SYSTEM FOR 3D RECONSTRUCTION OF A JOINT USING ULTRASOUND

摘要

A method of generating a 3-D patient-specific musculoskeletal model. The method includes acquiring a plurality of radio frequency (RF) signals (390a) with an ultrasound probe (60) while tracking the probe (60) in 3D space, each RF signal (390a) representing a return signal (364) from a scan line of a pulse-echo ultrasound. Envelope signals (392a) are generated from each of the RF signals (390a), each envelop signal (392a) including one or more peaks (394). A contour line (456) is then generated based on the peaks (394) of the envelope signals (392). The RF signals (390a) may be generated at different frequencies, and the contour line (456) may be generated by filtering peaks (394) in temporally adjacent scan lines. A point cloud (194) may be generated from a plurality of contour lines (456).
