| Abstract(in English) | For realization of low-cost, faster scanning rate, and improvement of scanning resolution of puncture needle-type ultrasonography using a fused quartz rod, we developed the scanning method using the audio speaker. The principle of the scanning method is based on the movements of the end point of a lever. When the end point (transducer side) is vibrated by the audio speaker, the other point (sensing side) is also vibrated. When the endpoint of the lever is at a point during the vibration, an ultrasonic signal is transmitted and received, and the measurement of the point is conducted. We confirmed the effectiveness of the vibration scanning method by imaging the acoustic impedance difference of the muscle and fat sample. The experimental results show that the scanning method is useful for puncture needle-type ultrasonography. |
