| 摘要 |
<p>The present invention relates to a medical ultrasonic apparatus for efficiently transmitting PVDF ultrasonic acoustic output to the human body, configured such that a wear plate to be coated on a PVDF vibration source is formed into a matching layer using a matching material having an acoustic impedance value of a medium suitable between the PVDF vibration source and the human body, thereby enabling ultrasonic energy oscillated from the PVDF vibration source to be efficiently transmitted to the skin of the human body without being reflected.</p> |
