Problem the AI is intended to solve

The O-arm O2 Imaging System is a mobile X-ray system designed for 2D and 3D imaging for adult and pediatric patients weighing 60lbs or greater and have an abdominal thickness greater than 16cm. It is intended to be used to benefit physicians with 2D and 3D information of anatomic structures and objects with high X-ray attenuation, such as bony anatomy and metallic objects.

Expected benefits

Supports X-ray workflows.

System outputs

Spine Smart Dose feature leverages Machine Learning technology with existing O-arm images to achieve a reduction in dose on the O-arm O2 Imaging System. It is an algorithm designed to reduce the noise of 3D reconstructions acquired from fewer acquisitions so that clinically viable 3D images can be produced using fewer projections.
