Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Comparison of Images of the same area in the bladder in four different SPIES modalities on a tablet computer. Participants are asked to delineate the area on the image suspect for malignancy as precise as possible with a stylus on the tablet screen. Delineated area(s) is/are captured. Time to start the drawing and total time per image are captured. Hereafter, an judgement of Image quality is asked on a scale of 0 to 10, 0 being worst possible and 10 being best possible.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Karl Storz Company has recently introduced the Storz Professional Image Enhancement System. To evaluate the interpretation of cystoscopy images in different SPIES modalities a tablet program was developed. Images of 20 bladder areas were captured in 4 different SPIES modalities; white light, Clara\&Chroma, Spectra A and Spectra B. Of each bladder area, one extra image was added to the program, so that a total of 100 images were interpreted.

Every image is shown 45 seconds on the tablet screen. Participants are asked to delineate with a stylus on the tablet the precise area they suspect to be malignant and would resect or treat. After they are done they go to the next slide and the time is stopped.After each image, participants are asked to judge the quality of the image on a scale of zero to ten, with zero being the worst and ten the best.After this judgement, the next image for interpretation is presented.
