摘要： A system and method of treating a patient is described, where an implantable device is introduced into the patient and guided to an appropriate location using a 2-dimentsional X ray taken prior to the introduction of the device, and a fluoroscopic image taken from the same aspect during the procedure, and using the same portion of a physiological cycle. The implantable device may be a percutaneous aortic heart valve (PHV), and the location of the device may be determined with respect to specific bodily structures identified in the 2-dimensional X-ray, such as the aortic valve and the coronary ostia. The installation position of the device is selected so as to avoid obstruction of the coronary ostia.

摘要： A method for providing measuring data for the precise local positioning of an ablation catheter comprises the recording of electrophysiological potential curves in a plurality of positions of the ablation catheter with regard to a potential measurement on a reference catheter. An x-ray image is recorded in each of the positions and the position of the ablation catheter in each instance on the x-ray image is characterized by a marker. The electrophysiological potential curves are coupled in a data-related manner with the markers. When a marker on the screen displaying the x-ray image is clicked on, the associated electrophysiological potential curves appear highlighted on another screen, if necessary in color or with increased brightness. Conversely, the x-ray image with the marker is queried, i.e. displayed and the marker highlighted when the potential curve is activated on a screen displaying the potential curve.

摘要： To make optimum use of an x-ray image recording system with an x-ray C-arm, which has an x-ray radiation source and an x-ray detector and can be pivoted about any axis, 2D axis lines are plotted in two x-ray images of an object to be imaged more precisely and these 2D axis lines are used to define a 3D axis line and the x-ray image recording system is set so that it can be directly pivoted precisely about this 3D axis line. A sequence of x-ray images is then recorded in positions of the x-ray C-arm, between which the same can be pivoted about this defined axis. This displays the object optimally.

摘要： 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.
