Impedance Matching for High Frequency Ultrasonic Needle Transducer for Epidural Space Insertion Application
碩士 === 國立陽明大學 === 生物醫學工程學系 === 104 === Energy transfer is very important to achieve the best performance of ultrasonic transducer. The internal impedance of most ultrasonic pulser / receiver is 50Ω, so we need to make the impedance of ultrasonic needle transducer to be 50Ω. Because of the production...
