Abstract

Ultrasonic imaging apparatus comprises a portable scanning module including a liquid-filled enclosure (51) having a window (52) and a scanning reflector (70) which reflects ultrasonic energy from a transducer (80), focused by a lens (90), through the window (52), the arrangement of parts being such that the reflected ultrasonic energy doubles back past the transducer on its way to the window. The transducer is preferably of an elliptical elongate configuration and the reflective scanner and scanning window are of elongate form in the direction of scan. The window is of rigid material and is inclined with respect to the beam. In one form, the reflector is omitted, the ultrasonic energy from the transducer passing directly through the window (Fig. 6, not shown) with scanning being effected by oscillation of the transducer. The focus may be changed in embodiments using a segmented transducer (80) in conjunction with variable delays (100) and phase control circuits (120). <IMAGE>
