Abstract: A computer-implemented method is provided for anatomically indexing a subject. The method includes: receiving image scan data representing a volume of a subject, where the image scan data is comprised of a plurality of image slices of the subject and includes at least a portion of a vertebral column of the subject; identifying the vertebral canal of the vertebral column of the subject in the image scan data; determining a plurality of markers for the vertebral column, where each marker is indicative of a different vertebral body of the vertebral column and includes its location in the image scan data defined in a coordinate system, such that the plurality of markers define a vertebral level coordinate system; and storing each marker along with its location in a database. The markers can subsequently be used to reference other anatomical components of the subject across different image scans.

Abstract: A noninvasive, quantitative imaging technique is presented for detecting and diagnosing liver disease, such as cirrhosis. The technique includes: capturing scan data from a subject using computed tomography or another type of imaging method and extracting image data representing the liver from the scan data. Various measures of the liver may be obtained from image data and then used to compute random variables of a statistical model, where the model is predictive of a medical condition of the liver and comprised of random variables that are indicative of at least one of a shape or texture of the liver. Output from the statistical model provides an indication of an undesirable condition of the liver.
