O arm imaging system

Manufactured by Medtronic

Sourced in United States

The O-arm™ imaging system is a mobile, multipurpose imaging device that provides real-time, intraoperative, 2D and 3D imaging for a variety of surgical procedures. The system is designed to capture high-quality images to assist surgeons during operations.

Studies were performed on the imaging bench shown in Figure 1, incorporating a rotating anode
radiography/fluoroscopy x-ray tube (RAD-94). The system geometry emulated
that of an interventional imaging system (e.g., C-arm or O-arm) with a
source-to-detector distance of 116.8 cm and source-axis distance of 64.8 cm
(matching the basic geometry of the O-arm^™ imaging system;
Medtronic, Littleton MA, USA). CBCT scans involved 720 projections acquired
over 360° with synchronized x-ray pulses and
“step-and-shoot” rotation, thus eliminating effects of
azimuthal blur.^{25 (link)} Neither
an antiscatter grid nor a bowtie filter was used in the current studies in
order to focus on more basic (raw) characteristics of FPD performance.
Unless otherwise specified, readout rate was fixed at 5 frames per second
(fps) for 2D fluoroscopy and 4 fps for 3D CBCT to accommodate the lower
frame rate of the reference

mode on the a-Si:H FPD.

The study methodology is divided into five sections. The first section briefly describes the study design. The second section describes the collection of data using the StealthStation and O-arm imaging system (O-arm Surgical Imaging, Medtronic Inc., Dublin, IE) for both manual and power procedures. These systems are used for all patients throughout this study and use intraoperative 3D scans and optical tracking to provide pseudo-real-time feedback to the surgeon with regard to tool position relative to patient anatomy. The third section describes the postprocessing steps that were taken after the procedure to determine the final screw placement. Finally, the last two sections detail the two metrics used to assess procedure performance: angular deviation and reference point deviation. All research was conducted in accordance with a test protocol approved by the University of Colorado Anschutz Medical Campus's Institutional Review Board (COMIRB Protocol 11-0990).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
