Intended Use

The LightSpeed 7.0 CT Scanner System is indicated for head and whole body X-ray Computed Tomography applications.

Device Story

LightSpeed 7.0 CT Scanner System is an evolutionary modification of the LightSpeed 5.0 CT Scanner. The system comprises a gantry, patient table, console, and power distribution unit (PDU), incorporating image acquisition hardware and reconstruction software. It functions as a head and whole-body CT scanner, utilizing X-ray computed tomography to generate diagnostic images. Operated by trained clinical staff in a hospital or imaging center environment, the device transforms X-ray attenuation data into cross-sectional images. These images are displayed on the console for physician review to assist in clinical diagnosis and treatment planning. The device maintains the fundamental operating principles and design of its predecessor, providing diagnostic imaging capabilities for patients requiring CT examinations.

Clinical Evidence

Bench testing only. The device underwent system verification and validation to ensure performance meets specifications, federal regulations, and user requirements. Compliance with industry standards (UL/CSA and IEC) was used to demonstrate safety and effectiveness.

Technological Characteristics

Computed tomography X-ray system. Components: gantry, patient table, console, PDU. Materials and construction equivalent to LightSpeed 5.0. Standards: UL 2601-1, IEC 60601-1, 21 CFR Subchapter J. System includes image acquisition hardware and reconstruction software.

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.

#### DEVICE DESCRIPTION

The LightSpeed 7.0 CT Scanner System is composed of a gantry, patient table, console, and PDU, and includes image acquisition hardware, image acquisition and reconstruction software, and associated accessories. LightSpeed 7.0 is evolutionary modification to LightSpeed 5.0 (K030420) and is designed to be a head and whole body CT scanner incorporating the same basic fundamental operating principles and Indications for Use.

Materials and construction are equivalent to the LightSpeed 5.0 CT Scanner System, which are compliant with UL 2601-1, IEC 60061-1 and associated collateral and particular standards, and 21CFR Subchapter J.

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

### Indications for Use:

The LightSpeed 7.0 CT Scanner System is indicated for head and whole body X-ray Computed Tomography applications.

### Comparison with Predicate:

LightSpeed 7.0 is a modification of the LightSpeed 5.0 CT Scanner System and has identical indications for use. It has the same technological characteristics and operating principles, is indications for active the came to the towns and QA features, and uses the same basic design, construction, and materials.

In the opinion of GE Medical Systems, the LightSpeed 7.0 CT Scanner System is of in the opinion of GE Mouled Systems, includent to currently marketed head and whole body X-ray computed tomography systems that comply with the same or equivalent standards and have the same intended uses. LightSpeed 7.0 will be certified to comply with the X-ray requirements the same intentional accorded as the safety requirements of UL2601-1, and IEC 60601-1 and associated collateral and particular 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 . Regulations, and user requirements.
- Adherence to industry and international standards. (UL/CSA and IEC). .

#### CONCLUSIONS

The LightSpeed 7.0 CT Scanner System, as an evolutionary modification to the currently rno EightSpeed 5.0, 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 7.0 CT System as or botter that to other marketed devices with the same indications for use and meeting similar standards.
