METHOD FOR RECONSTRUCTING HIGH QUALITY ULTRASOUND IMAGE AND ULTRASOUND IMAGING DEVICE THEREOF

Real-time restoration of high-quality 3D ultrasound images without blurring

This technology relates to a 3D ultrasound image restoration method and its ultrasound imaging device. It concerns a method of restoring high-definition ultrasound images based on 3D ultrasound echo signals focused for each pixel based on the resolution of the target cross-section.

Blurring artifacts and excessive computation that occurred during existing 3D ultrasound image restoration were problems that hindered the accuracy of diagnosis. This technology presents a new 3D ultrasound image restoration method and device to solve these problems.

Based on the 3D ultrasound echo signal obtained from the object, the transmission and reception delay time and phase value are calculated using the physical location information of the target cross section, and through this, the echo signal is phase rotated to obtain a high quality signal value. This technology effectively eliminates image distortion and blurring artifacts by omitting the digital scan conversion process, and minimizes the amount of calculation to create clear, high-contrast, high-definition 3D ultrasound images.

Key Features:

• Omit the digital scan conversion process, which is the main cause of blurring artifacts
• Directly calculate and restore the signal value corresponding to each pixel (second coordinate system) of the final image from the ultrasonic echo signal (first coordinate system)
• Calculate the precise transmission/reception delay time for each pixel, and convert this to a phase value to phase rotate the signal
• Restore the high-definition ultrasound image of the target cross-section based on the finally obtained signal values
