What does the gel do in an ultrasound?
because ultrasound sound waves have a difficult time traveling through the air, ultrasound gel is used to reduce the air between your patient and the transducer to reduce acoustic impedance and reflection to allow for a clear image to be produced.
better sound transmission,distinctive image display.
no toxic and irritant effect.
no damage and corrosion to the ultrasound probe.
sound speed 1520-1620m/s
sound impedance frequency 1.5×106-1.7×106
sound attenuation ≤ 0.05db/cm.mhz
viscosity ≥ 15pa.s
ph value 5.5-8
*method of application:
during the ultrasonic examination, squeeze the coupling gel and apply it directly on the diagnostic position. upon scanning by the ultrasonic instrument, a clear image may be acquired. after completing the examination, wipe out the remaining coupling agent with tissue paper
