Bi-Plane Cath Labs vs Single-Plane Cath Labs

Bi Plane vs. Single Plane 

For those entering the cath lab market for the first time, there are scads of options on the table as you begin doing your homework and narrowing down the field. One of the major options you'll run across is whether you want a single or bi-plane cath lab system. To help you make that determination, we've compiled a short list of things you should know first.

Single and bi-plane cath labs differ from one another in several main ways:

  1. Image Acquisition Speed
  2. Specialization
  3. Space Requirements
  4. Site Preparation
  5. Cost

Image Acquisition Speed

Because bi-plane systems capture image data from detectors on two axes, they are able to acquire 3D images faster. This is especially useful in neurovascular and electrophysiology (EP) procedures. Single-plane labs are also capable of 3D imaging, but the time it takes the C-arm to move and the software’s reconstruction process cause a delay. Additionally, 3D software is not native to single-plane labs and must be added for 3D imaging to be done. 

Specialization

The type of work you plan to use your lab for will have at least as much (if not more) weight in your decision between a bi-plane and a single-plane cath lab as any other difference we'll discuss here. Bi-plane and single-plane cath labs are designed with certain specialties in mind. If your facility is planning for a dedicated neuro or EP lab, for example, you'd be best served by a bi-plane system. And if other study types come into that room on occasion, you can adjust settings to use only one of your system's C-arms.

If your work leans in a more general/blended direction (balloons, stents, angio runs, etc.) a single-plane lab can be flexible across a number of specialties and, if properly equipped with 3D software, also suffice for Neuro and EP.

Space Requirements

With a second C-arm and the cabinets of electronics required to run it, anyone would guess that a bi-plane system has a larger footprint than a single-plane system, but many don't realize how much bigger. Take for instance the GE Innova series: GE recommends a space almost 200 square feet larger for bi-plane!

If the work you're planning to do calls for bi-plane technology, don’t get scared by these dimensions. Experienced installers can do a lot to get either version of a system into more conservative spaces, but be aware that you might need more room than you think.

Cath Lab Site Preparation

I’m sure you can probably guess what this paragraph is going to say: double the c-arms = double the site prep. That might be an oversimplification, but there will be significantly more involved in getting your space ready for a bi-plane cath lab. There needs to be a ceiling support installed for the second c-arm, additional rigging is necessary, and the system has an overall larger footprint.

Any cath lab has both ceiling (monitors, maybe the gantry) and floor-mounted (table, maybe gantry) components. For a bi-plane, you have to plan for both a floor and a ceiling-mounted gantry. In the case of the Innova biplane, there’s around 2,000 lbs of additional weight hanging from the ceiling vs. its single plane counterpart, including the ceiling “Lateral Positioner” (gantry), additional rails, and additional monitors.

Cost Difference

Bi-plane cath labs simply come with more "stuff", therefore they cost more than single-plane systems. However, while there are double the critical components (tubes, collimators, detectors, computers), service pricing isn't twice as much. Currently, service coverage for a bi-plane cath lab averages 25-30% higher than service for a single-plane system.

The Takeaway 

The decision between bi-plane and single-plane is one of many you'll need to make when selecting the best cath lab for your facility's needs, but if your facility will be focusing on heart and/or brain work, the imaging advantages they offer probably make a bi-plane lab worth the extra cost and preparation.

If you have additional questions about choosing the right equipment, please don't hesitate to contact us for advice about your options.
