AI Technical Summary
Technical Problem
Existing technologies involve large computational loads and insufficient accuracy when calculating ultrasonic beam delay values, which cannot meet the requirements of beamforming.
Method used
The method adopts a monotonically increasing approach based on the difference dn of the ultrasonic beam path delay value between the (n+1)th and nth sampling points on the same scanning line. A correction step size and quantization interval are introduced, and the computational load is reduced while ensuring accuracy through iterative calculation.
Benefits of technology
By simplifying addition, subtraction, and squaring operations, resource consumption is reduced, computational efficiency is improved, cumulative errors are reduced, and the accuracy of iterative calculations is ensured.

Abstract
本申请涉及超声技术领域，提出了一种超声波束声程的确定方法及相关装置，用于解决如何减少波束合成时的计算量并保证计算精度的问题。本申请在第n采样点迭代计算得到标准延时值平方L2(n)、估计延时值paddl(n)、输出延时值p(n)、增量dn‑1和变量dl2(n‑1)后，针对第n+1采样点假设d′n＝dn‑1，得到p′addl(n+1)，并根据量化间距得到L2(n+1)。估计延时值与标准延时值由加减运算求出，因此提高了计算效率。再根据p′addl(n+1)计算M(n+1)，比较L2(n+1)与M(n+1)的大小，确定第n+1采样点的dn、paddl(n)和p(n+1)，保证计算精度。最后根据输出延时值确定采样点的超声波束声程。
