Description
GE LightSpeed VCT 64-Slice CT Scanner
The GE LightSpeed VCT 64 is a 64-slice multislice CT scanner engineered for high-resolution whole-body imaging
with strong performance in cardiac, neuro, trauma, and routine diagnostic exams.
Its fast acquisition and volume coverage make it a versatile clinical workhorse for mid-to-high patient throughput.
Core Technical Specifications
Imaging & Performance
-
Slice count: 64 slices per gantry rotation — provides volumetric imaging with thin section detail.
-
Detector coverage per rotation: ~40 mm (64 × 0.625 mm).
-
Gantry rotation speeds: ~0.35–0.45 s (configurable).
-
Minimum temporal resolution: ~175 ms (important for cardiac imaging).
-
Gantry aperture: 70 cm — large bore for patient comfort and broader fields of view.
-
Maximum beam width: 4 cm coverage per rotation.
-
Voxel resolution: Sub-millimeter detail (~0.35–0.625 mm).
X-Ray & Electronics
-
X-ray tube capacity: ~8.0 MHU (tube heat capacity).
-
kV range: 80–140 kVp.
-
mA range: ~10–800 mA (depending on generator).
-
Generator power: ~85–100 kW range.
-
Reconstruction matrix: Commonly 512 × 512.
Table & Room
-
Table weight limit: ~500 lbs (~227 kg).
-
Table travel range: ~43–99 cm vertical, ~203 cm longitudinal.
-
Suggested minimum room size (approx): ~20 × 11.5 × 7 ft (~6 × 3.5 × 2.1 m).
Clinical Features & Technology
✔ SnapShot Pulse™ – enables cardiac imaging in just a few heartbeats (e.g., whole heart in ~5 beats).
✔ Advanced reconstruction & workflow options – SmartPrep, SmartStep, Connect Pro, Direct-3D, VolumeViewer could be included as software packages.
✔ ECG-gated cardiac imaging packages – ECG Viewer, CardIQ SnapShot, SmartScore Pro (options dependent on software).
✔ Iterative reconstruction dose reduction – improvements in image clarity at lower radiation doses (may include ASIR in later configurations).
✔ Broad clinical flexibility – suitable for cardiac, neuro, trauma, pulmonary, and angiographic protocols.
