Multifrequency ultrasound systems and methods

A method, comprising:

• iteratively transmitting, by an ultrasound transducer, an ultrasound signal into a specimen at a plurality of frequencies;
• detecting backscattered ultrasound at each of the plurality of frequencies;
• generating radiofrequency (RF) data for each of the plurality of frequencies;
• transforming at least a portion of the RF data into a raw image comprising first pixels, each first pixel comprising an intensity value;
• for each first pixel of the raw image, determining an attenuation coefficient based on at least one of:
• the intensity value of the first pixel, a transmission frequency at which the intensity value was obtained, and a depth within the specimen at which the intensity value was obtained;
• generating attenuation-corrected RF data using the determined attenuation coefficients;
• transforming the attenuation-corrected RF data into an attenuation-corrected ultrasound image comprising second pixels, each second pixel comprising an attenuation-corrected intensity value determined based at least in part on the determined attenuation coefficients;
• and
• providing the attenuation-corrected image for display on a display device.

A system, comprising a processor configured to:

• receive radiofrequency (RF) data generated by an ultrasound transducer at a plurality of frequencies, the RF data associated with a specimen;
• transform the received RF data into a raw image comprising first pixels, each first pixel comprising an intensity value;
• for each first pixel of the raw image, determine an attenuation coefficient based on at least one of:
• the intensity value of the first pixel, a transmission frequency at which the intensity value was obtained, and a depth within the specimen at which the intensity value was obtained;
• generate attenuation-corrected RF data using the determined attenuation coefficients;
• transform the attenuation-corrected RF data into an attenuation-corrected ultrasound image comprising second pixels, each second pixel comprising an attenuation-corrected intensity value determined based at least in part on the determined attenuation coefficients;
• and
• provide the attenuation-corrected image for display on a display device.
