Retrieving high spatial frequency information in sonography

A method comprising:

• transmitting, by a transducer of an imaging device, acoustic pulses modulated with a carrier frequency;
• collecting, by the transducer, at least a portion of a high-frequency backscatter signal comprising radio frequency (RF) data;
• calculating, by a processing device of an imagining system, a summation of a square of a real part and a square of an imaginary part of the high-frequency backscatter signal, to generate an envelope signal comprising a first image suitable for display on a display device;
• calculating, by the processing device, a difference of the square of the real part and the square of the imaginary part of the high-frequency backscatter signal, to generate a complement signal that comprises high-frequency RF data lost during generation of the envelope signal;
• demodulating, by the processing device, the complement signal to generate a low-frequency complement image suitable for display on the display device with the envelope signal;
• adding the low-frequency complement imagine as an overlay to the first image to generate a combined image;
• and
• displaying, by the processing device, the combined image on the display device as diagnostic imaging.

A non-transitory computer-readable medium storing instructions that when executed by a processing device of an imaging system, cause the processing device to:

• transmit, by a transducer of the imaging system, acoustic pulses modulated with a carrier frequency;
• collect, by the transducer, at least a portion of a high-frequency backscatter signal comprising radio frequency (RF) data;
• calculate a summation of a square of a real part and a square of an imaginary part of the high-frequency backscatter signal, to generate an envelope signal comprising a first image suitable for display on a display device;
• calculate a difference of the square of the real part and the square of the imaginary part of the high-frequency backscatter signal, to generate a complement signal that comprises high-frequency RF data lost during generation of the envelope signal;
• demodulate the complement signal to generate a low-frequency complement image suitable for display on the display device with the envelope signal;
• add the low-frequency complement imagine as an overlay to the first image to generate a combined image;
• and
• display the combined image on the display device as diagnostic imaging.
