US 2026/0029519 A1 · SPATIAL COMPOUNDED HARMONIC IMAGING FOR MEDICAL ULTRASOUND APPLICATIONS

Abstract

A portable ultrasound imaging system includes a probe and a personal computer. The personal computer is connected to the probe by way of a THUNDERBOLT I/O interface. The probe includes a transducer that alternately transmits positive and negative ultrasound pulses to a target being imaged, which is a human body. Echoes of the ultrasound pulses reflected from internal structures of the human body are sampled from the transducer, digitized into echo data, and streamed to the personal computer over the THUNDERBOLT I/O interface. In the personal computer, scanlines are generated from the echo data. Overlapping scanlines are coherently compounded and positioned together to form an ultrasound image.

Dependent claims

A method of generating an ultrasound image, the method comprising:

transmitting a first positive ultrasound pulse to a first position of a target, wherein the target is a human body;
receiving a first set of echoes of the first positive ultrasound pulse;
generating a first set of scanlines from the first set of echoes;
transmitting a first negative ultrasound pulse to a second position of the target, the first negative ultrasound pulse is an inverted version of the first positive ultrasound pulse;
receiving a second set of echoes of the first negative ultrasound pulse;
generating a second set of scanlines from the second set of echoes;
coherently compounding overlapping scanlines of the first and second sets of scanlines to generate coherently compounded scanlines;
and
forming at least the coherently compounded scanlines into an ultrasound image.
