Abstract
In a human or animal organ or other region of interest, specific objects, such as liver metastases and brain lesions, serve as indicators, or biomarkers, of disease. In a three-dimensional image of the organ, the biomarkers are identified and quantified. Multiple three-dimensional images can be taken over time, in which the biomarkers can be tracked over time. Statistical segmentation techniques are used to identify the biomarker in a first image and to carry the identification over to the remaining images. Regions of normal and abnormal parameters within the 3D biomarker structure are identified. The information is used to highlight or visualize abnormal regions on the original 2D tomographic images.
