Intended Use

The LightSpeed 4 CT Scanner System is indicated for head and whole body X-ray Computed Tomography applications.

Device Story

LightSpeed 4.0 CT Scanner System is a diagnostic imaging device consisting of a gantry, patient table, console, and computer. It utilizes X-ray technology to acquire cross-sectional images of the head and whole body. The system features a multi-slice solid-state detector with thinner detector elements, enabling the acquisition of 16 slices per rotation. Operated by trained clinicians in a clinical setting, the device processes raw X-ray data to reconstruct images for diagnostic review. The output allows physicians to visualize internal anatomical structures, aiding in clinical decision-making and diagnosis. The system is designed to provide improved imaging capabilities compared to previous iterations while maintaining established safety and performance standards.

Clinical Evidence

Bench testing only. The device underwent system verification and validation to ensure performance to specifications, Federal Regulations, and user requirements. Compliance with industry and international standards (UL 2601-1, IEC 60601-1, 21 CFR 1020.30, 21 CFR 1020.33) was confirmed.

Technological Characteristics

Computed tomography X-ray system. Components: gantry, patient table, console, computer. Detector: multi-slice solid-state with thin elements. Standards: UL 2601-1, IEC 60601-1, 21 CFR Subchapter J. Energy source: X-ray. Connectivity: standard clinical imaging system architecture.

Indications for Use

Indicated for head and whole body X-ray Computed Tomography applications in patients requiring diagnostic imaging.

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.

#### PRODUCT IDENTIFICATION

| Name: | LightSpeed 4.0 CT Scanner System |
|----------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Classification Name: | Computed Tomography X-ray System |
| Manufacturer: | General Electric Medical Systems<br>16800 W. Ryerson Road<br>New Berlin, WI 53151 |
| Distributor: | Same as Manufacturer |
| Marketed Devices: | The LightSpeed 4.0 CT Scanner System is of comparable type and<br>substantially equivalent to currently marketed Computed<br>Tomography X-ray Systems that comply with the same or equivalent<br>standards and have the same intended uses. |

### DEVICE DESCRIPTION

The LightSpeed 4.0 CT Scanner System is composed of a gantry, patient table, console, computer, and associated accessories.

Materials: Materials and construction are equivalent to the LightSpeed 3.0 CT Scanner System (K002978) are compliant with UL 2601-1, IEC 60061-1, and 21CFR Subchapter J.

Design: The system is designed to be a head and whole body CT scanner utilizing a new solid state detector, an intuitive Operator Console, and the same tube and similar features to the LightSpeed 3.0 CT Scanner System (K002978), but now capable of imaging 16 slices per rotation. The system will use a new multi-slice detector having thinner detector elements.

{1}------------------------------------------------

#### Indications for Use:

The LightSpeed 4.0 CT Scanner System is indicated for head and whole body X-ray Cor Tomography applications.

#### Comparison with Predicate:

It is the opinion of GE Medical Systems that the LightSpeed 4.0 CT Scanner System is of a type and substantially equivalent to currently marketed head and whole body X-ray computed tomography systems with respect to design, material composition, energy source, and radiation characteristics. It will comply with the X-ray requirements of 21CFR1020.30 and1020.33, as well as the safety requirements of UL2601-1, IEC 60601-1 and collateral standards.

#### Adverse Effects on Health:

Potential electrical, mechanical and radiation hazards are identified in a risk management summary (hazard analysis) and controlled by:

- System verification and validation to ensure performance to specifications, Federal . Requlations, and user requirements.
- Adherence to industry and international standards. (UL/CSA and IEC). .

#### CONCLUSIONS

The LightSpeed 4.0 CT Scanner Systems does not result in any new potential safety risks and performs as well as or better than devices currently on the market. GE considers the LightSpeed 4.0 CT System to be equivalent to other marketed devices with the same indications for use and meeting similar standards.
