Figure 1: Experimental set-up of ultrasonic A-scan GAMPT technique. (a) A thin Plexiglas plates made of acrylic and filled with water. (b) A frequency 2–5 MHz red color probe connect to the water inside Plexiglas plates without using aquasonic 100 ultrasound transmission gel between them. This probe sends sound wave through the sample (water or liquid) then receive it. (c) A control GAMPT A-scan which work as a function generator to send and receive the electrical signal then convert it to pulse sound signal wave when pass through the probe. (d) The USB wires connecting to the control GAMPT A-scan from backside and with personal computer to display the signal wave, data and result show on the personal computer monitor. (e) The overall steps together of the echoscope and its components
