A
mini C-arm can literally run circles around a full-size C-arm,
as if the fixed model was standing still, which, of course, it
is.
Mini C-arms don't require a fixed residency in a dedicated room,
so you can easily roll them into the OR for on-the-go, on-demand
intraoperative imaging. Now, a mini C-arm can't do all the things a
fixed C-arm can do. Mini Cs are designed especially for extremity
imaging — hands, feet, ankles, wrists, knees, elbows — not to image
the torso or the thigh of a 5-foot-5, 350-pound patient. With their
smaller arcs and lower power dose, mini Cs can't accomodate or
penetrate dense anatomy. Here's what else you should you know
about portable fluoroscopes:
• Cost. Mini C-arms generally cost between $60,000 and $90,000. But
those aren't the only costs you need to consider. What accessories
will you need, and how much will they cost? Accessories could be a
laser light, a stand for an accompanying remote control or tablet,
wireless foot pedals and so on. How much will service cost? Will you
need to upgrade your network or electrical system? Do your surgeons
want a printer, USB storage, a CD burner? As with all capital purchas-
es, ask around, and get references from your sales reps to see what
other facilities think of each machine you're considering.
• Flat-panel detector or image intensifier? Most mini C-arms are
equipped with a flat-panel detector (FPD), which produces much bet-
ter images than the previous generation of products that featured
CCD cameras, known as "X-ray image intensifiers." While more
expensive than CCD, flat-panel technology produces a larger field of
vision and eliminates distortion; you retain true resolution and clarity
