The main research question of this thesis can be formulated as follows: What are the communicative trajectories of fetal well-being assessments using expert ultrasound technology during meetings routine prenatal meetings between sonographers and pregnant women? This can be further subdivided as follows:1. What are the characteristics of sonographers' communication during the first stage/reservation meeting (first trimester) and the normality analysis meeting (second trimester) in terms of structural, interactional and thematic organization (see chapter 4 ) ?2. What communication strategies do sonographers use to reassure pregnant women during the first milestone/booking meeting (see Chapter 5)?3. How do sonographers communicate confidence to pregnant women that fetal characteristics are normal during the 20-week gestation period (see Chapter 6)?4. How do sonographers provide explanations of risk and uncertainty and answer questions raised by pregnant women during ultrasounds (see Chapter 7)? 1.4 Chapter overviews The remainder of this chapter provides an overview (background and setting) of the research area which is followed by a history of maternity care provision in the UK. The literature examines the experiences of pregnant women, advances in ultrasound technology, and the professional role of sonographers. Chapter 2 will draw on sociological notions of normality, risk, uncertainty and reassurance within biomedicine. I argue that society's emphasis on fetal development and a healthy baby has embraced the medicalization of pregnancy through technological advances. These prenatal screening processes have opened up divergent opinions regarding "quality control", authoritative...... middle of article...... and 9 include two comprehensive case studies, which are contrasted for demonstrate the strategic approach used by the sonographer to provide information on a test result, are displayed. In Chapter 9, a shorter extract of an ultrasound recorded in 3/4D video will show a pregnant woman discussing a specific subject, expressing her concerns and seeking reassurance. The case studies include nonverbal elements noted during the scan as the pregnant woman looks at 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 its future. research directions. Research questions are considered systematically to explain how sonographers provide information to reassure parents about fetal well-being, normality and abnormality..
