Chest x ray

I was watching Japanese hidden camera tapes and in one particular clinic a tech is telling the Japanese women to strip to the waste. The tech is not giving the ladies a gown , a mature lady is trying to take off her bra , while leaving her top on , the tech is telling her to strip to the waste , she does but tries to cover up. The video does appear to be real , I can no longer find it,. Can anybody help, I find the Japanese medical fet topics to be very extensive.

Bumping for interest.

I think the word you're looking for is "waist" rather than "waste."
