<p>An ultrasonic applicator for an ultrasonic-echo planigraphic imaging apparatus has a plurality of ultrasonic transducer elements arranged in row on a living body application surface of the ultrasonic applicator. The ultrasonic applicator comprises a puncturing cannula guiding slot along a plane included within an applicator body and extending in a longitudinal direction, ultrasonic transducer elements arranged on both sides of the slot, and a puncturing cannula guiding mechanism for guiding a puncturing cannula through the slot to a point to be examined. The puncturing cannular inserted in the living body is exactly indicated on an indicator and the location of the puncturing cannula may readily be confirmed.</p> |
