The distance range is defined as the longest distance the system can detect in a 10 second period of continuous measurement. Range is a measure of both the reflection properties of the tissue and the quality of the detection by the sensor. If flat papillary tumor tissue is present in the bladder, the measurement will be performed on this tissue. The range measured on bladder tumor tissue in humans is compared to the range previously measured in pigs on normal bladder tissue during in-vivo experiments to test whether human bladder tumor tissue reflects the sensor's light well enough for the system to detect it from as far away as it could detect normal bladder tissue in pigs.","At baseline visit",[14],{"measure":15,"description":16,"timeFrame":12},"Distance sensing of normal bladder tissue","ATLAS-010-110-L1A distance range measured on normal bladder tissue.
