METHOD AND APPARATUS FOR THREE DIMENSIONAL RECONSTRUCTION OF A JOINT USING ULTRASOUND
A method of generating a 3-D patient-specific musculoskeletal model is provided. The method acquires a plurality of raw radiofrequency ("RF") signals from an ultrasound scan of a patient's bone at a plurality of locations using an ultrasound probe that comprises a transducer array. The raw RF signals are tracked in 3-D space. Each raw RF signal is transformed into an envelope comprising a plurality of peaks by applying an envelope detection algorithm to each RF signal, each peak corresponding with a tissue interface echo. A bone echo is identified from the tissue interface echoes by selecting the last peak having a normalized envelope amplitude above a preset threshold. 2-D bone contours are determined from the plurality of bone echoes and then transformed into an integrated 3-D point cloud using the tracking data. A non-patient specific 3-0 bone model is transformed to generate the 3-D patient-specific bone model.
