5 Claims

1. A method for generating a computer model from scan data from a patient and measuring a selected feature of the computer model, the method comprising:

(1) acquiring the scan data from the patient, wherein the scan data is acquired as a series of successive frames;

(2) selecting a plurality of key frames from the scan data frames;

(3) hand segmenting the selected key frames, whereby to identify specific anatomical structures;

(4) automatically generating segmented intervening frames for the frames between the key frames using an interpolation process;

(5) merging the automatically segmented intervening frames with the hand segmented key frames so as to generate a complete set of segmented frames;

(6) generating a computer model of the patient's anatomy from the complete set of segmented frames; and

(7) measuring a selected feature of the computer model.
