<p>NYIT-1814/16 The disclosed invention is an apparatus for ultrasonically investigating a section or slice of a body by transmitting ultrasonic energy into the body and determining the characteristics of the ultrasonic energy reflected therefrom. The invention is preferably practiced as an equipment which includes a console and a portable scanning module. The console houses electronics and a display, and the portable scanning module is suitable for being hand held and comprises a fluid-tight fluid-containing enclosure having a window that is placed in contact with the body being examined. The scanning module houses, among other things, the transducer, focusing means, an energizer/receiver coupled to the transducer, and a reflector for effecting a mechanical scan of the beam through the scanning window. The transducer is of an elliptical elongated configuration, and the reflective scanner and scanning window are elongated in the direction of scan. The scanning window is of a relatively rigid material and is inclined with respect to the beam. A further feature of the portable scanning module is that the reflective scanner is located at about the rear of the portable scanning module and substantially faces the window thereof. The transducer is mounted in the module frontwardly of the reflective scanner with an ultrasoundemitting face of the transducer facing the reflective scanner such that the ultrasound beam emitted by the transducer and reflected by the reflective scanner doubles back past the transducer before passing through the window.</p> |
