The conventional way of making an acoustic image necessitates immersing the target in a fluid in the acoustic tank. The fluid is used to conduct and receive the high-frequency sound waves emitted by the transducer to the target. A shadow box-type picture frame with a piece of plastic sheeting stretched loosely and secured to the bottom of the frame can be used. The plastic sheeting, when placed on the target, will conform to that shape. When fluid is added, it will serve as a weight to insure uniform contact and also as a sound wave conductor to the target without interruption.
