Within a period of 30 years it has been possible to explain the pathogenesis of this disorder, develop reliable diagnostic methods, and find effective therapeutic measures.

Examination of the Female Pelvis,The pioneering work of Donald et al. (1958) dealt with the possibility of visualizing lower abdominal structures by ultrasound. Today all modern ultrasound instruments can demonstrate normal anatomic structures in the pelvis, a knowledge of which is fundamental to diagnosis.

Pregnancy (First Trimester),In the first trimester ultrasound is not yet generally accepted as a screening procedure, and in many countries used only where specific indications exist. One such indication is to monitor the outcome of therapy in infertile patients (see Chap. 15).

Physics and Instrumentation in Diagnostic Ultrasound,ulse which is converted into an ultrasound pulse. This pulse propagates along the line of sight of the transducer with a velocity which is characteristic of the medium. When the pulse strikes an interface some of the energy is reflected, and that portion which returns to the transducer is reconverte
