ULTRASOUND IMAGING DEVICE AND IMAGING METHOD THEREOF

摘要

A 3D ultrasound imaging device including an ultrasound probe assembly and echo analyzer. The ultrasound probe assembly includes a housing and an acoustic window abutted against the housing to form a sealed chamber, wherein the surface of the acoustic window contacts with the breast of the human body to be examined; an ultrasound transducer moves at a first speed back and forth within the sealed chamber and performs high-speed pre-scanning through the acoustic window to obtain initial ultrasound signals; the echo analyzer analyzes the initial ultrasound signals to determine a quality of a ultrasound image acquired by the high speed pre-scanning; and the ultrasound transducer then moves at a second speed to perform another scan to acquire new ultrasound signals. A 3D ultrasound imaging method is also disclosed.

1. An ultrasound imaging method comprising:
performing a first scanning to a target object by using an ultrasound transducer of an ultrasound probe assembly at a first speed to obtain first ultrasound signals, wherein the ultrasound probe assembly comprises an acoustic window, and at least a part of a lower surface of the acoustic window contacts with the target object; determining a quality of the first scanning according to the first ultrasound signals; scanning the target object by using the ultrasound transducer at a second speed to obtain second ultrasound signals, and acquiring a second ultrasound image of the target object according to the second ultrasound signals; and displaying the second ultrasound image.
