Patent ID: 7865229

Claim:
A computer-implemented method for determining a path length from an end point of a body lumen to a site of interest in the body lumen, the method comprising the steps: obtaining location data of a wireless in vivo device; determining, using a processing unit, a raw path length value of the in vivo device between an end point of the body lumen and the site of interest, based upon the location data of the in vivo device; determining a raw total lumen length value based upon the location data of the in vivo device; calculating, using the processing unit, a relative path length value using a ratio between the raw path length value and the raw total lumen length value; calculating, using the processing unit, an actual path length between the end point of the body lumen and the site of interest, using the relative path length value and a pre-selected overall lumen length value; and displaying the actual path length value.
