Ultrasonic interrogating apparatus for needle insertion has an array of ultrasonic transducers, electronics for exciting the transducers to ultrasonic emission and receiving ultrasonic echoes therefrom, a housing for the electronics having first and second ends, and a display for presenting the received echoes. The array of transducers is seucred to the electronics housing in laterally offset relationship therefrom. The passage extends through the array of transducers without extending through the electronics housing. A needle is inserted through the passage in the transducer array for the purpose of aspiration or biopsy. The passage comprises a longitudinal slot converging from end to end and a transverse slot extending laterally for the entire length of the longitudinal slot from the longitudinal slot to the side surface of the array.
