Applications of Designing Ultrasound Scanning System to Biomedical Engineering

Abstract

Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of materials, components, structures, or any systems for characteristic differences or welding defects and discontinuities without damage or destruction to the original part. NDT is also known as non-destructive examination (NDE), nondestructive inspection (NDI), and non-destructive evaluation (NDE). In this thesis, I focus on the specific type of NDT, that is ultrasonic testing. This technique is based on the propagation of ultrasonic waves in the object or material tested. This one relies on detecting the short bursts of ultrasound emitted by active cracks under a load, it also the transmission of high frequency sound into a material to interact with a feature within the material that reflects or attenuates it. In general, ultrasonic testing is based on capturing and quantifying either the reflected waves (pulse-echo) or transmitted waves (through-transmission). Each of the two types is used in certain applications, but generally, pulse-echo systems are more useful since they require one-sided access to the object being inspected. NDT has an advantage when this method does not damage the sample when it works. This method is valuable when we check the sample with high value for example, chips, wafers, air crack samples…etc…. In this study, we focus on FSAM (Fast Scan Acoustic Microscopy), this system could focus on scanning quite a small sample, but we focus on how to improve the speed of all progress.
