High Definition Pentax Video endoscope
Pentax High Definition video endoscope VNL-1590STi
I recently purchased the Pentax High Definition video endoscope VNL-1590STi and I thought I would compare it to my older version video endoscope, model VNL-1170K. Both are high-quality. The VNL-1170K has a resolution of 720 x 480 pixels. The VNL-1590STi is being captured at 720p with a resolution of 1280 x 720 pixels.
The papillomas are on the edge of the left vocal cord. They are recognized by the red spots in the center of each cell. She has had prior surgeries so not all of the blood vessels are normal. There is scar tissue on the right vocal cord. The differences between images are best appreciated when the images are viewed full-size.
