Coherently compounded ultrasound image generation and associated systems, methods, and devices

A method, comprising:

• controlling, by a processor circuit, an array of acoustic elements in communication with the processor circuit to transmit ultrasound energy and receive echoes associated with the ultrasound energy;
• receiving, by the processor circuit, data corresponding to a set of subframes based on the received echoes, wherein the set of subframes comprises a first subframe and a second subframe;
• registering a first portion of the first subframe with a first portion of the second subframe;
• determining a correction for misalignment resulting from motion in the subframes before coherently combining data corresponding to the first portion of the first subframe and the data corresponding to the first portion of the second subframe;
• coherently combining, by the processor circuit, the data corresponding to the first portion of the first subframe and the data corresponding to the first portion of the second subframe, wherein the data corresponding to the first portion of the first subframe and the data corresponding to the first portion of the second subframe comprise phase information;
• generating, by the processor circuit, a first image based on the coherent combination of the first portion of the first subframe and the first portion of the second subframe
• generating a second image based on an incoherent combination of the first portion of the first subframe and the first portion of the second subframe;
• combining the first image and the second image;
• and
• outputting, by the processor circuit, the combined image to a display in communication with the processor circuit.
