...twelve years old, going back to the Stalin era, but still eminently operational. Lamented one U.S. official: "Here we've been using the most up-to-date methods to pick up the most sophisticated bugs, and what happens? They had what amounts to an old system of crystal sets buried in the walls...
Hold That Shot. In the simplest procedures, a pulse generator sends bursts of current to a crystal, which then produces sonic energy at frequencies ranging from one million to as high as 10 million cycles per second. The pulses pass through a transducer, a combined transmitter-receiver the size of a microphone, which may be simply moistened with water and held against a patient's skull. For a pregnant woman, the transducer is held against the abdomen, which is smeared with light...

The silent intervals give it time to pick up the echoes, which are then converted into electrical impulses and fed into an oscilloscope. More complex scanners can give the equivalent of a three-dimensional picture. On the oscilloscope screen, the ultrasound echoes make a picture that may look like Lord Cornwallis' breastworks at Yorktown. Additional circuitry can make the oscilloscope hold the picture long enough for the doctor to snap a photograph...

It is the perfect place in which to pop a champagne cork...
