METHOD OF GENERATING PLANE WAVE USING CONVEX ULTRASOUND PROBE, APPARATUS USING THE SAME, AND SYSTEM USING THE SAME

Convex ultrasound plane wave rapid generation system

This technology relates to a plane wave generation method using a convex type ultrasonic probe that can generate a plane wave, a plane wave generation device using the method, and a plane wave generation system using the method.

When generating plane waves using a convex type ultrasonic probe, the existing method had the problem of causing high computational and space complexity.

To solve this problem, this technology proposes a method to efficiently calculate the delay time for the entire transmission direction, store it in a shift register, and quickly generate the required delay time by shifting it. This technology maximizes the performance and efficiency of ultrasound diagnostic devices by reducing the number of operations and registers required to calculate delay time.

Key Features:

• Calculate the delay time for all transmission directions in advance and store it in the shift register
• When generating a plane wave in a new direction, simply shift the previously stored delay time data to secure the required delay time
• Reduce the amount of calculation by eliminating the need to repeat complex delay time calculations for each transmission direction
• Calculation speed by making cosine operation more efficient by using a look-up table when calculating delay time improve
