1. An apparatus of a computing device comprising a memory, and one or more processors coupled to the memory to:
receive, simultaneously, electrical signals based on respective reflected frequencies of a reflected ultrasonic waveform reflected from a target object as a result of a transmitted ultrasonic waveform, the reflected frequencies including N reflected frequencies, and the electrical signals including N sets of electrical signals, with each set of electrical signals corresponding to one of the reflected frequencies, the N sets of electrical signals corresponding respectively to N input images of the target object, individual input images including pixels at respective pixel locations;
compound information from the electrical signals to generate compounded electrical signals, wherein compounding includes:
determining a relationship between, on one hand, a first set of electrical signals corresponding to a first image region of the target object at a first one of the reflected frequencies, and, on another hand, a first set of electrical signals corresponding to the first image region of the target object at a second one of the reflected frequencies; and
using the relationship to predict a second set of electrical signals corresponding to a second image region of the target object at the second one of the reflected frequencies based on a second set of electrical signals corresponding to the second image region of the target object at the first one of the reflected frequencies; and
cause generation of an output image on a display based on the compounded electrical signals.
