Abstract

Claims (22)

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;
