20 MHz Transducers

Hi Everyone,
I am trying to do ultrasonic through transmission scanning of a 0.026" boron/epoxy composite patch bonded to a 0.063" aluminum plate with a 0.007" adhesive. There is a teflon tape insert in teh adhesive to simulate a debond. I am trying to get a C-scn image of this debond. I have tried with a 5 MHz unfocussed transducer and it didn't work however a 10 MHz spherical focussed transducer gave excellent results. Now i an trying with a 20 MHz spherically focussed transducer however my problem is that the A-scan is moving continuously and i an not getting any results at all. what could i do to take care of this problem. Anyones help in this matter will be highly appreciated.
