1. A method for determining an attenuation coefficient of tissue, the method comprising:
transmitting ultrasound pulses from an ultrasound transducer towards a tissue in accordance with a pulse sequence, the pulse sequence including pulses of at least one first frequency inside and at least one second frequency outside a main passband of the ultrasound transducer, wherein the pulse of at least one first frequency is within a wideband pulse range and the pulse of at least one second frequency is within a narrowband pulse range;
receiving echo signals that correspond to the pulses of the at least one first and the at least one second frequencies of the pulse sequence;
determining an attenuation coefficient of the tissue based, at least in part, on a combination of received echo signals that correspond to the pulses of the at least one first and the at least one second frequencies; and
displaying an ultrasound image concurrently with the calculated attenuation coefficient.
