To its proponents, the ultrasound scanner is a safe, reliable,
and indispensable aid to diagnosis. Its detractors, on the other
hand, argue that its development and use are driven by the
technological enthusiasms of doctors and engineers (and the
commercial interests of manufacturers) and not by concern to
improve the clinical care of women. In some U.S. states, an
ultrasound scan is now required by legislation before a woman can
obtain an abortion, adding a new dimension to an already
controversial practice. "Imaging and Imagining the Fetus" engages
both the development of a modern medical technology and the
concerted critique of that technology.
Malcolm Nicolson and John Fleming relate the technical and
social history of ultrasound imaging--from early experiments in
Glasgow in 1956 through wide deployment in the British hospital
system by 1975 to its ubiquitous use in maternity clinics
throughout the developed world by the end of the twentieth century.
Obstetrician Ian Donald and engineer Tom Brown created ultrasound
technology in Glasgow, where their prototypes were based on the
industrial flaw detector, an instrument readily available to them
in the shipbuilding city. As a physician, Donald supported the use
of ultrasound for clinical purposes, and as a devout High Anglican
he imbued the images with moral significance. He opposed
abortion--decisions about which were increasingly guided by the
ultrasound technology he pioneered--and he occasionally used
ultrasound images to convince pregnant women not to abort the
fetuses they could now see.
"Imaging and Imagining the Fetus" explores why earlier
innovators failed where Donald and Brown succeeded. It also shows
how ultrasound developed into a "black box" technology whose users
can fully appreciate the images they produce but do not, and have
no need to, understand the technology, any more than do users of
computers. These "images of the fetus may be produced by machines,"
the authors write, "but they live vividly in the human
imagination."
