Title:
ULTRASONIC IMAGING METHOD, SYSTEM, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/202362
Kind Code:
A1
Abstract:
An ultrasonic imaging method, system, and device. The method comprises: S501. pre-configuring an imaging area, then pre-configuring multiple focusing points for receiving an ultrasonic wave and a delay time for an emitter array element corresponding to the focusing point, wherein the focusing point is disposed below of the imaging area; S502. activating, according to the delay time corresponding to the focusing point, an emitter array element of the ultrasonic probe, and emitting, by means of a focusing method, and using an aperture with a diameter 30-100% of the width of the probe, an ultrasonic wave towards the focusing point; S503. determining an overlapping portion of an imaging area sampling point and an effective emitter sound field; S504. calculating a scattering intensity of the imaging area sampling point containing the effective emitter sound field to obtain a reconstructed secondary image corresponding to the focusing point; and S505. overlapping, according to a pixel position, the reconstructed secondary image obtained after a plurality of emissions to generate an image. The method improves an image frame rate and provides an ultrasonic image with a minimum of two ultrasonic wave emissions. The method also reduces a speckle size by overlapping secondary images reconstructed using different focusing points, thereby improving image resolution.
