Systems and methods for processing ultrasound data are provided. The disclosure includes using at least one computer hardware processor to perform obtaining ultrasound data generated based, at least in part, on one or more ultrasound signals from an imaged region of a subject, the ultrasound data comprising fundamental frequency ultrasound data and harmonic frequency ultrasound data, calculating shadow intensity data based at least in part on the harmonic frequency ultrasound data, generating, based at least in part on the fundamental frequency ultrasound data, an indication of bone presence in the imaged region, generating, based at least in part on the shadow intensity data, an indication of tissue presence in the imaged region, and generating an ultrasound image of the subject at least in part by combining the indication of bone presence and the indication of tissue presence.
