摘要

This paper investigates a method for conducting conventional ultrasound image scanning (C-scan) in a non-immersive manner. An ultrasound coupling device is developed to couple a focusing ultrasound transducer with a sample under test through a water droplet. The transducer is immersed in a chamber filled with water. A hole-opening at the chamber’s bottom surface and a polymer film sealing the hole allow focused ultrasound to pass and reach the sample through a water droplet. An ultrasound scanning system is constructed and used for carrying out C-scan on two different samples containing pre-fabricated internal defects. By comparing the images obtained from using both conventional water immersion method and the proposed water-droplet coupling method, we demonstrate the feasibility and capability of this new type of non-immersive ultrasound image scanning method.
