Thinking of Buying...An Imaging Table
Radiolucence and tabletop motion set this equipment apart.

Pain management, orthopedics, urology and other specialties that employ minimally invasive techniques rely on intraoperative imaging to guide the way. Intraoperative imaging, in turn, requires a specialized OR table for the most effective results. Here's how to choose a table that's compatible with your C-arms and other imaging equipment.

It starts with radiolucence
The main feature distinguishing C-arm-compatible tables from conventional surgical tables is their radiolucence: that is, their composition permits the passage of X-rays for imaging purposes. In terms of a table's construction, radiolucence is achieved by way of a metal-free tabletop, frame and imaging area as well as the use of less padding.

The tabletop is made of a carbon-fiber composite material. Carbon composite products are classified by levels, which the manufacturer will be able to disclose to you. The higher the level, the less impact the table will have on radiographic imaging and the fewer artifacts will show up in your scans.

Because a table's padding can also affect the quality of a radiographic image, a C-arm table is generally upholstered with only about an inch of padding, as opposed to a surgical table's three or four inches, for greater radiolucence.

Imaging accessibility
Another aspect unique to C-arm-compatible tables is their ability to accommodate the imaging equipment and to maneuver in order to enable optimal imaging access without having to reposition the equipment or the patient.

Since a table with four legs would limit the possible placement of a C-arm, most imaging tables include a pedestal and a cantilevered tabletop for more flexibility. In addition, the tables may also slide lengthwise on the pedestal in order to increase the area along which the imaging equipment can scan.

The length of this imaging distance, or "C-arm window," varies from model to model, and the size of the imaging area needed depends on each individual specialty. Pain management procedures, for example, often require a long imaging distance of 36 inches or more, while urological or gynecological surgeries tend to use shorter fields of perhaps 24 inches. For larger surgical sites, longer imaging distances mean less necessity to image a patient piece by piece.

Positioning the patient
From a physician-user's perspective, it may be that an imaging table's positioning and adjustment features are just as useful as its tabletop's capacity for lengthwise sliding, particularly with hand- and foot-operated remote controls.

Tables with adjustable height let you raise or lower the surgical site as required for the surgeon's comfort or the procedure's performance. A table that moves from side to side allows for imaging adjustments without repositioning the patient or the equipment. A table that tilts into the Trendelenburg position is essential for pain management and orthopedic practitioners.

When considering the purchase of a table, also keep in mind the dimensions of the C-arm you're buying it for, particularly the size of the "C" that rotates around the patient. A larger C-arm can image around almost any size table, but a smaller, mini C-arm might only be able to accommodate a narrower table width. The distance between the imaging ends can have a lot of impact on the table you buy.

Weight and transport
As with most surgical tables, a standard C-arm-compatible table is rated with a weight capacity of up to 500 pounds. If you're going to be imaging bariatric patients or others over that weight, you'll most likely want to consider tables specially rated as heavy-weight, which are based on the same table platform, but with sturdier construction and a stronger motor. The heavyweight specification is important given imaging tables' cantilevered designs and their sliding and tilting capabilities, and the stress an overweight patient would place on them over an extended period.

As we've mentioned, tabletop maneuverability is fairly essential in a C-arm table. But maneuverability of the table itself may also prove useful, as a portable table means imaging can be done in any of your ORs or procedure rooms. If you're considering a table that you can transport, be sure that its motorized operations can be powered by a rechargeable battery as well as an electrical outlet.

Is refurbished the way to go?
Obviously, everyone thinks about cost when buying capital equipment. For imaging tables, cost usually depends on the options available, most notably what the table is able to do in terms of tabletop positioning and maneuverability, as well as any padding or positioning accessories for orthopedic and other specialized procedures.

Remember, though, that you're not confined to buying brand-new. In imaging tables, as with standard surgical tables, there's a big market for refurbished equipment. If you're looking to cut costs, buying a refurbished table is one option to consider.

The ideal refurbished table will come complete with a warranty. Perhaps it's only a limited warranty, but that still offers some purchase protection. Additionally, one area you'll want to examine is whether you're buying a table with the original motor. Tables are a good option for a refurbished buy because there are so few parts to rebuild — the tabletop, the base and the casters can easily be replaced — but the motor's the part that tends to expire first. And when the motor goes, you'd just as soon buy a new table. So look for a table with the motor and electronic controls rebuilt.
