Abstract
The gastrointestinal transit of magnetically marked solid pharmaceutical drug dosage forms can be monitored using biomagnetic measurement equipment. The presented study shows that using a 37-channel SQUID-magnetometer the investigation of the gastrointestinal transit of an ingested magnetically marked capsule becomes feasible with a temporal resolution in the order of milliseconds and a spatial resolution in the millimeter range.
