Free yourself from the rails

Free yourself from the constraints of fixed ceiling-mounted systems’ rails with the Discovery IGS* 740 mobile angiography system. The untethered Discovery IGS 740 offers amazing siting and room design flexibility. Practice with exceptional comfort and control with Discovery’s rail-free design and flexible C-arm positioning. And its ample detector covers large anatomies in both 2D and 3D.

With the Discovery IGS 740: 

  • Put yourself at the center of your procedures with liberating rail-free design
  • Design your room with amazing flexibility
  • See large anatomies in one view with an exceptionally large detector

Put yourself at the center of your procedures.

With nothing in your way, you can image the anatomy of interest easily, position your monitors freely, and access your patients completely from the left or right side on the Discovery IGS 740.

Liberating rail-free design

The Discovery IGS 740’s swiveling wheeled gantry moves freely on the floor, not on the ceiling, eliminating overhead rails. So you can place your monitors exactly where you need them for comfortable viewing without straining.

Discovery IGS 740 ample wide-bore C-arm

Ample wide-bore C-arm

With a full 129 cm (50 in.) of space between the tube and the detector, you can image large patients easily, achieve steep angulations conveniently, and perform off-center 3D acquisition to image the borders of the liver or the skin line.

Dedicated arm imaging positions1

Perform procedures such as left arm fistulograms comfortably with the Discovery IGS 740’s dedicated arm imaging positions.

See large anatomies in one view.

Cover large anatomies such as the liver or both legs simultaneously, with fewer runs than smaller detectors, for efficient use of contrast and dose.

An exceptionally large detector

With its broad 41 x 41 cm (16.1 in) digital detector, the Discovery IGS 740 system boasts one of the largest fields of view for interventional imaging. Moreover, the GE-proprietary digital detector delivers one of the industry’s highest levels of DQE, the accepted measure of X-ray detector dose efficiency.

Extended coverage in 2D

With InnovaBreeze1*, take full advantage of the Discovery IGS 740’s very large field-of-view and follow the contrast bolus in both legs in real time using variable panning speed control.

Discovery IGS 740 large organs in 3D

Large organs in 3D

Combine the wide-bore C-arm and the 41 x 41 cm (16.1 in) digital detector, and see large organs like the liver in 3D. Then use FlightPlan for Liver1 to help you identify tumor-feeding vessels in a few clicks and be selective during your liver embolization.

Design your room with amazing flexibility.

By eliminating the rails of ceiling-mounted systems, the Discovery IGS 740 frees up your ceiling entirely for more flexibility in designing your room.

Drawing the ideal room

With no rails on the ceiling blocking where to position ceiling-mounted ancillaries, the Discovery IGS 740 gives you flexibility to draw the location of your monitors, lights, and rad-shields where you need them to be. And with two customizable parking positions, the Discovery IGS 740 adapts to suit your room size and shape.

No reinforced ceiling structure needed

With the mobile Discovery IGS 740 system, there’s no need for long and complex
infrastructure improvements to reinforce your room’s ceiling structure.

 Discovery IGS 740 precious space

Siting in precious space

Whether you’re building a new room, re-purposing an existing room, or re-configuring a small room, the Discovery IGS 740 lets you use precious space efficiently. Fit the Discovery IGS 740 in rooms as small as just 35 square meters (377 square feet), for a wider choice of siting options in situations where space is at a premium.


Power up your clinical decision making

The interventional field is growing with ever-expanding capabilities and migration to less invasive, safer and more cost-efficient procedures. With the new generation of GE's advanced interventional imaging software solutions, ASSIST, you can expand your clinical versatility and successfully plan, guide and assess increasingly sophisticated procedures with greater precision and dose efficiency.

Liver embolization

To deliver therapeutic material to tumors during trans-arterial chemoembolization therapy, it is essential to identify the liver vessels accurately. But the liver’s complex vasculature can make precise identification of tumor-feeding vessels in 2D and 3D images a challenge, often requiring significant time, radiation, and contrast media.


FlightPlan for Liver helps you be selective during your liver embolization procedure. It automatically highlights vessels traveling from the catheter tip to the vicinity of a liver hypervascular lesion in few clicks.


Once ready, you can send the FlightPlan for Liver 3D model to Vision 2 with a single click and use it as a 3D roadmap to guide catheters across tortuous vessels and bifurcations, helping you perform the embolization with confidence.


A post-operative DSA acquisition helps you determine the success of the embolization with no contrast agent leakage in the hypervascular lesion.

Needle ASSIST2

Performing needle procedures in the interventional suite frees up your CT system and provides exceptional access to the patient. However, under fluoroscopic guidance, it may be challenging and time-consuming to find the right entry point and advance the needle while avoiding critical structures.




Define optimal needle entry points and pathways directly on oblique CBCT cross sections.

All at table side, visualize and correct mis-registrations in both translation and rotation.

With Stereo 3D, visualize reconstructed 3D needle on CBCT oblique view from 2 fluoroscopic images with precision.



1. Option

2. Needle ASSIST solution includes TrackVision 2, stereo 3D and requires AW workstation with Volume Viewer, Volume Viewer Interventional. These applications are sold separately.

*The Discovery IGS 740 has the widest bore (distance between the tube cover to detector cover) of the major players’ interventional angiography systems used for imaging in the field of interventional radiology & oncology procedures.
