Intended Use

Comprehensive software package for visualization and analysis of thoracic CT datasets, which is intended to help the reading physician to analyze regions of the lung, such as nodules and other lung parameters, and to generate an automatic report.

Device Story

PrimeLung is a software module for thoracic CT image analysis; operates on PC workstations with Windows OS. Inputs consist of thoracic CT datasets (helical, multidetector, or electron beam). Device provides tools for visualization (MIP, MPR, 3D volume rendering), segmentation of lung nodules, volume measurement, and nodule matching. Physician uses these tools to analyze lung regions and generate automated reports containing patient information, images, and clinical recommendations. Intended for clinical use to assist in diagnostic decision-making regarding lung nodules.

Clinical Evidence

Bench testing only. Testing verified all functional specifications, including GUI, measurement tools, segmentation tools, and report generation. Comparison tool testing demonstrated 100% matching accuracy on specified datasets.

Technological Characteristics

Software-based image analysis module for PC workstations running Windows. Supports helical, multidetector, and electron beam CT scanners. Features include MIP, MPR, 3D volume rendering, nodule segmentation, volume measurement, and automated report generation.

Indications for Use

Indicated for use by physicians to visualize and analyze thoracic CT datasets, including lung nodules and other lung parameters, and to generate automatic reports.

Regulatory Classification

Identification

A computed tomography x-ray system is a diagnostic x-ray system intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from the same axial plane taken at different angles. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.
