Embodiment Construction

[0018] The present invention relates to patient-specific modeling and simulation of liver tumor ablation using medical imaging data. Embodiments of the invention are described herein to give a visual understanding of methods for patient-specific modeling and simulation using medical imaging data. Digital images usually consist of digital representations of one or more objects (or shapes). Digital representations of objects are generally described herein in terms of recognizing and manipulating objects. Such manipulations are virtual manipulations performed in the computer system's memory or other circuitry / hardware. Accordingly, it is to be understood that embodiments of the present invention may be implemented within a computer system using data stored within the computer system.

[0019] Embodiments of the present invention utilize a computing framework for patient-specific planning and guidance of radiofrequency ablation procedures. Starting from preoperative 3D medical ...

Abstract

The present invention relates to a system and method for patient specific modeling of liver tumor ablation. A method and system for tumor ablation planning and guidance based on a patient-specific model of liver tumor ablation is disclosed. A patient-specific anatomical model of the liver and circulatory system of the liver is estimated from 3D medical image data of a patient. Blood flow in the liver and the circulatory system of the liver is simulated based on the patient-specific anatomical model. Heat diffusion due to ablation is simulated based on a virtual ablation probe position and the simulated blood flow in the liver and the venous system of the liver. Cellular necrosis in the liver is simulated based on the simulated heat diffusion. A visualization of a simulated necrosis region is generated and displayed to the user for decision making and optimal therapy planning and guidance.

Description

[0001] This application claims priority to US Provisional Application No. 61 / 724,567, filed November 9, 2012, the disclosure of which is hereby incorporated by reference. Background technique [0002] The present invention relates to ablation planning, and more particularly to treatment planning and guidance based on patient-specific models for liver tumor ablation using medical imaging data. [0003] Ablation is an option for cancer treatment. Despite recent advances in cancer treatment, treatment of abdominal primary and metastatic tumors remains a formidable challenge. For example, hepatocellular carcinoma (HCC) is one of the most common malignancies (eg, >1 million cases per year) encountered worldwide. In the United States alone, 1 in 153 individuals will develop HCC, with a reported 5-year survival rate of less than 15%. [0004] For both primary liver cancer and liver metastases, liver resection (partial liver resection) is the currently preferred option for patien...
