Problems solved by technology

Despite attempts during treatment planning to determine treatment application parameters such that only the tumor receives energy, it often fails to prevent surrounding tissue from receiving a significant portion of the applied energy

Embodiment Construction

[0047] figure 1 An embodiment of a treatment system for applying treatment to a subject is shown schematically and exemplarily. The treatment system 1 includes an MRF scanner 5 for generating MRF signals of a patient 2 lying on a support mechanism 3, such as a patient table. The MRF scanner is controlled by the MRF scanner control unit 7 which provides the MRF signal to the tissue parameter distribution providing unit 10 . The tissue parameter distribution providing unit 10 is configured to determine at least one tissue parameter distribution based on the MRF signals received from the MRF scanner control unit 7 .

[0048] From, for example, D. Ma et al. in Nature, vol. 495, pp. 187-192 (2013) in the article "Magneticresonance fingerprinting" and Y. Jiang et al. in Magnetic Resonance in Medicine, pp. 1621-1631 (2015) MRFs, especially MRF sequences, are known from the articles "MR fingerprinting using fast imaging with steadystate progression (FISP) with spiral readout" in , w...

Abstract

The invention relates to a therapy planning device for planning a therapy to be applied to tissue of a subject (2). A tissue parameter distribution, which has been generated based on a magnetic resonance fingerprint scan of the tissue, and a therapy goal distribution, which defines a distribution of at least one parameter being indicative of a desired effect of the therapy, are provided. A machinelearning module (13), which has been trained to output at least one therapy application parameter defining the application of the therapy based on an input tissue parameter distribution and an inputtherapy goal distribution, is used for planning the therapy by determining the at least one therapy application parameter based on the provided tissue parameter distribution and the provided therapy goal distribution. This allows for a consideration of the actual quantitative tissue parameter distribution of the patient, thereby improving planning quality.

Description

technical field [0001] The present invention relates to a treatment planning apparatus, a treatment planning method and a computer program for planning a treatment to be applied to the tissue of a subject. The present invention also relates to a therapy system for applying therapy to a subject, said system comprising said therapy planning apparatus. Furthermore, the invention also relates to a training system, a training method and a computer program for training a machine learning module of the treatment planning device. Background technique [0002] One treatment that needs to be planned is, for example, thermal ablation therapy, in which the tumor is ablated by energy in the form of, for example, heat, cold, electricity, and in which radio frequency (RF) ablation can be used that is placed in or near the tumor device, microwave ablation device or cryogenic ablation device. In order to plan the ablation procedure, treatment application parameters can be determined, such ...
