GE LightSpeed 16-Slice CT

GE LightSpeed 16 Highlights & Benefits

The GE LightSpeed 16 combines thin-slice acquisition, practical workflow tools, and a compact 70 cm gantry design for routine diagnostic and whole-body CT. As a pre-owned CT scanner platform, available hardware, software, accessories, and advanced applications can vary by system.

Key LightSpeed 16 Capabilities

• • 16 × 0.625 mm submillimeter acquisition
  • 0.5-second fastest rotation
  • HiLight Matrix II detector
  • Up to 35 mm per rotation helical coverage
  • SmartmA automatic tube-current modulation
  • 70 cm (27.6 in) gantry aperture
  • Optional cardiac, vascular, perfusion, lung, colonography, and post-processing applications

This GE LightSpeed CT scanner can be well suited to hospitals, diagnostic imaging departments, and outpatient imaging centers seeking a 16-slice system for established head-to-body imaging workflows. Its relatively compact installation requirements can also benefit facilities working within an existing CT suite.

CT Acquisition & Image Detail

Detector & Thin-Slice Imaging

The GE LightSpeed 16 uses the HiLight Matrix II detector with 21,888 detector elements. Its 16 × 0.625 mm acquisition mode provides thin volumetric data for detailed anatomy, vascular imaging, bone imaging, and multiplanar reconstruction.

Additional detector configurations allow protocols to balance anatomical coverage and reconstructed image thickness according to the examination.

0.5-Second Head-to-Body Scanning

The LightSpeed 16 supports full 360° helical rotation times as fast as 0.5 seconds.

Helical coverage reaches up to 35 mm per rotation depending on detector configuration and pitch, supporting efficient head-to-body and whole-body CT while retaining thin-slice acquisition when greater anatomical detail is required.

Flexible Thin-Slice Reconstruction

The scanner reconstructs images at speeds up to six images per second.

Prospective Multiple Reconstruction can generate multiple reconstruction sets from one acquisition, while GE VariViewer allows thin acquired data to be displayed at different effective slice thicknesses.

This supports detailed thin-section review while also allowing thicker image sets to be created for routine interpretation.

Image Quality & Dose Management

SmartmA Dose Management

SmartmA automatically adjusts tube current according to the selected image-quality target and scan parameters.

Operators set a Noise Index and maximum mA, allowing the scanner to adapt tube current throughout the examination rather than applying the same technique across all anatomy.

The system also provides dose-length product information before acquisition for review during scan preparation.

Artifact Reduction for Challenging Exams

HyperPlane, CrossBeam, and Advanced Artifact Reduction technologies help manage helical, cone-beam, and streak artifacts.

These tools can be particularly useful when imaging dense anatomy or patients with orthopedic hardware.

Patient Access, Table & Workflow

Gantry Access & Patient Positioning

The GE LightSpeed 16 has a 70 cm (27.6 in) gantry aperture and a 50 cm (19.7 in) maximum scan field of view.

Gantry tilt extends to ±30°, providing additional flexibility for head positioning and scan-plane selection. Gantry-mounted controls and alignment lights support patient setup from inside the scan room.

170 cm Table Travel & 450 lb Capacity

The cantilever patient table provides 170 cm (66.9 in) of horizontal travel for head-to-body imaging and supports patient loads up to 450 lb (205 kg).

An adjustable table height, bilateral foot controls, and an integrated IV pole support positioning and contrast-enhanced CT workflow.

Programmable Protocols & Contrast Timing

The LightSpeed 16 uses GE Xtream workflow and Exam Rx protocol tools to streamline examination setup.

Programmable adult and pediatric protocols can help standardize common studies while remaining adjustable for patient-specific needs. SmartPrep supports real-time monitoring of contrast enhancement to help time contrast-enhanced acquisitions.

In-room controls further support efficient positioning and scan preparation.
