The main problem with the contact endoscopy is their reliability and difficulties in diagnostic interpretation with standard PAL-video signal which is commonly used in standard.
For better interpretation and evaluation it's needed to capture high-resolution images (5-8 Megapixels) and analyze it using image processing and analysis methods. In our researches biopsy remains the "gold standard" to which the results from contact endoscopy are compared.
We implemented the prototype imaging system. The image detector of the system is the C-7070 Wide Zoom Olympus camera (7 Megapixels) equipped with specially constructed converter connected with Karl Storz 8715 BA contact endoscope with Storz Xenon 300 light (see Figure 1).
The computerized photographic capture system is needed because during the surgery investigation there is no possibility to make photo (surgeon's hands are busy). For this reason we decided to use InPhoto Oly software to control and capture images received during contact endoscopy.
Our investigations are financed by the Polish Committee for Scientific Research within a grant No 3 T11E 01128, what is gratefully acknowledged.
