Examples of digital imaging to provide information and recording

  • This is a link to a web page provided for people to see or buy the technology needed to do arthroscopy this is an awesome link to see how digital imaging being utilised in medicine, and to see just how advanced digital imaging has become. These images will be useful to look back on in the future to see advances in medicine.
