  • Patent number: 8249691
    Abstract: A method for converting digital images of an actuated breast into an accurate description of breast surface motion from a digital image-based elasto-tomography system comprises the steps of artificially placing a high density of fiducial markers on the breast surface, whereby the fiducial markers have different qualities and are placed in different proportions according to their quality; utilizing motion invariant properties of the fiducial markers to form a global motion invariant signature; tracking the markers on the actuated breast surface from image to image in each digital camera using the global motion invariant signature; and using the cameras calibration to measure the breast surface motion.

  • Publication number: 20080306353
    Abstract: A method of providing blood glucose therapy for a critically ill patient includes calculating a baseline nutrition feed requirement based on an algorithm that incorporates at least one of age, gender, and body size of the patient: determining a first blood glucose level; determining a second blood glucose level after a preselected time interval: determining a first body temperature reading: comparing the blood glucose levels: and administering either nutrition or insulin. The amount of nutrition administered to the patient is based on a first change in blood glucose level, the current body temperature reading, and a predetermined feed algorithm based on the second blood glucose level as well as the baseline nutritional feed requirement. The amount of insulin administered is based on a second change in blood glucose level, body temperature, and a predetermined insulin algorithm that incorporates at least one of the patient's body frame size, age, and gender.

  • Publication number: 20080287780
    Abstract: The invention includes a method and a system for obtaining accurate patient specific parameter identification at high resolution with a minimal amount of computation as applied to breast tissue stiffness reconstruction from a digital image-based elasto-tomography system. The method includes the steps of formulating the differential equation model describing tissue motion in terms of integrals of breast tissue displacement data that is measured using calibrated digital cameras; setting up a system of linear equations in the space varying tissue stiffness parameters; and solving by linear least squares to obtain the unique patient specific breast tissue stiffness distribution.
