An imaging system includes a display device and a transducer to transmit acoustic pulses modulated with a carrier frequency and to collect at least a portion of a high-frequency backscatter signal comprising radio frequency (RF) data. A processing device is operatively coupled to the transducer probe and to the display device, and to: calculate a summation of a square of a real part and a square of an imaginary part of the backscatter signal, to generate an envelope signal including a mode-specific image suitable for display on the display device; calculate a difference of the square of the real part and the square of the imaginary part of the backscatter signal, to generate a complement signal; demodulate the complement signal to generate a low-frequency complement image suitable for display; and display the complement image on the display device to improve diagnostic imaging.
