LINEAR-ARRAY PROBE USING BICONCAVE TRANSDUCERS

Recently, ultrasonic transducers with high resolution have been requir ed iii the field of ultrasonic diagnosis. The biconcave transducer tre ated iii this paper will be suitable for this purpose, because this tr ansducer has the features of focusing and damping effects, in the case of the radiation of ultrasonic pulse waves. These features are expect ed to lead to high lateral and time resolutions for the detection of a small object. We try to fabricate a probe of the linear array type us ing the biconcave transducers for ultrasonic diagnostic equipment, the n some of its characteristics are investigated to determine whether th is probe is suitable for the detection of a small object by the pulse echo method.
