GE Signa Artist 1.5T
Manufacturer: GE HealthCare · Modality: MRI
Current GE 1.5 T wide-bore MRI. Positioned as the mainstream clinical-1.5T platform in the Signa family above Signa Explorer and below the 3 T Signa Premier. Ships as Signa Artist and Signa Artist AIR Edition, with the AIR Edition bundling the AIR coil family.
Platform highlights
- 70 cm wide bore — bariatric, claustrophobic-friendly, consistent with the current Signa family chassis.
- 50 × 50 × 50 cm³ field of view at the 70 cm bore.
- 500 lb table weight capacity — broad patient-size accommodation.
- Direct Digital Interface — up to 128 RF receive channels, digitization closer to the coil for reduced analog noise.
- AIR coil platform (AIR Edition) — conformal, blanket-like coils that replace rigid body / head / spine coils for many exams. Meaningful workflow change vs legacy coil handling.
- AIR Recon DL — deep-learning image reconstruction; reduces scan time up to ~50% or raises resolution at matched scan time.
- MAGiC — multi-contrast single-acquisition sequence that produces T1, T2, PD, T2-FLAIR, T1-FLAIR, STIR from one scan. Clinically compelling where multi-contrast protocols dominate throughput.
- HyperSense, HyperBand — compressed sensing and simultaneous multi-slice acceleration.
- SIGNAWORKS host — current GE MR operating environment.

Clinical positioning
Workhorse clinical 1.5 T — neuro, MSK, body, cardiac, breast, prostate. Direct competitor to the Siemens MAGNETOM Sola and Philips Ingenia 1.5T on new orders. Preferred in:
- High-volume imaging centers where MAGiC and AIR Recon DL shorten total room time per exam.
- Orthopedic / MSK-heavy practices with high throughput on 1.5 T knee, shoulder, spine protocols.
- Bariatric / claustrophobic-friendly siting where the 70 cm bore + 500 lb table matter.
- AIR coil workflow adopters where the conforming-coil architecture changes exam setup time.
Relationship to siblings
- Signa Voyager 1.5T — related 1.5 T wide-bore sibling in the Signa portfolio.
- Signa Explorer 1.5T — lower-tier 1.5 T sibling.
- Signa HDxt 1.5T — legacy predecessor (60 cm bore).
- Signa Premier 3T — 3 T counterpart in the current Signa family.
