The purpose of this study was to demonstrate that the ultrasonic energy used to melt the tip of an absorbable polylactide Pin (SonicPin) does not have a significant effect on the chemical characterization and associated degradation properties of the material. The results indicate that the polylactide Pin after ultrasound is chemically equivalent to the SonicPin prior to ultrasound with regard t...

Ultrasonic pulse-echo methods are versatile, effective procedures for inspecting welds in steel structures. However, the ultrasonic methods conventionally used have two disadvantages: inspection must be performed manually by a skilled technician, and the signal obtained at the time of one inspection provides no “memory” to be used at the time of a later inspection. Our research involves the dev...

INTRODUCTION The use of noninvasive, acoustic methods like ultrasonometry is becoming increasingly interesting in the quantitative assessment of fracture healing. A reliable measurement technique has been described using ultrasonic transducers placed across the fracture gap. Ultrasonic image aiming is useful for accurate transducers location, on both sides of the gap. The study was designed to ...

INTRODUCTION: Ultrasonic energy surgical cutting devices are used to simultaneously cut and coagulate soft tissue and vessels. However, the extent of nerve damage that may result from their application in close proximity to a nerve is not clear. Hence, the purposes of this study were to determine the effects of ultrasonic (US) energy surgical cutting devices on sciatic nerve function when appli...

In indoor context awareness applications the location of people, devices or objects is often required. Ultrasound technology enables high resolution indoor position measurements. A disadvantage of stateof-the-art ultrasonic systems is that several base stations are required to estimate 3D position. Since fewer base stations leads to lower cost and easier setup, a novel method is presented that ...
