Providing a patient model of a patient

A method for providing a patient model of a patient, comprising:

• receiving a first patient model of the patient via an interface, the first patient model being a multi-parametric patient model and the first patient model including a first image dataset of the patient, the first image dataset being coordinated relative to a patient coordinate system;
• receiving a second image dataset of the patient via the interface, the second image dataset being based on a medical imaging apparatus and being coordinated relative to a device coordinate system, the device coordinate system being a coordinate system relative to the medical imaging apparatus;
• determining, via at least one of a processor and processing circuitry, a transformation function to transfer the device coordinate system into the patient coordinate system;
• determining, via the at least one of the processor and processing circuitry, a transformed second image dataset based on the second image dataset and the transformation function determined;
• and
• determining, via the at least one of the processor and processing circuitry, a modified first image dataset based on the first image dataset and the transformed second image dataset, the second patient model including the modified first image dataset determined, the determining of the modified first image dataset being based on segmentation of the first image dataset and segmentation of the transformed second image dataset;
• and
• providing, via the interface, a second patient model of the patient, the second patient model being a multi-parametric patient model, and the second patient model including the transformed second image dataset.
