Abstract
Abstract A portable ultrasonic scanning module is disclosed which includes a fluid-tight enclosure having a window at about the front thereof and a reflective scanner at about the rear thereof and generally facing the window. A transducer is mounted in the enclosure frontwardly of the reflective scanner with the ultrasound-emitting face of the transducer generally facing the reflective scanner and being oriented with respect to the reflective scanner at a relatively acute angle such that the beam effectively "doubles-back" past itself during its excursion through the scanning module.

Apparatus for ultrasonically imaging sections of a body by transmitting ultrasonic energy into the body and determining the characteristics of the ultrasonic energy reflected therefrom, comprising: timing means for generating timing signals; energizing/receiving means alternately operative in response to timing signals; display/record means synchronized with said timing signals for displaying and/or recording image-representative signals from the energizing/receiving means; and a portable scanning module which includes: a fluid-tight enclosure having a window at about the front thereof and a reflective scanner spaced from the window and generally facing the window, the reflective surface of said scanner including a layer of sapphire material; a transducer for converting energy from said energizing/receiving means to a beam of ultrasonic energy and for converting reflected ultrasonic energy to electrical signals, said transducer being mounted in said enclosure frontwardly of said reflective scanner with the ultrasound-emitting face of said transducer generally facing said reflective scanner such that an ultrasound beam emitted by said transducer and reflected by said reflective scanner doubles back past said transducer before passing through said window; fluid means contained in said enclosure; and driving means synchronized with said timing signals for moving said scanner in periodic fashion.
