1. A method for locating internal bleeding of a blood vessel, comprising: acquiring a plurality of image subvolume data sets from a plurality of ultrasound transducers; combining the plurality of image subvolume data sets to form a combined image volume; performing vessel segmentation on the combined image volume; automatically detecting one or more bifurcation candidates; acquiring spectral Doppler waveform data at each of the detected one or more bifurcation candidates; and determining whether the one or more bifurcation candidates are points of internal bleeding based on the acquired spectral Doppler waveform data.
