GE Innova 4100-IQ

Family: GE Innova · Modality: Interventional X-Ray

Large-format single-plane interventional platform. 40 × 40 cm flat-panel detector at 2k × 2k pixel resolution, 100 kW high-frequency generator, Performix 160A tube, and the GE AutoEx dose-management control chain. Sized for the full range of vascular and interventional applications — cardiac, peripheral, abdominal, neuro — on one room. Succeeded in current GE new-order catalog by the Discovery IGS platform (IGS 520 / 630 / 740), but Innova 4100-IQ remains a dominant platform in the global install base.

Platform highlights

41 cm detector (40 × 40 cm active FOV) — one of the larger single-plane IR detectors of its generation. Accommodates long coverage in peripheral runs and broad framing for thoracic / abdominal angio.
2048 × 2048 pixel matrix — 4× the pixel count of conventional fluoroscopy; translates to finer wire / stent / microcatheter visualization.
Up to 30 frames per second — adequate for cardiac cineangiography and high-frame neuro runs.
GE AutoEx dose control — automatic exposure control that reduces patient dose up to ~40% at matched image quality per OEM datasheet claims.
Performix 160A tube — 160 kW-class anode with liquid-metal-bearing design; established GE IR tube.
Floor-mounted L-arm + offset C-arm geometry — 3-axis isocentric positioner; the offset C keeps the table clear for anesthesia and operator access.

Cardiac, vascular, neuro workflow

Cardiac — coronary angiography, PCI, TAVR, structural-heart procedures at the standard cardiac frame-rate profile. Paired with GE Mac-Lab haemodynamic systems in most deployments.
Peripheral vascular — bolus-chase runs, SFA / popliteal / BTK angioplasty, carotid stenting.
Neuro interventional — cerebral angiography, aneurysm coiling, stroke thrombectomy with rotational 3D acquisition.
Abdominal IR — TACE, Y-90, embolization with CBCT option.

ClarityIQ and dose-management relationship

GE positions its dose-reduction program as AutoEx + Automated Exposure + grid-controlled pulsed fluoroscopy, parallel to Philips' ClarityIQ program on the Allura Xper platform. The technical approach differs — neither is a simple re-badge — but the clinical conversation (match image quality while reducing patient and operator dose) is the same industry-wide.

Clinical positioning

Universal IR room — cardiac plus peripheral plus neuro plus abdominal IR on a single platform.
Hospital-class cath lab — the 40 × 40 detector and 100 kW generator suit busy hospital-grade procedural volumes.
Primary stroke center — supports rotational angiography and CBCT workflows for thrombectomy.

Relationship to siblings

Innova 2100 / 2100-IQ — 20 × 20 cm cardiac-focused sibling. Cardiac-only rooms picked the 2100 class for footprint and cost; 4100-IQ is the full-capability universal room.
Innova 3100 / 3100-IQ — 30 × 30 cm intermediate sibling, cardiac + limited peripheral.
Innova 4100 (non-IQ) — predecessor-class without the IQ dose-management generation.
Discovery IGS 520 / 630 / 740 — GE's successor mobile-C-arm-style IR platform with motorized rail-mount gantry. Different chassis architecture than the Innova L-arm/C-arm.
