title: Tracking the moveable feast: sonomicrometry and gastrointestinal motility.
abstract: Ultrasonomicrometry measures distance between piezoelectric crystals based on transmission time of ultrasound bursts. It allows monitoring of coordinated motion of small and delicate tissues, including gastrointestinal sphincters. Its suitability for motility studies in small animals such as mice suggests that its use in gastrointestinal studies will increase in coming years.
