Feminist scholars have long argued that the pregnant body is erased – both literally and discursively – from mainstream foetal representations. Janemaree Maher argues that the placenta, as point of distinction and connection between pregnant women and foetuses, has the radical potential to refigure understandings of pregnant embodiment and subjectivity, and offer ‘a way to begin thinking through the impasse of pregnant representation’. Drawing on Maher's notion of the ‘placental body’, this article will examine the place of the placenta in (...) the practice of non-diagnostic 4D ultrasound scanning. The analysis seeks to connect Maher's theoretical perspective, and the rich feminist literature around foetal imaging, with observational data from my study of 4D scans. I will argue that the capacity of 3- and 4D sonography to image the placenta and umbilical cord in a way that is newly intelligible to lay viewers might present an opportunity for thinking differently about the interconnections – material and social – between pregnant women and foetuses and to relocate women as the subjects of their pregnancies.
