Methods and apparatus for relative perfusion and/or viability
First Claim
1. A method of evaluating tissue of an organ, said method comprising:
- accessing image data from an imaging modality acquisition system of tissue of an organ;
performing a three-dimensional segmentation on the image data to isolate a sub-portion of the image data to allow for more accurate processing;
processing the segmented image data with a statistical classification algorithm;
identifying an abnormality in the tissue of the organ using the processed data;
assigning a degree of severity to the abnormality based on the processed data; and
creating an image visually distinguishing the degree of severity of the abnormality.

Abstract
A method of evaluating tissue of an organ includes performing at least one of classification processing and clustering processing to obtain a processed dataset to visualize at least one of the imaging agent, blood, the contrast agent, and the biomedical agent distribution in the tissue, a relative regional uptake of the at least one of the imaging agent, blood, the contrast agent, and the biomedical agent in the tissue, relative regional flow of the at least one of the imaging agent, blood, the contrast agent, and the biomedical agent and the clearance or persistence of the at least one of the imaging agent, blood, the contrast agent, and the biomedical agent within the tissue and the characterization of elemental components of disease.
