The summary describes a standard CT system with spectral capabilities for material analysis and image reconstruction. There is no mention of AI or ML in the intended use, device description, or performance studies. The focus is on the hardware and spectral data processing.
No
Explanation: The device is explicitly described as a "diagnostic tool for the visualization and analysis of anatomical and pathological structures," not for treating conditions.
Yes
The "Intended Use / Indications for Use" section explicitly states, "This information may be used by a trained healthcare professional as a diagnostic tool for the visualization and analysis of anatomical and pathological structures."
No
The device description explicitly details multiple hardware components including a gantry, patient couch, operator console, x-ray tube, and detection system, in addition to the software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Philips IQon Spectral CT is a medical imaging device that uses X-rays to create cross-sectional images of the body. It analyzes the interaction of X-rays with the body's tissues in vivo (within the living body), not in vitro (outside the body).
- Intended Use: The intended use clearly states it's for producing images of the body and providing information about the chemical composition of body materials and/or contrast agents within the body.
- Device Description: The description details a system that interacts directly with the patient (gantry, patient couch, X-ray tube, detector system).
While the device provides information about the chemical composition of body materials, this is done through the analysis of X-ray attenuation within the body, not through testing samples taken from the body. Therefore, it falls under the category of medical imaging devices, not IVDs.

Intended Use / Indications for 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 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 lower- energy detected x-ray spectramay 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 Description
The Philips IQon Spectral CT is a whole-body computed 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.
