A method is provided for planning a position and/or a movement trajectory of a medical instrument in a heterogeneous body structure. The method includes providing at least one of a) body structure data corresponding to mechanical properties of the heterogeneous body structure, wherein said mechanical properties influence a movement of the instrument through the heterogeneous body structure due to the mechanical interaction between the instrument and the heterogeneous body structure, b) instrument data concerning mechanical and/or geometric properties of the instrument, or c) movement data concerning mechanical properties that are intended to cause and/or describe a movement of the instrument through the heterogeneous body structure. The position and/or movement trajectory-of the instrument or a probability that said position and/or movement trajectory will be achieved then is determined based on at least one of the movement data, the body structure data or the instrument data.

Planning movement trajectories of medical instruments into heterogeneous body structures

A device and method for determining at least one infusion and/or injection region for infusing and/or injecting a medical drug into a heterogeneous body structure in order to achieve a distribution of the medical drug in a desired target region of the heterogeneous body structure is provided. The device and method provide at least one property of the heterogeneous body structure that influences the spatial distribution of the medical drug in the heterogeneous body structure; and determine the at least one infusion and/or injection region from which the medical drug is to be transported through the heterogeneous body structure to the at least one target region as a function of the at least one property of the heterogeneous body structure and a position of the desired target region.

Determining an injection region in a heterogeneous body structure

A method for planning the placement of a device in a body includes analyzing information of at least part of the internal structure of the body of a patient to determine if at least one specific or critical region or structure lies within a region of interest, said region of interest within a predetermined distance of the planned trajectory of the device in the body. Then, a level of risk is assessed to the at least one specific or critical region or structure that is within the region of interest.

Risk assessment for planned trajectories

A method of adjusting infusion parameters that provide coverage of a selected target volume for direct infusions of a fluid includes using an algorithm for calculation of optimal packing of spheres or cylinders in a selected volume to determine the coverage of the selected target volume.
