Help translating a medical phrase

Question

Could you please help me translate this phrase?

대향2문접선조사?

It has to do with radiation therapy. I found 접선조사 means tangential radiation, and 대향 means opposed. But, I'm not sure about the 2문 part.

Any help?

Thanks!

I am not a medical professional. I googled around until i found this article.

The screenshot of the page is for longevity of this solution.

from this post, i can concur that 대향 2문 접선조사 translates to

Opposing Portal Irradiation

The 2문 (two doors) combines with 대향 (as you suspected) to produce opposing portals.

Perhaps the article will shed more light. From my non-medical background, it is hard to tell, but my instincts tell me the translation is very good.
