Intended Use

The Philips IQon Spectral CT is a Computed Tomography X-Ray System intended to produce cross-sectional 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, component parts, and accessories. The IQon Spectral CT system acquires one CT dataset – composed of data from a higher-energy detected x-ray spectrum and a lowerenergy detected x-ray spectrum. The two spectra may be used to analyze the differences in the energy dependence of the attenuation coefficient of different materials. This allows for the generation of images at energies selected from the available spectrum and to provide information about the chemical composition of the body materials and/or contrast agents. Additionally, materials analysis provides for the quantification and graphical display of attenuation, material density, and effective atomic number. This information may be used by a trained healthcare professional as a diagnostic tool for the visualization and analysis of anatomical and pathological structures.

Device Story

Whole-body CT system; acquires dual-energy x-ray transmission data via rotating gantry and detector array; transforms data into cross-sectional images and spectral material analysis. Components include scanner, patient couch, operator console, Spectral Reconstruction System, and Spectral CT Viewer. Used in clinical settings by trained healthcare professionals. Outputs include conventional CT images, monoenergetic images, material density maps (e.g., Iodine/Water, Calcium/Uric Acid), effective atomic number maps, and attenuation curves. Enables material differentiation, beam hardening reduction, and calcium blooming reduction. Assists clinicians in visualizing anatomical/pathological structures and quantifying material composition; improves diagnostic confidence through spectral information.

Clinical Evidence

Clinical evaluation consisted of a qualitative assessment of collected clinical images. The study aimed to ensure images constructed by the system met user needs for the visualization and analysis of anatomical and pathological structures. No specific sample size, sensitivity, or specificity metrics were reported.

Technological Characteristics

Connectivity includes workstation hardware for data acquisition, display, storage, and post-processing.

Indications for Use

Indicated for use as a diagnostic tool for the visualization and analysis of anatomical and pathological structures in patients requiring computed tomography imaging.

The Philips IQon Spectral CT is a whole-body computed Device Description: tomography (CT) X-Ray System featuring a continuously rotating x-ray tube and detectors gantry and multi-slice capability. The acquired x-ray transmission data is reconstructed by computer into cross-sectional images of the body taken at different angles and planes. This device also includes signal analysis and display equipment; patient and equipment supports; components; and accessories. The Philips IQon Spectral CT includes the detector array previously described in K131773 "Modified Brilliance iCT".

> The IQon Spectral CT consists of three main components – a scanner system that includes a rotating gantry, a movable patient couch, and an operator console for control and image reconstruction; a Spectral Reconstruction System; and a Spectral CT Viewer. On the gantry, the main active components are the x-ray high voltage (HV) power supply, the x-ray tube, and the detection system.

> In addition to the above components and the software operating them, the system includes workstation hardware and software for data acquisition; and image display, manipulation, storage, and filming, as well as post-processing into views other than the original axial images. Patient supports (positioning aids) are used to position the patient.

Substantial Equivalence: The Philips IQon Spectral CT has an intended use and technology that are similar to the predicate device.

> As described above, the Philips IQon Spectral CT includes the hardware configuration previously described in K131773 "Modified Brilliance iCT", updated system software, a Spectral Reconstruction System; and a Spectral CT Viewer application.

The IQon Spectral CT system is able to generate conventional (combined) CT images (equivalent to a CT image series from a non-spectral detector CT system) as described in K131773. The scanner software has been updated to a more recent version of software that provides for an easier user workflow (iPatient).

To address the addition of spectral CT imaging capability, a reference device has been identified. Because both devices are able to acquire two CT spectra, each is able to perform various types of spectral analysis, such as:

- Monoenergetic images
- . Materials Basis/Density Pairs, such as
- o 1/ H20
- o I / Ca
- o Ca / Uric Acid
- I Effective Atomic Number
- 트 Material Separation/Differentiation
- I Attenuation Curves
- Density Measurements/Visualization
- Reduction of Beam Hardening
- Reduction of Calcium Blooming

The Summaries of Non-Clinical Testing and Clinical Testing, presented below, provide a brief outline of the testing data that has been presented to demonstrate substantial equivalence.
