Wado

Wado is a term rooted in Japanese language and culture, generally associated with the idea of harmony or a harmonious path. In practice, it appears in various contexts, most prominently in martial arts and, in modern technology, in medical imaging.

The most widely known use of the term in sport is Wado-ryu karate, a major style of karate in Japan founded in the early 20th century by Hironori Otsuka. Wado-ryu blends elements of Okinawan karate with traditional Japanese jujutsu. It emphasizes smooth, flowing movements, indirect force, and the avoidance of excessive tension. The philosophy centers on harmony and balance, integrating technique, timing, and strategy to respond effectively to an opponent.

In the field of medical informatics, WADO refers to Web Access to DICOM Objects, a standard for retrieving DICOM medical images over web protocols. WADO supports access to imaging studies via HTTP using formats such as WADO-URI and WADO-RS. It is used to enable browser-based or application-based retrieval of radiology images within PACS and RIS workflows, facilitating remote viewing and integration with clinical information systems.

Beyond these uses, Wado may appear as a name or branding in various contexts that draw on the concept of harmony or the associated Japanese heritage.
