Toshiba Aquilion Lightning 64

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

The volume tier of the Lightning family — 64 slices in the same wide-bore, reduced-footprint chassis. 64 detector rows × 0.5 mm = 32 mm Z-axis coverage per rotation. This is the mainstream-rad workhorse Lightning: enough slices for diagnostic-quality coronary CTA, enough rotation speed for cardiac protocols, all in a community-hospital-friendly install envelope.

Platform characteristics

  • 64-slice detector at the Aquilion 0.5 mm element pitch.
  • 75 cm bore — wide-bore standard across the family.
  • Sub-second rotation on standard trims — cardiac-capable.
  • AIDR 3D Enhanced iterative reconstruction; AiCE deep-learning recon available on newer trims (but not standard on 64 — confirm at quote).
  • PUREViSION Optics tube lineage.
  • Reduced footprint and power envelope shared with the rest of the Lightning line.

Specs

  • 64 slices · 0.5 mm detector pitch · 32 mm Z-axis coverage per rotation
  • 75 cm gantry aperture
  • Sub-second rotation (~0.5 sec class on standard trims)
  • AIDR 3D / AIDR 3D Enhanced iterative reconstruction
  • AiCE deep-learning recon — available on newer trims (not standard, optional license)
  • PUREViSION-lineage tube
  • Vitrea console + dedicated reconstruction workstation

Clinical positioning

  • Full-service community hospital CT — every protocol type except the most advanced perfusion / volumetric work.
  • Coronary CTA — diagnostic-quality on the 64 with appropriate cardiac protocols and beta-blocker prep. The Lightning 64 is the floor for serious cardiac CT.
  • CT angiography — peripheral, abdominal, head/neck. 32 mm Z-axis coverage handles standard CTA volumes in reasonable times.
  • Outpatient imaging center mid-tier — replaces aging Toshiba Aquilion 64s, GE LightSpeed VCTs, Siemens SOMATOM Definition AS at the imaging-center upgrade cycle.
  • Light interventional / biopsy — the 75 cm bore and standard fluoro mode handle most CT-guided procedures.

What's different vs adjacent variants

vs Lightning 32:

  • True cardiac CT (coronary CTA, calcium scoring, basic functional)
  • Twice the Z-axis coverage per rotation (32 mm vs 16 mm)
  • Sub-second rotation enables cardiac gating
  • Larger reconstruction footprint (more capable workstation)
  • ~25–35% refurb-market premium over the 32 for same vintage

vs Lightning 80:

  • 80 has 25% more detector rows + faster rotation on its top trims
  • 80 standard with AiCE deep-learning recon; 64 only on optioned trims
  • 80 is the cardiac-preferred Lightning when budget allows; 64 is the cardiac-feasible Lightning when budget controls
  • 80 carries a meaningful refurb premium (still primarily new-only as of current production)

Top failure modes (64-slice trim)

  1. Cardiac-protocol detector calibration drift — the 64 sees more cardiac volume than smaller trims, and gated-cardiac protocols expose detector calibration issues earlier. Schedule recalibration on cardiac-heavy sites annually rather than on the manufacturer interval.
  2. Reconstruction workstation thermal load — 64-slice cardiac sets and AIDR 3D Enhanced sustained workload run the workstation hot. Watch for fan / dust issues on units coming out of warmer climates.
  3. Tube life on cardiac-heavy sites — coronary CTA protocols are tube-intensive. Track HU counts; expect shorter tube life on cardiac-volume sites than on routine-rad-only sites.
  4. DICOM SR (Structured Report) integration with PACS — Calcium scoring SRs are notorious for not rendering correctly on legacy PACS. Test in advance.

Acceptance checklist (refurb purchase)

  • Tube HU counter — flag any unit over 800k HU on cardiac-heavy install
  • Generator calibration current
  • Cardiac gating accuracy verified (ECG sync waveform check)
  • All 64 detector channels active
  • AIDR 3D / AIDR 3D Enhanced license confirmed; AiCE license confirmed if quoted
  • Reconstruction workstation spec / firmware recorded
  • Software version captured
  • DICOM C-Echo / C-Store / C-Find / C-Move tested against your PACS
  • Cardiac protocols tested with phantom acquisition
  • Console + workstation power cycle full-clean
