Abstract

This paper aims to describe the development of a method to monitor laser interstitial thermo therapy by MR images. The method is based on the texture analysis using fractal geometry features of the images to estimate the size of the induced necrosis. The method was validated by comparing the results to macroscopic measurements. It demonstrates the ability to achieve good estimation of the necrosis in ex-vivo experimentations involving pig liver and in vivo experimentations done on tumors grown on Copenhagen rats.
