Micro C brings x-ray to the point of care, enabling medical imaging with clarity, safety, accuracy, and speed. Every OXOS device connects to our leading radiographic imaging platform, allowing seamless image management and knowledge sharing while simultaneously distributing teleradiology and radiographic artificial intelligence at scale.

OXOS innovations in fundamental x-ray technology brings high quality, safe, dynamic radiographic imaging out of the rad suite directly to the point of care”.

OXOS Medical, Inc. was founded in May of 2016 to develop and commercialize the world’s first handheld dynamic digital radiography device for orthopedic surgery. Devised by Dr. Greg Kolovich, a Harvard-trained, board-certified orthopedic surgeon, the device is designed to address a number of shortcomings of the traditional C-Arm.

While designing and developing the Micro C, it became apparent that the advantages of the device translated into a huge number of adjacent care scenarios. By leveraging the sensor stack of the device, combined with the cloud connected platform, OXOS is able to bring radiographic diagnostics to the point of care. The Micro C is a safe, fast and accurate imaging device and enables x-ray imaging at the point of care.
