No
The summary describes a standard CT system with image reconstruction and post-processing capabilities, but there is no mention of AI or ML in the intended use, device description, or performance studies. The focus is on the mechanical and computational components for image acquisition and reconstruction, which are traditional CT technologies.
No
The device is described as a diagnostic imaging system, designed to produce images for diagnostic purposes and lung cancer screening, not to treat or cure a disease.
Yes
The "Intended Use / Indications for Use" section explicitly states, "These systems are intended to be used for diagnostic imaging..." and "for the early detection of lung nodules that may represent cancer."
No
The device description explicitly lists multiple hardware components including a gantry, patient support (couch), console (containing a host computer and image reconstruction computer), and workstation hardware. It is a complete CT system, not just software.
Based on the provided text, the Philips CT Big Bore is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Function: The Philips CT Big Bore is a Computed Tomography X-Ray System. It produces images of the inside of the body by using X-rays and computer reconstruction. It does not analyze specimens taken from the body.
- Intended Use: The intended use clearly states it's for "diagnostic imaging" and "low dose CT lung cancer screening" by producing images of the head and body.
Therefore, the Philips CT Big Bore falls under the category of medical imaging devices, not In Vitro Diagnostic devices.

Intended Use / Indications for Use
The Philips CT Big Bore is a Computed Tomography X-Ray System intended to produce images of the head and body by computer reconstruction of x-ray transmission data taken at different angles and planes. These devices may include signal analysis and display equipment, patient and equipments and accessories. These systems are indicated for head and whole body X-ray Computed Tomography applications in oncology, vascular and cardiology, for patients of all ages.
These scanners are intended to be used for diagnostic imaging and for low dose CT lung cancer screening for the early detection of lung nodules that may represent cancer*. The screening must be performed within the established inclusion criteria of programs / protocols that have been approved and published by either a governmental body or professional medical society.

Device Description
The Philips CT Big Bore is available in three system configurations, the Oncology configuration the Radiology (Base) configuration, and the new Sliding Gantry configuration.
The main components (detection system, the reconstruction algorithm, and the x-ray system) that are used in the Philips CT Big Bore have the same fundamental design characteristics and are based on comparable technologies as the predicate.
The main system modules and functionalities are:
-
- Gantry. The Gantry consists of 4 main internal units:
- a. Stator a fixed mechanical frame that carries HW and SW
- b. Rotor A rotating circular stiff frame that is mounted in and supported by the stator.
- c. X-Ray Tube (XRT) and Generator fixed to the Rotor frame
- d. Data Measurement System (DMS) a detector array, fixed to the Rotor frame
-
- Patient Support (Couch) supports the patient in a stationary position while the gantry moves in and out on a carriage.
-
- Console A two part subsystem containing a Host computer and display that is the primary user interface and the Common Image Reconstruction System (CIRS) - a dedicated, powerful image reconstruction computer
In addition to the above components and the software operating them, each system includes workstation hardware and software for data acquisition, 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.
The Sliding Gantry Configuration provides the following features.
- . The patient table is stationary during the scan.
- . Patient is located on the stationary table.
- To perform imaging, CT gantry rides on a carriage and moves over the patient.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The proposed Philips CT Big Bore Sliding Gantry Configuration did not require a clinical study since substantial equivalence to the legally marketed predicate device was proven with the verification/validation testing.
Bench testing included basic CT performance tests on phantoms, safety tests and software tests for functional and non-functional attributes of the proposed Philips CT Big Bore Sliding Gantry Configuration.
| CT Performance Metric | Values and ranges measured on phantoms |
|---|---|
| MTF | Cut-off: High Mode 16±2lp/cm; Standard Mode: 13±2 lp/cm |
| CTDIvol | Head: 10.61mGy/100mAs±25%; Body: 5.92mGy/100mAs±25% at 120kV |
