title: Real-time diagnostic ultrasound in obstetrics.
abstract: Real-time B-scanning is a relatively inexpensive and effective diagnostic technique, applicable with some limitations to obstetrics. It produces images at high rates so that the display appears to change continuously with changes in transducer orientation or with motion of the structures imaged. It can be used in the office setting and rapidly provides information to the properly trained examiner. The ability to detect motion provides an important added dimension to ultrasound.
