Toshiba Aquilion Lightning 16

Family: Aquilion Lightning · Manufacturer: Toshiba Medical · Modality: CT

The entry trim of the Aquilion Lightning family. 16 detector rows × 0.5 mm = 8 mm Z-axis coverage per rotation. Built for community hospitals, urgent care, veterinary, and global emerging-market installations where a wide-bore CT is needed but full helical-cardiac capability is not. The 16-slice Lightning is the dominant legacy-Toshiba-Aquilion-16 replacement scanner worldwide.

Platform characteristics

16-slice detector at the Aquilion family's standard 0.5 mm element pitch.
75 cm bore — wider than every competing 16-slice scanner in its market segment, which mostly ship 70 cm bores. Real differentiator for bariatric and ER trauma work.
AIDR 3D iterative reconstruction standard. AiCE deep-learning recon not available on 16-slice trim.
PUREViSION Optics tube design — extended life at the duty cycles community CT actually runs.
Reduced footprint and power — drops into rooms previously hosting Toshiba Aquilion 16, Siemens Emotion 16, GE BrightSpeed 16. No room rebuild required in most replacements.
Console-based workflow with Vitrea integration available.

Specs

16 slices · 0.5 mm detector element pitch · 8 mm Z-axis coverage per rotation
75 cm gantry aperture

AIDR 3D iterative reconstruction
PUREViSION-lineage tube
Standard Vitrea console workflow
Power / siting requirements as configured for entry-tier CT rooms

Clinical positioning

General radiology — head, chest, abdomen, pelvis, extremities, basic spine.
Urgent care and ED in community hospital settings — straightforward trauma, stones, basic vascular.
Veterinary CT — the wide bore handles equine and large-animal work that 70 cm bores can't.
NOT for cardiac CT — slice count and rotation time are insufficient for coronary work. Push customers to a Lightning 64 / 80 if they're scanning hearts.
NOT for advanced perfusion or onco volumetrics — same reason.

What's different vs the Lightning 32

Slice count. The 32 doubles the Z-axis coverage per rotation (16 mm vs 8 mm), reducing helical scan times for chest/abdomen by roughly half.
Throughput. 32-slice cuts ~30–40% off study time on common protocols. Matters in ED workflow.
Cardiac. Neither 16 nor 32 is a true cardiac CT. The 32 with the right trim can do basic Calcium scoring; the 16 cannot reliably.
Refurb premium. Lightning 32s carry roughly 30–40% more in the refurb market than Lightning 16s of the same vintage.

Top failure modes (16-slice trim)

Shared with the broader Aquilion Lightning family. The 16 in particular sees:

Console PC drift / aging Windows builds — entry-tier trim shipped with longer-lived console PCs that age out before the gantry does. Standard refurb item.
Tube end-of-life on high-volume sites — community CT often runs the tube hard. Track HU counts on incoming refurb units.
Foot pedal / table cabling — patient-table-side cabling is the most common service call on community-hospital Lightnings.
DICOM AE-title misconfigurations post-PACS migration — the Lightning is fussy about case sensitivity in older firmware.

Acceptance checklist (refurb purchase)

Tube HU counter printout — under 500k HU is safe; 500k–1M is mid-life; >1M plan for tube reserve.
Generator calibration report within 30 days
Detector channel report — flag any failed channels
Software version recorded (drives parts compatibility)
Console / workstation boot full cycle without errors
AIDR 3D licensed and active
DICOM C-Echo / C-Store passes against your PACS test environment
All four wheel brakes / table motion limits engage
Foot switch and patient-side controls functional

Relationship to siblings

Aquilion Lightning 32 — next tier up.
Aquilion Lightning 64 — mainstream rad workhorse.
Aquilion 16 — older Toshiba-era 16-slice (different platform, pre-Lightning).
