What is O-arm in spinal surgery?
The O-armTM system is an intraoperative 2D/3D imaging system that is designed to meet the workflow demands of the surgical environment. It can be used in variety of procedures including spine, cranial, and orthopedics.
What is the difference between C arm and O-arm?
O-arm navigation system use is shorter in radiation time and larger in radiation exposure than C-arm fluoroscopy navigation system. However, the amount of the radiation exposure per unit time in O-arm navigation system is larger than in C-arm fluoroscopy navigation system.
Who invented the O-arm?
The O-arm Imaging System was created by Breakaway Imaging, and is marketed and distributed by Medtronic. The O-arm Imaging System received Food and Drug Administration clearance in 2005.
How does the Medtronic O-arm work?
The O-arm is a portable imaging device with a C-shaped arm that fits over the surgical table to take traditional two-dimensional X-ray images. During surgery it works like a CT scanner to take three-dimensional images in real time.
How much radiation does an O-arm give off?
The highest radiation values on patients in this study were measured with the O-arm. The O-arm exposed the highest radiation dose on the surgery field, where the scans are performed and significantly higher dose compared to fluoroscopy was reached (navigation: 43.2 ± 19.4 mSv; fluoroscopy: 27.7 ± 31.3 mSv; p = 0.02).
How much does an O-arm cost?
The O-arm integrates well with Stealth Navigation and costs A$850,000. Figures of the different 3D-fluoroscopy imaging systems are provided in Figure 1. 3D fluoroscopy imaging systems.
Are orthopedic surgeons exposed to radiation?
Orthopaedic surgeons and staff are exposed to ionising radiation during a variety of procedures. In general, orthopaedic staff are exposed to both direct and scattered radiation during procedures. Over the past few decades, orthopaedic surgery procedures using fluoroscopy screening has increased [1–5].
Are surgeons exposed to radiation?
Increased use of intraoperative fluoroscopy exposes the surgeon to significant amounts of radiation. The average yearly exposure of the public to ionizing radiation is 360 millirems (mrem), of which 300 mrem is from background radiation and 60 mrem from diagnostic radiographs.
Is the O-arm a CT?
