Claim Text:
1. A method to detect tumorous cell tissue in a gastrointestinal tract of a subject comprising: introducing an endocapsule into the gastrointestinal tract of the subject and, from said endocapsule in the gastrointestinal tract, emitting locally defined electromagnetic radiation toward solid tissue in the gastrointestinal tract, and thereafter deactivating said electromagnetic radiation, and thereby producing a decay of inherent fluorescence intensity as a response of said cell tissue excited by said electromagnetic radiation, and detecting intensity measurement values that occur during said decay of inherent fluorescent intensity; communicating the detected intensity measurement values to a computerized processor and, in said computerized processor automatically determining a difference autocorrelation function of the decay response of the inherent fluorescent intensity from said detected intensity measurement values; in said processor, automatically calculating, from said difference autocorrelation function, fractal dimension for the cell tissue irradiated with said electromagnetic radiation; and making a value of the determined fractal dimension available as an electronic signal at an output of said computerized processor in a form allowing a classification to be made as to a degree to which said cell tissue that was irradiated with said electromagnetic radiation is tumorous.
