DELTAVIEW MODEL
Overview
The DELTAVIEW MODEL, originally developed by Riverain Medical Group (now Riverain Technologies), was an early AI-driven medical imaging software. It was specifically designed for the temporal comparison of current and prior chest X-ray images to aid in the detection of subtle changes, such as emerging or enlarging lung nodules that may indicate early-stage lung cancer. The software utilized bone suppression technology to provide a clearer view of soft tissues by electronically removing ribs and clavicles from the radiograph. By aligning and registering two patient images, DELTAVIEW produced a third subtraction image, accentuating differences and making changes more conspicuous for radiologists. This technology was a precursor to Riverain Technologies’ current ClearRead™ suite, which continues to leverage advanced AI and patented suppression technologies to improve diagnostic accuracy and efficiency in cardiothoracic imaging.

What Physicians Need to Know
When using DELTAVIEW MODEL, pay close attention to the generated 'difference image' as it can reveal subtle interval changes in lung nodules that might be missed on standard side-by-side comparisons. Leverage the bone and vessel suppression features to obtain an unimpaired view of the lung parenchyma. Utilize the customizable reporting options to streamline documentation and ensure consistency with institutional guidelines (e.g., Fleischner and Lung-RADS scoring). Consider integrating this tool into your lung cancer screening programs and for routine follow-up of known pulmonary nodules to enhance detection accuracy and reading efficiency.
The DELTAVIEW MODEL and the broader ClearRead suite are designed for seamless integration into existing radiology workflows. They produce DICOM-compliant images that easily interface with any PACS system, appearing as an additional series in the patient study. The solutions are flexible, supporting deployment on various infrastructures including stand-alone servers, virtual machines, or cloud environments. Furthermore, they are compatible with CT scanners from diverse manufacturers and can integrate with advanced AI platforms like Aidoc's aiOSu2122 to further enhance workflow and insights.
