Ultrasound Pt. 2, AMIRUL HAKIMI BIN JAMIL A17SC0284 - Coggle Diagram
Ultrasound Pt. 2
-
pulse-echo technique
-
the reflected wave return to scanhead and processed by u/s machine which image that represents the reflection.
Transducer
conversion of electrical pulses to mechanical vibrations. It can also be conversion of returned mechanical vibrations to electrical energy
-
piezoelectric material
-
artificial
ferroelectrics: barium titaniae, lead zirconate titanate
piezo crystal thickness
-
heating the crystal above this temperature will reduce its usefulness so crystal should not be autoclaved
Couplant
-
water soluble gel, water and disinfectant fluid.
piezoelectric element
converts electrical to mechanical which is transmit mode while the other way around is received mode.
