Questions & Answers about haisha ga rentogen o torimasu.

Why is が used after 歯医者 instead of は?

が marks the grammatical subject of the sentence: the person who performs the action.

So in:

歯医者がレントゲンを撮ります。

the dentist is the one who takes the X-ray.

Using は would change the nuance a little. 歯医者はレントゲンを撮ります sounds more like as for the dentist, they take X-rays or the dentist will take the X-ray with the dentist as the topic. Both can be possible depending on context, but が is a very natural way to identify who is doing the action.

What does を do in this sentence?

を marks the direct object, meaning the thing directly affected by the verb.

Here:

• レントゲン = X-ray
• を = marks it as the object
• 撮ります = takes

So レントゲンを撮ります means take an X-ray.

In other words, the X-ray is the thing being taken.

Why does Japanese use 撮ります for an X-ray? Doesn't that verb mean to take a photo?
