It is not possible to provide antonyms for a proper noun like the "National Center for Health Care Technology US" as this refers to a specific government agency that serves a particular purpose. Antonyms are words that have opposite meanings to a particular word, but they cannot apply to a proper noun as it is unique and cannot have an opposite. However, some antonyms for the word "national" could be personal, regional, or local, while antonyms for "healthcare" might include sickness, illness, or disease. Technology antonyms could be old-fashioned, outdated, or obsolete.
