Abstract
An ultrasonic image of improved resolution is obtained by utilizing separate transducers respectively for transmission and reception of ultrasonic pulses employed for imaging a subject, one transducer being a conical or simulated conical transducer having a line focus along the cone axis and the other transducer being aimed along the line focus of the first transducer. An area to be imaged may be scanned by moving the transducers as a unit about the subject portion to be examined.
