A method for providing at least one procedure parameter includes acquiring at least one intraprocedural projection map that maps a hollow organ of an examination object with at least one medical object positioned in the hollow organ. A trained function is applied to the at least one intraprocedural projection map as input data. At least one parameter of the trained function is adjusted based on a simulation of a virtual positioning of at least one medical training object in a training hollow organ and of hemodynamics in the training hollow organ that are influenced by the at least one medical training object. The at least one procedure parameter is provided as output data of the trained function. The at least one procedure parameter includes a movement specification for the at least one medical object.

Provision of at least one procedure parameter

In accordance with a method for dose estimation for the irradiation of an object, a model with a total number of spatial elements is provided on a memory element. For each spatial element, the model specifies a material composition of the object. A neighborhood material composition is determined for a neighborhood of spatial elements depending on the model by a computing unit. A radiation dose for the neighborhood with regard to an ionizing radiation is determined with aid of a simulation depending on the neighborhood material composition. A dose distribution for the object with regard to the ionizing radiation is determined based on the radiation dose for the neighborhood.

Dose estimation for the irradiation of an object

A method for providing a collision model includes detecting an item of patient information that has an item of information on a spatial placement of an entry point of a medical object into an object undergoing examination. The item of patient information is registered with a movable medical device. The method also includes detecting an item of object information that has an item of information on a geometry and spatial position of a manipulator for moving the medical object. The manipulator includes a motion device and/or a member of technical medical personnel. A relative placement of the manipulator in relation to the object undergoing examination is determined based on the item of patient information and the item of object information. The collision model is provided for the purpose of moving the medical device based on the relative placement and the item of object information.

Method for providing a collision model and system

A computer-implemented method and system for providing a trained artificial intelligence determination algorithm for correcting x-ray image data with regard to noise effects, for example for scattered radiation correction of the x-ray image data. The determination algorithm, from input data comprising a recorded image dataset, determines a noise effect dataset describing the noise effects to be used for correction of the x-ray image dataset. A statistical physics model parameterized by model parameters is used to describe the noise effects. The model parameters are able to be determined at least in part using the determination algorithm including receiving of training datasets that include x-ray image sub datasets with assigned, known noise effect sub datasets and/or with at least one assigned, noise-free reference image sub dataset, training the determination algorithm using the training datasets, and providing the trained determination algorithm.
