Title:
ULTRASONIC TOMOGRAM GENERATION METHOD, ULTRASONIC TOMOGRAM GENERATION DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/162378
Kind Code:
A1
Abstract:
Provided is a feature which improves the spatial resolution and contrast of ultrasonic tomograms compared to methods based on correlation between echo signals. Provided is an ultrasonic tomogram generation method, the method including: an estimation step SA100 for receiving an ultrasonic echo generated by M (a natural number greater than or equal to 2) ultrasonic oscillators, estimating noise in M-channel echo signals output by ultrasonic probes which output echo signals, and calculating a weighting coefficient, that emphasizes echo from a reception focus point, in accordance with a signal-to-noise ratio in the M-channel echo signals; and a generation step SA110 for generating a beamformer, representing an ultrasonic tomogram, from the M-channel echo signals by using the weighting coefficient calculated in the estimation step SA100.
