[Tips for taking endoscopic pictures]

Endoscope is similar to camcorder (NOT digital camera). Endoscopists make the diagnosis by endoscopic motion pictures. Sometimes, still images are used for documentation.


It is difficult to see the surface clearly due to glistening light.


By twisting the scope a little, I can get a clear image without glistening light


In the general photography, white balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light. (Reference)

White balance is also necessary in medical endoscopy to get the best color reproduction. If the white balance is not good, the overall color cast can be different using the same endoscope. See the following example below.


Two different images taken from the same endoscope.


Measuring the size is difficult. Using the endoscopy ruler, the size can be measured objectively. The white or black band is 2 mm in width.


Sometimes, just simple water irrigation make your image much different.


Before and after water irrigation.


In the long therapeutic procedure like ESD, the endoscopic view can be blurred due to fume from electocauterization. In that case, repeating air removal and infusion (air exchange) helps clear the endoscopic view.


Before air exchange


After air exchange


There are two dates in the endoscopy system. Date in the right upper corner is provided by the image maintenance system (PACS). Date in the left side is provided by the endoscopy system. The two dates must be the same. Usually the date of the PACS is automatic, and the date of the endoscopy system is manual. It is necessary to check whether the two dates are the same.


In this example, two dates in an endoscopy image are different.
