Visualization of lesions created by thermal ablation in magnetic resonance imaging (MRI) scans

摘要

PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging (MRI) visualization method of an obstacle such as a heart injury. A magnetic resonance imaging (MRI) visualization method is provided for determining the location of a thermally induced lesion in an MRI image as a function of thermal energy applied in creating the lesion. Included by deriving a spatial pattern of MRI pixel values that represents the obstruction when expected to appear in the MRI image. The MRI image is matched with the spatial pattern of pixel values. A local maximum is found in the matched MRI image, and the position of the local maximum is presented in the matched MRI image as the position of the obstacle. [Selection diagram] Fig. 3
