An ingestible device is provided that is adapted to move through the gastrointestinal tract and perform a diagnostic image of the tissue there. The diagnostic image includes diagnostic information as a function of time or as a function of distance traveled in the gastrointestinal tract. Particularly ingestible devices include radiopharmaceutical nuclear radiation, scintillation of scintillation fluids responsive to radiopharmaceutical nuclear radiation, fluorescent luminous drugs or optical fluorescence of naked gastrointestinal tract tissue, infrared of gastrointestinal tract tissue, gastrointestinal tract tissue Can be configured to perform diagnostic images of temperature differences along, impedance, ultrasound reflection, magnetic resonance, and combinations thereof. Ingestible devices can be adapted on the one hand for general screening of large populations and on the other hand for specific diagnosis of suspected pathologies. |
