#### Device Description:
The OEC One ASD is a mobile C-arm X-ray system to provide fluoroscopic images of the patient during diagnostic, interventional, and surgical procedures such as orthopedic, gastrointestinal, endoscopic, urologic, neurologic, vascular, critical care, and emergency procedures. These images help the physician visualize the patient's anatomy and localize clinical regions of interest. The system consists of a mobile stand with an articulating arm attached to it to support an image display monitor (widescreen monitor) and a TechView tablet, and a "C" shaped apparatus that has a flat panel detector on the top of the C-arm and the X-ray Source assembly at the opposite end.
The OEC One ASD is capable of performing linear motions (vertical, horizontal) and rotational motions (orbital, lateral, wig-wag) that allows the user to position the X-ray image chain at various angles and distances with respect to the patient anatomy to be imaged. The C- arm is mechanically balanced allowing for ease of movement and capable of being "locked" in place using a manually activated lock.
The subject device is labelled as OEC One ASD.
The purpose of this premarket notification is to demonstrate that the subject device, OEC One ASD, is a modification of and is substantially equivalent to the predicate device OEC One (K182626).
#### Proposed Device Modification:
The modified OEC One ASD employs the same fundamental scientific technology as that of the unmodified predicate device (K182626). The primary change for the subject device is to introduce an amorphous silicon (a-Si) flat panel detector as the image receptor. Roadmap functionality, which is optional in the predicate device (K182626), has been removed and a printer shelf has been integrated into the subject device to place the applicable printer on.

# Indications for Use:
The OEC One ASD mobile C-arm system is designed to provide fluoroscopic and digital spot images of adult and pediatric patient populations during diagnostic, interventional, and surgical procedures. Examples of a clinical application may include: orthopedic, gastrointestinal, endoscopic, urologic, neurologic, vascular, critical care, and emergency procedures.
The intended use and indications for use are unchanged from the predicate device.
# Technology:
The indications for use are identical and the technology is similar to the predicate device.
The primary change on the subject device is to introduce an Amorphous Silicon (a-Si) solid state flat panel X-ray detector. A printer shelf is integrated into the subject device for the user to place the applicable printer on. The electrical boards have been re-laid out or redesigned to be more compact to make space for the printer shelf. The image shape changed from a circle to a squircle by introducing the flat panel detector and squircle secondary collimator. The X-Ray source monoblock remains unchanged from that of the predicate device OEC One (K182626). The hardware changes also include using an up-to-date computer, tablet and monitor that offers more image storage, processing speed, and higher resolution display, driven by IT technology advancement.
Its software is based on the architecture, design and code base of the predicate device OEC One (K182626). The software architecture framework was updated to a platform-based architecture with no significant changes in order to support different OEC C-Arm products. The modifications were also being made to support the flat panel detector, the necessary imaging and post-processing applications related to the flat panel detector, and device specific features/functionality. The design followed the same design control process and software development lifecycle process that is compliant to IEC 62304 used in the predicate OEC One.
The table below compares the main performance data of the proposed device with the predicate device.
