It delivers highly accurate spatio-temporal localization of instruments and automated procedural recognition, applying advanced reasoning to transform complex video sequences into structured clinical reports, regional descriptions, and rapid workflow summaries.

Together, they form a closed-loop system of visual perception, cognitive reasoning, and physical execution, advancing toward a more automated, standardized, and intelligent healthcare ecosystem.</p><p>SOURCE United Imaging Intelligence</p><p><img src="https://imageproxy.pbkrs.com/https://rt.prnewswire.com/rt.gif/query-RGF0ZUlkPTIwMjYwNDI0Jk5ld3NJdGVtSWQ9Q040Mjg5MiZUcmFuc21pc3Npb25fSWQ9MjAyNjA0MjQwOTE5UFJfTkVXU19VU1BSX19fX19DTjQyODky?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" original-src="https://imageproxy.pbkrs.com/https://rt.prnewswire.com/rt.gif/query-RGF0ZUlkPTIwMjYwNDI0Jk5ld3NJdGVtSWQ9Q040Mjg5MiZUcmFuc21pc3Npb25fSWQ9MjAyNjA0MjQwOTE5UFJfTkVXU19VU1BSX19fX19DTjQyODky"/></p></div>       </div></div>
