{{Main|Medical imaging}}

Medical/biomedical imaging is a major segment of [[medical device]]s. This area deals with enabling clinicians to directly or indirectly "view" things not visible in plain sight (such as due to their size, and/or location). This can involve utilizing ultrasound, magnetism, UV, radiology, and other means.

Alternatively, navigation-guided equipment utilizes [[electromagnetic]] tracking technology, such as [[catheter]] placement into the brain or [[feeding tube]] placement systems. For example, ENvizion Medical's ENvue, an electromagnetic navigation system for enteral feeding tube placement. The system uses an external field generator and several EM passive sensors enabling scaling of the display to the patient's body contour, and a real-time view of the feeding tube tip location and direction, which helps the medical staff ensure the correct placement in the [[Gastrointestinal tract|GI tract]].<ref>{{cite journal |last1=Jacobson |first1=Lewis E. |last2=Olayan |first2=May |last3=Williams |first3=Jamie M. |last4=Schultz |first4=Jacqueline F. |last5=Wise |first5=Hannah M. |last6=Singh |first6=Amandeep |last7=Saxe |first7=Jonathan M. |last8=Benjamin |first8=Richard |last9=Emery |first9=Marie |last10=Vilem |first10=Hilary |last11=Kirby |first11=Donald F. |title=Feasibility and safety of a novel electromagnetic device for small-bore feeding tube placement |journal=Trauma Surgery & Acute Care Open |date=1 November 2019 |volume=4 |issue=1 |pages=e000330 |doi=10.1136/tsaco-2019-000330 |pmid=31799414 |pmc=6861064 |url=https://tsaco.bmj.com/content/4/1/e000330 |language=en |issn=2397-5776 |access-date=3 March 2023 |archive-date=3 March 2023 |archive-url=https://web.archive.org/web/20230303053759/https://tsaco.bmj.com/content/4/1/e000330 |url-status=live }}</ref>
