Etymology of レントゲン?


What is the etymology of レントゲン (X-Ray) < From Genki II Lesson 12>?

Is it a borrowed word <外来語> from another language?

Translate suggests using X線 instead of レントゲン, but I'm not sure what the
differences are. (Is レントゲン older?)




レントゲン is named after the inventor of the X-ray, Wilhelm Röntgen (ウィルヘルム・レントゲン)
— who named them X-rays, whence the confusion.

A number of words in Japanese medical terminology were adopted from German (a
popular example being カルテ from German _Karte_ ). I guess it would not be
surprising if レントゲン was also imported already as a medical term for X-ray,
from German _Röntgenbild_ ("Röntgen image").
