1. An acoustic imaging arrangement comprising:
- a longitudinal axis defining an imaging path;
a source transducer configured and arranged for producing a beam of acoustic energy, the source transducer comprising a piezoelectric polymer-based material, the source transducer disposed along the imaging path;
at least one sensor disposed along the imaging path, the sensor constructed and arranged to produce electrical signals in response to reflected acoustic energy incident thereon; and
wherein the source transducer is configured to direct the beam of acoustic energy along the imaging path so that at least a portion of the beam of acoustic energy reflected by an object, during operation, passes through the source transducer before reaching the sensor.

33. A method of imaging a target using acoustic energy, the method comprising:
-
generating acoustic energy with a source transducer comprising a piezoelectric polymer-based material; directing at least a portion of the beam of acoustic energy such that the portion of the beam of acoustic energy is incident upon the target, reflects off the target, and then passes through the source transducer; receiving the portion of the beam of acoustic energy, which has reflected off the target and passed through the source transducer, onto the at least one sensor; and producing electrical signals in response to the acoustic energy received upon the at least one sensor. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
