| 摘要 |
An ultrasonic irradiation apparatus is presented which is capable of easily irradiating, with ultrasonic waves, a wide area (range) of an object having three-dimensionally curved surfaces. The apparatus includes an ultrasonic irradiator having a plurality of ultrasonic transducers arranged in planar manner, wherein the position of at least a portion of the ultrasonic transducers is arranged to be mutually and flexibly changeable in three dimensions. The ultrasonic irradiator includes a plurality of ultrasonic transducers installed on a surface of a sheet member being flexible and/or elastic or on a net member being flexible and/or elastic. The ultrasonic irradiator further includes a plurality of ultrasonic transducers composed of a flexible piezoelectric sheet member, wherein driving electrodes are arranged on one surface and opposed electrodes are arranged on another surface facing each other. The ultrasonic irradiator may be installed on a surface of a flexible planar bag containing a fluidic material serving as an ultrasonic conductive medium or arranged inside of the planar bag. The apparatus also includes means for moving or tilting the ultrasonic irradiator with respect to an object. The ultrasonic irradiator further has a band holding member for fitting the irradiator to an object. <IMAGE> |
