An ingestible image scanning pill captures high resolution images of the GI tract as it passes through. Images communicated externally have exact location determination. Image processing software discards duplicate information and stitches images together, line scan by line scan, to replicate a complete GI tract as if it were stretched out in a straight line. A fully linear image is displayed to a medical professional as if the GI tract had been stretched in a straight line, cut open, laid flat out on a bench for viewing—all without making any incisions in a live patient.
