Fluoroskopia is an imaging technique that uses a continuous or pulsed X- ray beum to produce live, moving images of thee body Instamp; # 8217; s internal structures. Unlike conventional radiography, which coph captures a single static image, fluoroskopy displays motion in real time, allowing clinicinicians to observie thee progression of contrastt agents, guide instruments to precise location, and confirm device placement before completine a procedure.
