Overview

The O-arm™ O2 Imaging System by Medtronic Navigation is a mobile X-ray system designed for intraoperative 2D fluoroscopic and 3D imaging. It is intended for use with adult and pediatric patients weighing 60 pounds (27kg) or greater and having an abdominal thickness greater than 16 cm, where a physician benefits from detailed 2D and 3D information of anatomic structures, particularly bony anatomy and metallic objects. The system is compatible with certain image-guided surgery systems, offering real-time visualization to assist in surgical planning, validate accurate placement during procedures, and facilitate post-operative positioning evaluation.

Key advancements include O-arm™ 4.3 software, which introduces features like Medtronic Implant Resolution (MIR) for reducing metal artifacts around screws, and Spine Smart Dose (SSD), an AI-based algorithm that achieves dose savings up to 70% compared to standard scans while maintaining image quality. It also offers 3D Long Scan (3DLS) for imaging extended spinal segments.

What Physicians Need to Know

DICOM Support & Standards
The O-arm O2 Imaging System supports DICOM standards for image transfer, enabling seamless integration with hospital imaging infrastructure.
PACS Integration Method
Images from the O-arm O2 system are designed for seamless integration with surgical navigation systems like StealthStationu2122, which facilitates automatic data transfer of 2D and 3D images. This integration allows for efficient transfer of images within the OR workflow and potentially to PACS.
Reading Room Workflow Impact
The O-arm O2 primarily impacts the surgical workflow by providing intraoperative 2D and 3D imaging, potentially eliminating the need to send patients to radiology for pre-operative or intra-operative scans. This streamlines surgical planning and post-operative evaluation directly within the surgical suite.
AI Model Architecture (deep learning approach)
The O-arm O2 incorporates AI-based algorithms, specifically the 'Spine Smart Dose (SSD)' feature, which leverages Machine Learning technology to reduce radiation dose by approximately 70% compared to standard scans, while maintaining image quality. It achieves this by reconstructing clinically viable 3D images from fewer acquisitions. Additionally, Medtronic Implant Resolution (MIR) can reduce metal artifacts for selected Medtronic screws, enhancing visibility of bony anatomy.
Processing Speed (per study)
Standard 3D scans take 13 seconds for acquisition and an additional 13 seconds for processing and image reconstruction. High-definition 3D scans require 26 seconds for acquisition and 35 seconds for processing and reconstruction. The AI-based Spine Smart Dose (SSD) feature offers a faster 7-second scan time.
FDA Clearance Pathway (510k/De Novo)
The O-arm O2 Imaging System has received multiple FDA 510(k) clearances. The original O-arm was cleared in 2005, followed by the O-arm 1000 in 2009, and the O-arm O2 in 2015. Subsequent 510(k) clearances (e.g., K173664, K200074, K240465) cover software updates and new features, including the Spine Smart Dose. It is classified as a Class II device.
Supported Modalities
The O-arm O2 is a mobile X-ray system capable of both 2D fluoroscopic and 3D imaging. The 3D imaging provides CT-like data (cone-beam CT) intraoperatively. It is not an MRI or Ultrasound system but can be fused with pre-operative MRI and CT images for surgical navigation.
Physician Tip

Leverage the O-arm O2's intraoperative 2D/3D imaging capabilities to confirm implant placement and anatomical alignment in real-time, reducing the need for post-operative imaging and potential revisions. Utilize the AI-based Spine Smart Dose feature to minimize radiation exposure for both patients and staff without compromising image quality. Integrate seamlessly with surgical navigation systems for enhanced precision in complex spinal and cranial procedures. Consider its use for initial data acquisition in the OR to potentially eliminate the need for pre-op radiology scans, streamlining patient flow.

The O-arm O2 Imaging System is designed for seamless integration with Medtronic's StealthStationu2122 surgical navigation systems, enabling automatic data transfer and enhanced surgical guidance. Its DICOM compliance ensures compatibility with existing hospital PACS for image archiving and retrieval. The system's ability to fuse with pre-operative CT and MRI data further enhances its utility in comprehensive surgical planning.
