Toshiba Aquilion Lightning 32

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

The intermediate trim of the Lightning family. 32 detector rows × 0.5 mm = 16 mm Z-axis coverage per rotation. Sized for small-to-mid hospitals and outpatient imaging centers that need more throughput than a 16-slice provides but don't require full cardiac CT. The Lightning 32 is the practical floor for any site doing routine ED CT at clinical-volume scale.

Platform characteristics

  • 32-slice detector at the Aquilion 0.5 mm element pitch.
  • 75 cm bore — same wide-bore advantage as every other Lightning trim.
  • AIDR 3D iterative reconstruction standard. AiCE not available on 32-slice trim.
  • Faster rotation than the Lightning 16 on most regional trims — meaningful for chest CT and ED throughput.
  • PUREViSION Optics tube lineage.
  • Same footprint and power envelope as the 16 — the 32 is a drop-in upgrade path with no room rework.

Specs

  • 32 slices · 0.5 mm detector pitch · 16 mm Z-axis coverage per rotation
  • 75 cm gantry aperture
  • ~0.75 sec minimum rotation (faster trims available regionally)
  • AIDR 3D iterative reconstruction
  • PUREViSION-lineage tube
  • Vitrea console workflow

Clinical positioning

  • Mainstream general radiology — head, chest, abdomen, pelvis, spine, extremities at full clinical volume.
  • Routine ED CT — trauma, stones, head bleeds, basic CT angio of large vessels.
  • Calcium scoring — feasible on appropriately spec'd trims; coronary CTA still belongs on the 64 or 80.
  • Imaging center mid-tier — the price/performance sweet spot for sites that need throughput but not cardiac.

What's different vs adjacent variants

vs Lightning 16:

  • Doubles Z-axis coverage per rotation (16 mm vs 8 mm)
  • Cuts roughly 30–40% off chest/abdomen study time
  • Calcium scoring becomes practical
  • ~30–40% refurb-market premium over the 16 for same vintage

vs Lightning 64:

  • Half the Z-axis coverage per rotation (16 mm vs 32 mm)
  • No coronary CTA — rotation time + slice count fall short for diagnostic-quality cardiac
  • ~25–35% lower refurb price point than Lightning 64
  • Same gantry, same room footprint — the upgrade path is purely detector + reconstruction firmware

Top failure modes (32-slice trim)

Shared with the family. Specific to 32-trim:

  1. Reconstruction PC overload on heavy iterative-recon protocols — older trims ship with reconstruction hardware that ages faster than the gantry. Watch for queue backups.
  2. DICOM transfer-syntax mismatches on chest CT volumes — the larger volumes from 32-slice protocols stress legacy PACS more than 16-slice did. Force Implicit VR Little Endian on the SCP side if you see store failures.
  3. Tube life on high-volume ED sites — 32-slice in a 24-hour ED runs the tube hard. Track HU counts.
  4. Backup battery / console UPS — the higher draw of 32-slice reconstruction can trip undersized backup units on legacy install rooms.

Acceptance checklist (refurb purchase)

  • Tube HU counter printout
  • Generator calibration report (current, within 30 days)
  • Detector channel report — all 32 active, no dropped channels
  • Reconstruction PC spec recorded — flag if upgraded out-of-warranty
  • AIDR 3D license active
  • Software version captured for parts compatibility
  • DICOM C-Echo / C-Store / C-Find tested against your PACS
  • Console + workstation full power cycle clean
  • Patient-table motion + emergency stop verified
