An Ultrasound Imager for Fetal Respiratory Research

  • A. J. Cousin
Part of the Acoustical Imaging book series (ACIM, volume 9)


As a result of the limited number of useful and measurable indicators available to assess fetal well-being, research efforts are being directed toward measurement of parameters such as fetal breathing movements (FBMs). These rhythmic movements of the fetal chest occur repeatedly during the second and third trimester. Presently, investigations are proceeding at both basic physiology and clinical levels to determine the efficacy of FBM for assessment of fetal condition and as a neonatal predictor.
