RadioLens v1.0 software is a medical diagnostic application that displays, processes, stores, and transfers DICOM data, with the exception of mammography. It provides the capability to store images and patient information, perform filtering, digital manipulation, and quantitative measurements. The client software is designed to run on standard personal and business computers.

RadioLens v1.0 includes an optional SpindleX module which is used to analyze potential vertebral body displacements in spine, either absolute or relative, using cervical/lumbar digital X-Rays of spine. A qualified medical practitioner may use the module to semi-automatically identify relevant spine anatomy and calculate vertebral displacement measurements. Measurements are then used to determine severity and location of any spinal ligament injury leading to subluxation using criteria published in AMA Guides to The Evaluation of Permanent Impairment, 5th & 6th edition.

SpindleX is meant for assistance with analysis of spinal ligament injury in the adult population (>18 years of age) as captured in stress x-rays. SpindleX is not meant for patients that have undergone surgery or other traumatic injury that result in distortion of spinal anatomy.

Indications for use as stated in the FDA summary.
