Ultrasonic diagnostic apparatus, learning apparatus, and image processing method

An ultrasonic diagnostic method comprising a step of:

• generating an enhanced image by inputting first data into a learned model,
• wherein the first data is obtained by a transmission/reception of an ultrasonic wave from an ultrasonic probe to an object in a first mode,
• wherein the learned model is a model trained using machine learning with second data obtained by executing the first mode and third data generated by combining a plurality of received signals obtained by executing a second mode,
• wherein the second mode is a mode that generates a harmonic image by reducing a fundamental frequency component based on multiple signals obtained by performing multiple transmission/receptions of ultrasonic waves with different waveforms,
• wherein the third data is the harmonic image generated by the second mode, and
• wherein the enhanced image is a pseudo-harmonic image corresponding to the harmonic image.

A computer-readable storage medium non-transitorily storing a program causing a processor, when executed by the processor, to:

• generate an enhanced image by inputting first data into a learned model,
• wherein the first data is obtained by a transmission/reception of an ultrasonic wave from an ultrasonic probe to an object in a first mode,
• wherein the learned model is a model trained using machine learning with second data obtained by executing the first mode and third data generated by combining in a plurality of received signals obtained by executing a second mode,
• wherein the second mode is a mode that generates a harmonic image by reducing a fundamental frequency component based on multiple signals obtained by performing multiple transmission/receptions of ultrasonic waves with different waveforms,
• wherein the third data is the harmonic image generated by the second mode, and
• wherein the enhanced image is a pseudo-harmonic image corresponding to the harmonic image.
