The main research question of this thesis can be formulated as follows: What are the communication trajectories of fetal well-being assessments using expert ultrasound technology during routine prenatal meetings between sonographers and pregnant women? This can further be divided as follows:1. What are the characteristics of the sonographer's communication during the first booking phase/meeting (first trimester) and the normality meeting (second trimester) in terms of structural, interactional and thematic organization (see Chapter 4)?2. What communication strategies does the sonographer use to reassure the pregnant woman during the first phase/booking meeting (see Chapter 5)?3. How are sonographers communicating reassurances about normal fetal characteristics to pregnant women during the 20-week gestation phase (see Chapter 6)?4. How do sonographers provide explanations about risk and uncertainty and answer questions asked by pregnant women during ultrasound encounters (see Chapter 7)? 1.4 Chapter overview The remainder of this chapter provides an outline (context and scene setting) of the research area which is followed by an overview of maternity care in the UK. The literature examines the experiences of pregnant women, advances in ultrasound technology, and the professional role of sonographers. Chapter 2 will build on the sociological notions of normality, risk, uncertainty and reassurance within biomedicine. I argue that the societal emphasis on fetal development and a healthy baby has embraced the medicalization of pregnancy using technological advances. These prenatal screening processes have opened up divergent opinions regarding 'quality control', authoritative...... half of paper ......nd 9 include two entire case studies, which are contrasting to demonstrate the approach strategically used by the sonographer are displayed to provide information about the results of a scan. In chapter 9, a short excerpt from a 3/4D video-recorded ultrasound meeting will show a pregnant woman raising a specific topic, thereby expressing her concerns and seeking reassurance. The case studies include nonverbal elements detected during the scan as the pregnant woman observes the image of her fetus and closely follows the sonographer's comments on the image. Chapter 10 draws conclusions and summarizes the main analytical results of this study, its limitations and future prospects. directions for research. Research questions are considered systematically to explain how sonographers provide information to reassure parents about the well-being, normality and abnormality of the fetus.
