Intended Use

The Brilliance CT is a Computed Tomography X-Ray System intended to produce crosssectional images of the body by computer reconstruction of x-ray transmission data taken at different angles and planes. This device may include signal analysis and display equipment, patient, and equipment supports, components and accessories. The dual energy option allows the system to acquire two CT images of the same anatomical location using two distinct tube voltages and/or tube currents during two tube rotations. The x-ray dose will be the sum of the doses of each tube rotation at its respective tube voltage and current. Information regarding the material composition of various organs, tissues, and contrast materials may be gained from the differences in x-ray attenuation between these distinct energies. This information may also be used to reconstruct images at multiple energies within the available spectrum, and to reconstruct basis images that allow the visualization and analysis of anatomical and pathological materials.

Device Story

Brilliance Dual Energy option is an add-on for Philips Brilliance CT scanners; automates sequential scanning protocols using two distinct tube voltages/currents during two rotations. Input: x-ray transmission data at two energy levels. Processing: computer reconstruction of cross-sectional images; analysis of attenuation differences between energy levels. Output: side-by-side or overlaid images; basis images for material composition visualization. Used in clinical settings by radiologists/technicians. Output assists clinicians in identifying anatomical/pathological structures and characterizing tissue/contrast material composition. Benefits: enhanced diagnostic information regarding material composition compared to single-energy CT.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Computed Tomography X-Ray System (21 CFR 892.1750). Dual-energy acquisition via sequential tube rotations at distinct voltages/currents. Software-based image reconstruction and analysis of attenuation differences. Connectivity via standard CT system architecture.

Indications for Use

Indicated for patients requiring cross-sectional imaging of the body via CT. Used for anatomical and pathological structure visualization, including material composition analysis of organs, tissues, and contrast agents using dual-energy attenuation differences.

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 Name and Classification 2.

| Device Name: | Brilliance Dual Energy option |
|----------------------|----------------------------------|
| Classification Name: | Computed Tomography X-Ray System |

The FDA has classified the Computed Tomography X-Ray System and its accessories as Class II in 21 CFR 892.1750 (Product Code 90 JAK)

#### 3. Predicate Device Information

In the opinion of Philips Medical Systems Inc., the Brilliance Dual Energy option is of comparable type and substantially equivalent to the legally marketed devices currently in commercial distribution, namely: the Philips Brilliance Volume - K060937 and the GE Lightspeed CT750 HD - K081105.

#### 4. Device Description

Philips Healthcare offers a Dual Energy scanning option on the Brilliance CT Scanner. The Brilliance Dual Energy option automates the execution of sequential scanning protocols acquired during the same episode of care using two unique tube voltages and/or currents. The acquired datasets can be displayed side-by-side or overlaid and then analyzed to augment the review of anatomical and pathological structures. Dual energy imaging, by nature of differing x-ray energy values, enables the identification of attenuation differences found in those structures between the two applied energies.

### Intended Use of the device 5.

The Brilliance CT is a Computed Tomography X-Ray System intended to produce crosssectional images of the body by computer reconstruction of x-ray transmission data taken at different angles and planes. This device may include signal analysis and display equipment, patient, and equipment supports, components and accessories.

The dual energy option allows the system to acquire two CT images of the same anatomical location using two distinct tube voltages and/or tube currents during two tube rotations. The x-ray dose will be the sum of the doses of each tube rotation at its respective tube voltage and current. Information regarding the material composition of various organs, tissues, and contrast materials may be gained from the differences in xray attenuation between these distinct energies. This information may also be used to reconstruct images at multiple energies within the available spectrum, and to reconstruct basis images that allow the visualization and analysis of anatomical and pathological materials.

### Comparison to Predicate Devices 6.

In the opinion of Philips Medical Systems (Cleveland), Inc., the Brilliance CT scanner with Dual Energy option is of comparable type and substantially equivalent to the legally marketed devices because it has the similar technological characteristics and subassemblies as the current commercial distribution of Philips Brilliance Volume (K060937) and the GE Lightspeed CT750 HD (K081105).
