Example sentences with the term (it is a verb):

This feature allows the use of the flat panel for porting fields which would ordinarily exceed the flat panel limits.

Follow the directions in this manual for porting
a single exposure and for treating an individual field.

Porting an HD-270 group varies depending upon whether you used film or EPID methods.

You can also download group fields individually. Highlight each field in order and download. Follow the directions in this manual for treating an individual
field or segment and for porting a single exposure.

Port has been translated as "θύρα", port film as "ακτινογραφία θύρας", port field as "πεδίο θύρας", etc. just so that you get the general idea. But I cannot understand how to translate it as a verb. Maybe something like "θυροποίηση" (though such a word does not exist)?
