Abstract

A system and method are described for the purpose of performing non invasive examination of the colon using ultrasound in an ingestible capsule. A rotatable reflector is used to reflect an ultrasound beam produced by an ultrasonic source. The rotatable reflector is designed to minimize drag. The capsule includes ultrasonic transducer elements, a control circuit and an external wireless power supply and data recorder. The recorded ultrasonic data is later processed and a virtual image of the lumen is generated for diagnostic purposes.
