<unk>  (abbreviated<unk>  or sometimes VIR) is a subspecialty of<unk>  in which minimally invasive procedures are performed using image guidance.

Pictures (images) are used to direct these procedures, which are usually done with needles or other tiny instruments like small tubes called catheters. The images provide road maps that allow the<unk> st to guide these instruments through the body to the areas of interest.
