Title:
GENERATING A COMPUTER MODEL USING SCAN DATA OF A PATIENT
Document Type and Number:
WIPO Patent Application WO2005010699
Kind Code:
A3
Abstract:
A method and apparatus for generating a computer model from scan data from a patient. A plurality of key frames are selected from the scanned data, hand segmenting the frames to identify specific anatomical structures (A, B, & C), and automatically generating segmented intervening frames for the regions between the key frames using an interpolation process. The automatically segmented intervening frames are merged with the hand segmented frames so as to generate a complete set of segmented frames. A first measurement of a selected feature of the complete of segmented frames are then obtained, and hand segmenting at least one additional key frame and replacing a corresponding intervening frame with the one additional key frame within the complete set of segmented frames. A set of segmented frames is re-interpolated based upon the replaced set of key frames. A second measurement of the selected feature of the re-interpolated set of segmented frame are then obtained and compared with the first measurement. If the second measurement differs from the first measurement by a statistically significant amount, the first measurement is replaced by the second measurement.
