set is recorded before the method. A positioning system is coupled with the coordinates system of the 3-dimensional image data set. The instrument is positioned and the position of the instrument in the 3-dimensional image data set is determined as an instrument image data point. Two further target image data points are determined in the target region, in which the instrument is to be guided. A plane is defined in this way. In this plane, the image data is used for a 2-dimensional display. Both the instrument image data point and also the two target image data points can be identified on the display, so that the target region of an interventional operation and an interventional medical device are displayed on an image at the same time. The image can be tracked during the interventional medical operation.
