Indications for Use
The Precise Image is a reconstruction software application for 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. Precise Image has been evaluated and available on preselected reference protocols for adult subjects. Precise Image is not indicated for use in pediatric subjects. The CT system with Precise Image is indicated for head, whole body and vascular X-ray Computed Tomography applications. These scanners are intended to be used for diagnostic imaging. Precise Image uses an Artificial Intelligence powered reconstruction algorithm that is designed for low radiation dose, provides low noise, and improves low contrast detectability.
Device Story
Precise Image is a reconstruction software application for Philips whole-body CT systems. It processes raw x-ray transmission data acquired at various angles and planes to generate diagnostic images. The device utilizes an AI-powered reconstruction algorithm based on Convolutional Neural Networks (CNN) to reduce radiation dose, lower image noise, and improve low-contrast detectability while maintaining an image appearance similar to traditional Filtered Back Projection (FBP). The software includes five user-adjustable settings allowing radiologists to balance dose reduction and image quality preferences. It is intended for use by clinicians in diagnostic imaging environments. By enabling lower radiation doses without compromising image quality, the device aims to benefit patients through reduced exposure while providing radiologists with high-quality images for diagnostic decision-making.
Clinical Evidence
No external clinical study was required. A comparative image evaluation study was conducted on 55 image set pairs from the subject device and predicate devices (Incisive CT and Brilliance iCT). Six board-certified radiologists evaluated images on a five-point Likert scale for diagnostic confidence, sharpness, noise level, image texture, and artifacts. All images were rated as having good image quality.
Technological Characteristics
Software-based reconstruction application utilizing Artificial Intelligence and Convolutional Neural Networks (CNN). Operates on Philips CT systems. Features five user-adjustable settings for dose/quality optimization. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3, IEC 60601-1-6, IEC 60601-2-44, IEC 62304, ISO 10993-1, and ISO 14971.
