According to various embodiments, the algorithm may comprise a plurality of regions. Each region may represent a different stage of the cutting and coagulation of a tissue bite.
For example, in the first region 1478, the generator may perform an analysis of initial tissue conditions (e.g., impedance).
Also, it will be appreciated that, with some tissue cuts, the second region may be completed before all available consolidated load curves are executed.

судя по этим графикам, "область" вполне подходит
"second region may be completed"
как вариант - "процессы во второй области (на графике)...
