The present invention relates to a data processing method of determining a trajectory of a medical instrument to be inserted into a patient's body for treatment of a target region in the patient's body, the method being executed by a computer and comprising the following steps:

Method for inverse trajectory planning

A data processing method for determining an enhancing structure of interest within an anatomical body part, wherein the structure of interest exhibits an enhanced signal in an image of the anatomical body part generated by a medical imaging method using a contrast agent, said method being designed to be performed by a computer and comprising a region growing algorithm.

Determination of enhancing structures in an anatomical body part

An agent delivery catheter including a first hollow tube and a second hollow tube that protrudes from a distal opening of the first hollow tube and defines an agent delivery lumen extending along the entire length of the catheter. The distal end of the first tube is coupled to the second tube to form an annular cavity between the first tube and the second tube, the annular cavity provided for accommodating a retractable stylet shaft. An adapting member is disposed on and coupled to a proximal end of a ceramic member and for receiving a distal end of the stylet shaft.

Agent delivery catheter

The present invention relates to a data processing method for providing variation data which describe a physically-varying anatomical structure, in particular an indiscernible anatomical structure, in particular a non-enhancing tumor, comprising the steps of: providing second image data which describe a second image of a region of an anatomical body, wherein the region includes a second anatomical part which includes the physically-varying anatomical structure; providing first image data which represent a first image of the same region, wherein said same region includes a first anatomical part which does not include the physically-varying anatomical structure or which includes the physically-varying anatomical structure in a different physical state than in the second anatomical part; providing position change data which describe positional changes of corresponding image elements between the first image and the second image, on the basis of the first and second image data; and providing the variation data on the basis of the position change data.

Determination of a physically-varying anatomical structure

The present invention relates to a data processing method for determining an infusion location in an anatomical region of interest of a patient's body for infusing a medical substance, the method being executed by a computer and comprising steps of: a) acquiring permeability data comprising information about the permeability of anatomical vessels in the body; b) acquiring body vessels set data comprising information about a body vessel set, wherein the body vessel set represents a set of at least one anatomical body vessel in the patient's body and wherein the body vessel set data comprises information about the spatial structure of the at least one body vessel; c) acquiring coverage condition data comprising information about a predetermined coverage of a target region with the medical substance; d) determining, for a plurality of candidate infusion locations, candidate coverage data comprising information about a candidate coverage of a target region with the medical substance based on the permeability data, the body vessel set data and the coverage condition data; e) determining infusion location data comprising information about the infusion location based on the permeability data, the body vessel set data and the coverage condition data.

Method for optimising local drug delivery

The present invention relates to a method for processing image data comprising image information about a body region of a patient, the method being at least partly executed by an electronic data processing device and comprising the following steps: d) providing the image data; e) assigning, to elements of the image information, a predetermined probability for the image information contained in the respective element representing a predetermined tissue class, wherein the predetermined probability is provided independently of information about at least part of a body which is different from the body of the patient; f) determining, on the basis of the predetermined probability and for a subset of the image information comprising a plurality of the elements, an element-specific probability for individual elements of the subset representing an element-specific tissue class.
