A method is provided for creating at least one map of vehicle surroundings with the aid of a control unit. It is checked based on a comparison between received measured data and stored or received map data, whether first features, for example semantic features, are present and complete. First features available in a vehicle surroundings are extracted from the received measured data if no or incomplete map data are present. It is checked whether a localization is possible within the vehicle surroundings with the aid of the first semantic features. If a localization is imprecise or not possible with the aid of the ascertained first features, second features are extracted from the received measured data. A digital map of vehicle surroundings is created based on the ascertained first features and/or the second features. Furthermore, a control unit, a computer program as well as a machine-readable memory medium are provided.

The present invention relates to a device () for fractional flow reserve determination. The device () comprises a model generator () configured to generate a three-dimensional model (3DM) of a portion of an imaged vascular vessel tree (VVT) surrounding a stenosed vessel segment (SVS), based on a partial segmentation of the imaged vascular vessel tree (VVT). Further, the device comprises an image processor () configured to calculate a blood flow (Q) through the stenosed vessel segment (SVS) based on an analysis of a time-series of X-ray images of the vascular vessel tree (VVT). Still further, the device comprises a fractional-flow-reserve determiner () configured to determine a fractional flow reserve (FFR) based on the three-dimensional model (3DM) and the calculated blood flow.

Fractional flow reserve determination

A method for a position determination of a vehicle, at least one camera and one sensor unit for a global satellite navigation system being situated on the vehicle. The method includes: acquiring at least one camera image of the environment of the vehicle with the aid of the camera, generating a transformed image as a function of the acquired camera image, with the transformed image having a virtual perspective pointing perpendicularly in the downward direction, determining a satellite position of the vehicle through a satellite-based position determination, and providing an aerial image of the environment of the vehicle as a function of the determined satellite position. A detection of a position of the transformed image in the supplied aerial image, and an ascertainment of a vehicle position as a function of the detected position of the transformed image in the supplied aerial image take place subsequently.

Estimating flow, resistance or pressure from pressure or flow measurements and angiography

A method for optimizing an X-ray imaging system during a mammographic examination. In order to provide an optimization of the X-ray imaging a breast is compressed between a support plate and a compression plate. A force-height curve is then acquired during the compression. An elasticity value of the breast is determined based on the force-height curve. A parameter of the X-ray imaging system is optimized based on the determined elasticity value.
