纽约州立大学石溪分校Wei Lin教授和加拿大Alberta大学Lawrence H Le教授来访，并作了学术报告，报告题目分别是"High Performance Computing in Biomedical Device"和"Phase velocity sensitivity of ultrasonic guided modes propagating in a layered bone model: a simulation study".

Wei Lin教授报告摘要：现场可编程逻辑门阵列（FPGA）是早期用于高速硬件计算的集成电路芯片。随着图形处理器的突飞猛进的发展，它在高性能运算中的地位有所下降。然而现在的FPGA普遍集成了大量的数字处理模块，大大加强了硬件计算能力。许多便携式医用仪器由于受到物理限制，其分析计算能力有很大限制。FPGA不仅可以在一个系片上实现为医用仪器量身定制的硬件算法，而且同时可以集成控制检测电路，从而以小成本大幅提高仪器功能。本报告将介绍用FPGA设计硬件算法的基本结构以及应用实例。

Lawrence H Le教授报告摘要：This work is part of our project to extract bone parameters using axial transmission ultrasound data. In this presentation, I will systematically present the sensitivity analysis of leaky Lamb modes to the geometry and material characteristics of a layered bone model by means of semi-analytical finite-element modeling. The sensitivity test is aimed at answering a crucial question. Can ultrasonic guided waves detect changes in soft tissue thickness, cortical thickness and velocities? The study is important as it offers guidance to the parameter inversion process about the optimal selection of guided modes and regions of sensitivity for better inversion results.
