| As shown in
the left figure, ultrasonic velocity (c) of SONAGEL is about
1,450 to 1,550 (m/s) , acoustic impedance (ρc) is 1.5
to 1.6 (kg/m2/s) , which are nearly equal to the
values of the human tissues. Ultrasonic reflection wave of
SONAGEL shows low attenuation enough to gain clear ultrasound
images. |

Image comparison of thyroid
gland with use of the linear probe
(Left: without SONAGEL, Right: with SONAGEL) |
| With use of the "SONAGEL",
fine differences of the ultrasound image at the superficial region
can be created and distinct image can be gained accordingly. |
| This fact confirms that
the examined region could be focused because of the thickness of
the gel and also that the gel is homogeneous. |
