A method and a system for determining properties of a vessel in a medical image are provided. The method involves displaying the medical image including the vessel. The displayed vessel is segmented and indicated in the medical image. For an indicated vessel, a maximum curvature along a length of the vessel is determined as the property of the vessel. Another vessel parameter which can be determined is the smallest diameter along the length of the vessel.

A method and a system for indicating a feeding vessel of a malformation in a medical image are provided. The method first displays the medical image of the malformation and its surrounding vessels. This enables a manual selects a portion of the displayed medical image with reference to the tumor. The feeding vessel of the tumor is segmented and finally indicated in the medical image based on said manual selection.

In a method and system for planning and implementing a selective internal radiation therapy (SIRT), the liver volume and the tumor volume are automatically calculated in a processor by analysis of items segmented from images obtained from the patient using one or more imaging modalities, with the administration of a contrast agent. The volume of therapeutic agent that is necessary to treat the tumor is automatically calculated from the liver volume, the tumor volume, and the body surface area of the patient and the lung shunt percentage for the patient. The therapeutic agent can be administered via respective feeder vessels in respectively different amounts that correspond to the percentage of blood supply to the tumor from the respective feeder vessels, this distribution also being automatically calculated by analysis of one or more parenchymal blood volume (PBV) images.
