Yes
The device provides 2D and 3D imaging using X-rays to visualize complex anatomical structures, bones, joints, and fractures to assist physicians, which is a diagnostic purpose.
No
The device description explicitly details hardware components including a mobile C-arm with an X-ray tube, generator, and detector, and a monitor cart with displays and controls. It is a physical X-ray imaging system, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This testing is done outside of the body (in vitro).
- Device Function: The nView system 1 is an X-ray imaging system that visualizes human anatomy within the body (in vivo) using X-rays. It does not analyze specimens taken from the patient.
- Intended Use: The intended use clearly states it's for providing imaging of adult and pediatric populations during orthopedic surgical procedures to visualize anatomical structures.
Therefore, the nView system 1 falls under the category of medical imaging devices, not In Vitro Diagnostic devices.

Discussion of similarities and differences vs predicate
The subject device has an intended use that is a subset of the predicate device, Ziehm Vision RFD 3D (K142740). Both systems are intended to be used to generate fluoroscopic and tomographic images of human anatomy. The subject device's indications are a reduction of claims from the predicate (less clinical applications and smaller patient population) but are fully encompassed in the predicate indications. There are no new indications or claims for the subject device.
Intended Use
The intended use of the subject device and the predicate device are the same within the guidance of "The 510(k) Program: Evaluating Substantial Equivalence in Premarket Notifications [510(k)] Guidance for Industry and Food and Drug Administration Staff. Document issued on: July 28, 2014". Both systems are intended for 2D and 3D imaging of adult and pediatric populations. The subject device limits use in pediatric populations to patients over 6 years of age and imaged human anatomy up to 30 cm thickness. A reduction in patient population does not result in a new intended use. Both systems are indicated for orthopedic surgical procedures where the clinician benefits from 3D visualization of complex anatomical structures, such as those of high contrast objects, bones, joints, cervical, thoracic, and lumbar regions of the spine, and joint fractures of the upper and lower extremities. The predicate includes additional claims in the clinical procedures of cardiology, angiography, electrophysiology, urology, gastroenterology, etc. A reduction in the diseases a device is intended to treat do not result in a new intended use as they don't affect the safety and/or effectiveness of the new device.
Technological Characteristics
The technological characteristics governing how the device produces images of human anatomy are the equivalent in the subject device and the cleared Ziehm Vision RFD 3D (K142740) system. Both systems use X-ray to image the anatomy. Both systems are used for fluoroscopic and tomographic imaging.
The predicate displays 2D fluoroscopic views via real-time physical projection images. The subject device displays 2D fluoroscopic views via a digital projection through the 3D tomographic volume. Both systems result in 2D fluoroscopic projection views displayed to the user.
The predicate reconstructs 3D images from a series of X-ray images collected while the gantry is 001 S001 to K190064 nViewSystem1 Page 30
9
S001 to K190064 - Attachment 1 - Updated 510(k) summary moving around the patient. The subject device reconstructs tomographic images from a series of X-ray images collected while the gantry stays in a fixed position with respect to the patient, but while the X-ray tube rotates within the system. Therefore, motorized axes are not required as the gantry is stationary during acquisition. The predicate device reconstructs tomographic images from a series of X-ray images collected while the gantry rotates and shifts around the patient. Therefore, motorized axes were implemented to automatically move the gantry while acquisitions are occurring.
The Ziehm Vision RFD 3D (K142740) is based on a predicate limited angle device employing 135 degrees (+90 degrees and -45 degrees) of orbital rotation. The Ziehm Vision RFD 3D (K142740) employs a shift-scan-shift (SmartScan) motion of this predicate to increase relative coverage to 180 degrees. 3D images are generated from this shift-scan-shift dataset. The nView system 1 is a limited angle device utilizing a 117-degree multi-arc scan for 3D reconstruction. The images are acquired in two steps, first the gantry is rotated to +30 degrees, and images are collected as the tube rotates 360 degrees. Next, the gantry is rotated to -30 degrees, and images are collected as the tube rotates 360 degrees.
Both the subject device and the predicate device have a fluoroscopic mode. The predicate has a higher temporal resolution to allow for broader clinical applications such as interventional cardiology, hybrid procedures, and interventional angiography. For the clinical applications indicated for the subject device, "fluoro shots" are used in both the predicate and subject device. A temporal resolution of 0.5 fps is consistent with this clinical use.
Both the subject device and the predicate use a 30 cm CMOS detector. The subject device CMOS detector has a higher resolution but is used in a binned mode to be equivalent to the resolution of the predicate device detector. The subject device has a lower power x-ray tube with a fixed anode. A higher power x-ray tube with rotating anode is not required for the subject device with limitations on imaged anatomy thickness. The subject device is designed to operate at a lower radiation dose than the predicate.
The acquisition and reconstruction times for the subject device are faster than the predicate device. This allows the subject device to perform real-time fluoroscopic imaging via digital projections and faster 3D tomographic imaging and does not impact safety or efficacy of the device.
Summary of non-clinical test data
The demonstration of substantial equivalence is based on a comparison of features to the predicate device and on an assessment of non-clinical performance data.
The nView system 1 complies with the mandatory and voluntary standards listed in Table 3 below. The nView system 1 was developed in accordance with the FDA guidance documents listed in Table 4.

S001 to K190064 - Attachment 1 - Updated 510(k) summary issued on May 11, 2005 is also included as part of this submission. Non-clinical tests were conducted on the subject device during product development.
The risk analysis was completed and risk control implemented to mitigate identified hazards. The testing results support that all requirements have met the acceptance criteria. Testing for verification and validation for the device was found acceptable to support the claims of substantial equivalence.
The subject device was tested and found to be safe and effective for intended users, uses and use environments through the design control verification and validation process. The human factor usability validation showed that human factors are addressed in the system in simulated clinical use tests.
The subject device conforms to the cybersecurity requirements by implementing a process of preventing unauthorized access, modifications, misuse or denial of use, or unauthorized use of information that is stored, accessed or transferred from a medical device to an external recipient.
Additional engineering bench testing was performed including the clinical and non-clinical testing identified in the guidance for submission of 510(k) s for Solid State X-Ray Imaging Devices (SSXI); demonstration of system performance; and an imaging performance evaluation.
Conclusion as to substantial equivalence
In summary, the subject device has an intended use that is a subset of the predicate intended use and essentially the same technological characteristics as the predicate Ziehm Vision RFD 3D (K142740). Minor differences that do not impact the decision of substantial equivalency include: the subject device having lower temporal fluoroscopic views generated from tomographic reconstructions, a different acquisition geometry, a lower powered x-ray tube, and faster acquisition and reconstruction times. It has been demonstrated that the subject device has clinically acceptable performance per a qualified expert evaluation. The subject device does not have new functionalities when compared to the predicate device.
