摘要： A method of guiding a catheter during a treatment procedure includes acquiring scan data of a patient volume in position for the treatment procedure, registering volume data of the patient volume to the scan data, acquiring fluoroscopic data for the patient volume during the treatment procedure, and generating a volume representation of the fluoroscopic data during the treatment procedure. Generating the volume representation includes superimposing the fluoroscopic data on the volume data based on the registering. The volume representation of the fluoroscopic data is displayed, the volume representation showing a position of a mitral valve clip carried by the catheter relative to the patient volume.

摘要： A system and method of treatment of mitral valve insufficiency using an implantable medical device is described. The system uses a C-arm X-ray device configured to produce computed-tomographic (CT)-like images, and to superimpose the CT-like images on a fluoroscopic image taken with the same X-ray device as a part of the treatment procedure. The fluoroscopic images are used to guide a catheter in the patient so as to place the medical device in a proper position. The efficacy of the procedure may be assessed using a non-invasive or minimally invasive acoustic imaging technique.

摘要： A recording arrangement of an x-ray system comprises an x-ray source and an x-ray detector. Adjustment parameters can be manually supplied to the recording arrangement by an operator of the x-ray system, so that the x-ray source emits x-rays according to the manually given adjustment parameters and the x-ray detector accordingly acquires a sequence of images of an object. The manually supplied adjustment parameters can be automatically acquired by an acquisition device and stored in a remanent memory at least temporarily assigned to the acquisition device and remain stored after the completion of the acquisition of the sequence independently of a further operation of the x-ray system. The stored adjustment parameters can be retrieved from the remanent memory by the operator and supplied again to the recording arrangement so that a further sequence of images can be acquired according to the retrieved adjustment parameters.

摘要： A method for segmenting a two-dimensional angiographic recording of a vessel of a body using a computing apparatus includes providing a three-dimensional reconstruction of the vessel of the body to the computing apparatus. The two-dimensional angiographic recording of the vessel of the body is provided on the computing apparatus. The three-dimensional reconstruction of the vessel of the body is registered with the two-dimensional recording of the vessel of the body. Spatial information of the three-dimensional reconstruction is projected onto the two-dimensional recording, and the two-dimensional recording is segmented using the spatial information projected onto the two-dimensional recording.

摘要： A method for planning treatment of a stenosis in a vascular segment includes providing a geometric description of the vascular segment on a computer and determining a course of a hemodynamic parameter of the vascular segment along the vascular segment based on the geometric description provided by the computer. The computer calculates a mathematical derivative of the hemodynamic parameter over the length of the vascular segment along the vascular segment. At least one length section is specified for the vascular segment, and a value of the hemodynamic parameter in a distal end region of the vascular segment is simulated for a treatment device introduced virtually into the specified length section as a function of the mathematical derivative. The treatment of the stenosis including the introduction of the treatment device into the specified length section is planned as a function of the simulated value for the hemodynamic parameter.

摘要： A method and system for operating an x-ray device for a creation of a three-dimensional angiography of a body vessel segment. A three-dimensional reconstruction of the body vessel segment is provided to a computing device of the x-ray device. A center line of the body vessel segment is computed. An axis of rotation is laid through the center line. The three-dimensional reconstruction is registered with the x-ray device. The suitability of at least one recording angle pair with a first and a second recording angle for the creation of the three-dimensional angiography is assessed on the basis of an assessment criterion by the computing device. One of the at least one assessed recording angle pairs is selected for creation of the three-dimensional angiography as a function of a result of the assessment, in order to improve the creation of the three-dimensional angiography.

摘要： An angiographic examination method for the representation of flow properties of vessels of an object under examination is presented. To determine blood-flow parameters in 3-D with high temporal resolution, at least one 4-D DSA sequence is acquired for the generation of measurement-based 4-D DSA data sets. A model-based method determines time-dependent volume data sets, which, in terms of time, lie between the time-dependent volume data sets of the measurement-based 4-D DSA method.
