Intended Use

The GE LightSpeed CT750 HD Computed Tomography X-ray system is intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data taken at different angles and planes, including Axial, Cine, Helical (Volumetric), Cardiac, Spectral, and Gated acquisitions for all ages. These images may be obtained either with or without contrast. This device may include signal analysis and display equipment, patient and equipment supports, components and accessories. This device may include data and image processing to produce images in a variety of trans-axial and reformatted planes. Further the images can be post processed to produce additional imaging planes or analysis results. The GE LightSpeed CT750 HD CT Scanner System is indicated for head, whole body, cardiac and vascular X-ray Computed Tomography applications. The device output is a valuable medical tool for the diagnosis of disease, trauma, or abnormality and for planning, guiding, and monitoring therapy. If the spectral imaging option is included on the system, the system can acquire CT images using different kV levels of the same anatomical region of a patient in a single rotation from a single source. The differences in the energy dependence of the attenuation coefficient of the different materials provide information about the chemical composition of body materials. This approach enables images to be generated at energies selected from the available spectrum to visualize and analyze information about anatomical and pathological structures.

Device Story

GE LightSpeed CT750 HD (LightSpeed 8.0) is a whole-body CT scanner consisting of gantry, patient table, operator console, and computer. It acquires X-ray transmission data at various angles/planes (Axial, Cine, Helical, Cardiac, Spectral, Gated). System transforms raw X-ray data via computer reconstruction into cross-sectional images. Spectral imaging option utilizes different kV levels in a single rotation to analyze material attenuation coefficients and chemical composition. Used in clinical settings by trained professionals; output displayed on console for diagnostic assessment, therapy planning, and monitoring. Evolutionary modification of LightSpeed 7.1; includes new 64-slice detector, updated hardware, firmware, and reconstruction software. Benefits include improved visualization of anatomical/pathological structures through spectral analysis and high-definition imaging.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by bench testing, system verification, and validation to ensure performance to specifications and compliance with international safety standards (UL/IEC) and federal regulations (21 CFR Subchapter J).

Technological Characteristics

Whole-body CT scanner; 64-slice detector. Materials compliant with UL 60601-1 and IEC 60601-1. Energy source: X-ray. Spectral imaging uses multi-kV acquisition from a single source. Connectivity: operator console interface. Software-based image reconstruction and processing. Complies with 21 CFR 1020.30 and 1020.33 radiation safety standards.

Indications for Use

Indicated for head, whole body, cardiac, and vascular CT imaging in patients of all ages. Used for diagnosis of disease, trauma, or abnormality and for planning, guiding, and monitoring therapy. Images may be acquired with or without contrast.

Regulatory Classification

Identification

A computed tomography x-ray system is a diagnostic x-ray system intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from the same axial plane taken at different angles. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

GE LightSpeed 7.1 CT Scanner System (K061817)

## DEVICE DESCRIPTION

The GE LightSpeed CT750 HD CT Scanner System (aka LightSpeed 8.0) is composed of a gantry, patient table, operator console, computer, and PDU and includes image acquisition hardware, image acquisition and reconstruction software, associated accessories and connections/interfaces to accessories. The GE LightSpeed CT750 HD Scanner System is an evolutionary modification to LightSpeed 7.1 (K061817). It is developed from the hardware platform of LightSpeed 7.1 32/64 slice system by adding new application features that involve changes in hardware, software, firmware, recon, and scan mode.

The GE LightSpeed CT750 HD Scanner System is designed to be a head and whole body CT scanner incorporating the same basic fundamental operating principles and similar Indications for Use. Materials and construction are equivalent to our existing marketed products, which are compliant with UL 60601-1, IEC 60601-1 and associated collateral and particular standards, and 21CFR Subchapter J.

#### Indications for Use:

The GE LightSpeed CT750 HD Computed Tomography X-ray system is intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data taken at different angles and planes, including Axial, Cine, Helical (Volumetric), Cardiac, Spectral, and Gated acquisitions for all ages. These images may be obtained either with or without contrast. This device may include signal analysis and display equipment, patient and equipment supports, components and accessories.
