The Philips iCT CT systems 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 equipment supports, components and accessories. The iCT is indicated for head, whole body, cardiac and vascular X-ray Computed Tomography applications in 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.
*Please refer to clinical literature, including the results of the National Lung Screening Trial (N Engl J Med 2011; 365:395-409) and subsequent literature, for further information.
The Philips iCT CT System is a whole-body computed tomography (CT) X-ray system designed for diagnostic imaging. It features a continuously rotating X-ray tube and multi-slice detector gantry, enabling the acquisition of X-ray transmission data from multiple angles and planes. The system reconstructs these data into cross-sectional images using advanced image reconstruction algorithms, supporting a wide range of clinical applications.
The system consists of a gantry, which houses the rotating X-ray tube, detector array, and key imaging subsystems; a patient support couch, which moves the patient through the gantry bore in synchronization with the scan and is available in multiple configurations; an operator console, which serves as the primary user interface for system controls, image processing, and data management; and a Data Measurement System (DMS), which captures X-ray attenuation data to support high-quality image reconstruction.
The provided FDA 510(k) clearance letter for the Philips iCT CT System (K250648) focuses on demonstrating substantial equivalence to a predicate device (K162838) based on hardware and software enhancements.
However, there is no information within this document that describes specific acceptance criteria in terms of algorithm performance metrics (e.g., sensitivity, specificity, AUC) for an AI/ML-driven diagnostic task, nor does it detail a study proving the device meets such criteria in a clinical context.
The document primarily addresses:
- Physical and technical characteristics of the CT system (e.g., spatial resolution, low contrast resolution, noise, scan speeds).
- Safety and performance of system modifications (e.g., OS upgrade, cybersecurity enhancements, new phantom kit) through non-clinical verification and validation activities.
- Substantial equivalence to a predicate device based on these engineering and system-level tests.
The mention of "low dose CT lung cancer screening for the early detection of lung nodules that may represent cancer" refers to a general indication for the CT system itself, not a specific AI/ML diagnostic algorithm for nodule detection or characterization within the system. The note to "refer to clinical literature, including the results of the National Lung Screening Trial" further supports that the clinical efficacy of CT for lung screening is established and not being re-proven by this submission for a new AI feature.
Therefore, I cannot populate the requested table or answer the specific questions about AI/ML study design directly from the provided text, as this information is not present. The document focuses on the CT scanner as the device, not a specific AI-powered diagnostic algorithm within it that would require the detailed studies outlined in your request.
If the "Philips iCT CT System" were to include an AI component with an explicit diagnostic function beyond general image acquisition and display, the FDA submission would typically contain a dedicated section on its performance evaluation, including the types of studies you are asking about. This document does not describe such an AI component or its associated clinical performance study.
