GE Innova Cath Labs vs. GE IGS 5 Series Cath Labs

More and more, people looking for cath/angio systems ask us about GE's IGS 5 equipment series. They are the latest generation in GE's cath/angio product line, introduced in 2012, and are only just starting to creep onto the secondary market. In light of this gradual emergence, availability of used IGS 520,530, and 540 labs is still quite limited- but that doesn't mean facilities need to wait several more years to get cath lab technology that delivers high-level performance.

GE's previous generation of cath lab equipment, the Innova series, is widely available and shares so many features and components with the IGS 5 that the quality and user experience of choosing either are highly similar. Below, we'll lay out some of the similarities and differences between GE Innova and GE IGS 5 cath/angio labs.

What’s the same?

Major hardware components: Both series use the Jedi generator and the Performix 160A X-ray tube. They also use the same positioner stand. Until the fourth quarter of 2015, they came with the same digital detectors too.

Omega IV and V table options: Innova and IGS labs can both be found with the basic Omega IV and the longer Omega V table options.

RTAC 8 Computer: Until late 2015, both series used the RTAC 8 to control the image acquisition process.

InnovaCentral touchscreen table-side control: Most of the functions of models from either series can be manipulated at the side of the table from this controller; system configuration, movements, fluoroscopy modes, zoom, etc.

What’s different?

Additional table options:

In addition to the Omega IV and V table types offered with the Innova series, the IGS series adds the Innova IQ V3 and V4 for more tilt and lateral movement choices.

The original tilting table option for the Innova series is the Elegance table. Additionally, starting in late 2009, Innova systems had the option of being outfitted with Innova IQ or IQ 2 tables.

DL8-2 computer: The IGS started with the same DL8 computer as the Innova, but soon switched to the DL8-2.

Coolix 4100 chiller: This is the newest iteration of the Coolix chiller. Not a lot has changed in terms of function, but because they are newer options for service will be more limited.

Color scheme: This is purely a cosmetic change, but IGS labs do look pretty sharp.

Hardware changes from Q4 of 2015:

• DL9 and RTAC9 computers
• New detector
• New detector power supply
• New electronics in the C1 cabinet

Each of these changes represents incremental improvement in component design and performance but, even taken in aggregate, do not constitute a dramatic difference in the user experience.

Software options: A few software options introduced in the later software levels for the Innova series have carried into the IGS series. Dose SR (Structured Reporting) and Dose Map are the most significant new options on the IGS systems

Why Innova?

Strong parts availability / reasonable parts pricing: With more years under their belt and a much wider install base, third-party parts availability for Innova systems is much greater. This, of course, also means that parts for Innova systems will cost much less than those for IGS systems.

IGS units, specifically the 2015 and newer models with different detectors and DL8-2 or DL9 computers, will be difficult to find parts for for a few more years. Many parts purchases will likely have to be made through GE at significantly higher cost.

Serviceability: IGS units are more limited in terms of third-party service. The Innova series is the bread and butter of any independent GE cath engineer.

High similarity at a far lower price point: When you choose to purchase an Innova, you purchase largely the same system as an IGS, but at a much lower price point

Why IGS 5 series?

Newer dates of manufacture: There are basic advantages to more recent manufacture in terms of wear and tear and component longevity.

Familiar format and use: If your team has used the Innova series, the learning curve to transition to the IGS will be minimal.

Site planning: If you are upgrading from an Innova series system to an IGS, the site planning work is the same.

The Takeaway

For the foreseeable future, used IGS 5 series labs will continue to be rare and, when available, to command high-end prices. For facilities that have the time to wait or the money to spend, an IGS 520, 530, or 540 cath lab will be a fine system with the latest "bells and whistles" and the longevity benefit of a later manufacture date. Those needing a more budget-conscious solution, and sooner, can have virtually the same technology and user experience by choosing a refurbished Innova 2100, 3100, or 4100.
