Abstract: A method includes x-ray image recording of a sequence of overview images of a guidewire during movement of the guidewire through an occlusion, and continuously updated determining of the position of the guidewire using an image recognition algorithm from the overview images. The method also includes continuously updated determining of the position of a tip of the guidewire using a further image recognition algorithm from the overview images, and determining a sequence of zoom images from the sequence of overview images. The zoom images, based on the position determination of the tip of the guidewire, show a cutout with the tip that is enlarged from the overview x-ray images. The method also includes automatic real-time display of at least one overview image with a displayed guidewire in each instance together with at least one zoom image with a displayed tip of the guidewire on a display unit.

Abstract: A method is provided for visualization of hollow organs of a patient. An x-ray image dataset of the hollow organ is recorded and registered. A number of individual x-ray images are recorded during a movement of an instrument with a data capture unit through the hollow organ, with each individual x-ray image featuring time information. Datasets of a data capture unit of an instrument is recorded during the movement of the instrument, with each dataset featuring time information. Position of the instrument is determined based on the individual x-ray images by an image recognition algorithm. The datasets of the data capture unit and the position of the instrument is spatially assigned based on the time information of the datasets of the data capture unit and the individual x-ray images. The datasets of the data capture unit is jointly displayed with the x-ray image dataset.

Abstract: A method for operating an x-ray image recording device having a movable x-ray detector on an-x-ray c-arm is provided. The x-ray C-arm supports an x-ray source and the x-ray detector which can be moved in the direction of the x-ray source. A variable is calculated which specifies the image quality of an x-ray image to be obtained in a position of the x-ray C-arm in a position of the x-ray detector and/or specifies the exposure dose of an operating person. A measure is taken as a function of the variable which results in a movement of the x-ray detector by the operating person and/or by an automatic movement. X-ray images are recorded in positions of the x-ray detector in which the image quality and/or the exposure dose of an operating person are optimal.

Abstract: A method is provided for a workflow for cardiovascular intervention that provides online monitoring and therapy control of the procedure. A series of steps are provided utilizing an imaging technology in combination with a therapeutic device to optimize the reliability of the treatment and minimize the negative effects on the patient. In generally, the method steps include: positioning the therapeutic device, performing the therapeutic procedure while imaging the therapeutic device, providing a low pressure inflation of the therapeutic device, imaging the results of the therapeutic procedure, and assessing the result of the therapeutic procedure. If the assessment reveals that the therapeutic procedure result is not optimal, the therapeutic procedure is performed again and the steps thereafter are performed again.
