How engineers and clinicians developed the ultrasound diagnostic scanner and how its use in obstetrics became controversial. 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."

This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.

In contemporary Western culture, the word "fetus" introduces either a political subject or a literal, medicalized entity. Neither of these frameworks does justice to the vast array of religious literature and oral traditions from cultures around the world in which the fetus emerges as a powerful symbol or metaphor. This volume presents essays that explore the depiction of the fetus in the world's major religious traditions, finding some striking commonalities as well as intriguing differences. Among the themes that emerge is the tendency to conceive of the fetus as somehow independent of the mother's body — as in the case of the Buddha, who is described as inhabiting a palace while gestating in the womb. On the other hand, the fetus can also symbolically represent profound human needs and emotions, such as the universal experience of vulnerability. The authors note how the advent of the fetal sonogram has transformed how people everywhere imagine the unborn today, giving rise to a narrow range of decidedly literal questions about personhood, gender, and disability.

In 1726, an illiterate woman from Surrey named Mary Toft announced that she had given birth to 17 rabbits. This study recreates the story of this incident and shows how it illuminates 18th-century beliefs about the power of imagination and the problems of personal identity.

This open access book deals with imaging of the abdomen and pelvis, an area that has seen considerable advances over the past several years, driven by clinical as well as technological developments. The respective chapters, written by internationally respected experts in their fields, focus on imaging diagnosis and interventional therapies in abdominal and pelvic disease; they cover all relevant imaging modalities, including magnetic resonance imaging, computed tomography, and positron emission tomography. As such, the book offers a comprehensive review of the state of the art in imaging of the abdomen and pelvis. It will be of interest to general radiologists, radiology residents, interventional radiologists, and clinicians from other specialties who want to update their knowledge in this area.

Why have cesarean sections become so commonplace in the United States? Between 1965 and 1987, the cesarean section rate in the United States rose precipitously—from 4.5 percent to 25 percent of births. By 2009, one in three births was by cesarean, a far higher number than the 5–10% rate that the World Health Organization suggests is optimal. While physicians largely avoided cesareans through the mid-twentieth century, by the early twenty-first century, cesarean section was the most commonly performed surgery in the country. Although the procedure can be lifesaving, how—and why—did it become so ubiquitous? Cesarean Section is the first book to chronicle this history. In exploring the creation of the complex social, cultural, economic, and medical factors leading to the surgery's increase, Jacqueline H. Wolf describes obstetricians' reliance on assorted medical technologies that weakened the skills they had traditionally employed to foster vaginal birth. She also reflects on an unsettling malpractice climate—prompted in part by a raft of dubious diagnoses—that helped to legitimize "defensive medicine," and a health care system that ensured cesarean birth would be more lucrative than vaginal birth. In exaggerating the risks of vaginal birth, doctors and patients alike came to view cesareans as normal and, increasingly, as essential. Sweeping change in women's lives beginning in the 1970s cemented this markedly different approach to childbirth. Wolf examines the public health effects of a high cesarean rate and explains how the language of reproductive choice has been used to discourage debate about cesareans and the risks associated with the surgery. Drawing on data from nineteenth- and early twentieth-century obstetric logs to better represent the experience of cesarean surgery for women of all classes and races, as well as interviews with obstetricians who have performed cesareans and women who have given birth by cesarean, Cesarean Section is the definitive history of the use of this surgical procedure and its effects on women's and children's health in the United States.
