The summary describes standard image reconstruction and processing techniques (modified Feldkamp algorithm) and a DICOM viewer. There is no mention of AI, ML, or related terms.
No
The device is an imaging system used for diagnosis and planning (e.g., implant planning), not for delivering direct therapy.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device provides "planning and diagnostic support".
No
The device description clearly states that the system consists of a scanner and a software package, and lists multiple hardware components like the main affixed unit, overhead, gantry, tube head, X-ray source assembly, collimator, and receptor panel. While software is a crucial part of the system, it is not the only component.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is an x-ray system for providing images and volume reconstructions of the head area for "planning and diagnostic support". This involves imaging the patient directly, not analyzing samples taken from the patient.
- Device Description: The description details an X-ray imaging system with a scanner and software for image reconstruction and viewing. This is consistent with an in-vivo imaging device, not an in-vitro diagnostic device which would typically involve analyzing biological samples (blood, urine, tissue, etc.).
- Anatomical Site: The device is used on the "head area", which is a part of the living patient.
- Input Imaging Modality: The input is "X-ray", which is an imaging modality used on living subjects.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic purposes. This device operates by imaging the patient directly using X-rays.

Device Description
i-CAT FLX V series / KaVo 3D eXam+ V series manufactured by Imaging Sciences International, is a Cone Beam Volumetric Tomography and Panoramic X-ray dental imaging system that consists of a scanner and a software package for image reconstruction. The two models, i-CAT FLX / KaVo 3D eXam+, are of identical design in the i-CAT Scanner family. The components of the system include the main affixed unit, the overhead, the gantry, the tube head, the X-ray source assembly and collimator, the receptor panel, and software package for image reconstruction. The system is an open design that allows patients to sit upright during a procedure. An electric powered seat is built into the scanner for proper patient positioning. The V series refer to 3 different fieldof-view configurations (V8, V10, V17) available on each model based on licensing of the acquisition software.
The software package includes a device specific software package (SmartScan STUDIO) that is required to operate the i-CAT FLX System through a visual touchscreen interface and a post-processing imaging software. The modules within the device specific software perform the Image Acquisition, Quality Assurance, Device Calibration, and Image Reconstruction and Processing functionalities of the device. The software utilizes a modified Feldkamp algorithm for reconstruction. There is a basic DICOM viewer component (with limited image viewing capabilities) for the operator to ensure that the data collection and image processing are correct. Also provided with the device is a postprocessing imaging software, such as TxSTUDIO marketed under K123519. It is a volumetric imaging software designed specifically for dental clinicians, intended for use as a planning and simulation software in the placement of dental implants, orthodontics and surgical treatment. The imaging software reads DICOM data from dental CT machines, such as devices in the i-CAT family.
Cone Beam Volumetric Tomography is a medical imaging technique that uses X-rays to obtain cross-sectional images of the head or neck. The proposed device is a CBCT dental system with 2 modes of operation: panoramic and CBCT. The X-ray incident upon the receptor that generate sufficiently contrasted images. Quality of the images depends on the level and amount of X-ray energy delivered to the tissue. When interpreted by a trained physician, these images provide useful diagnostic information. The scanner has the ability to capture data for 3D skull reconstruction for the following procedures:
CBCT mode:
o Implants
TM Joints O
Reconstructed Panoramic o
Reconstructed Cephalometrics O
o Airway / Sinus, etc.
Nerve Canal o
Panoramic mode:
o PAN Conventional Digital Panoramic Feature
In addition, the user can choose to scan using the Standard protocol, the QuickScan protocol, or the QuickScan+ protocol. The user can choose to reduce the radiation exposure to patients by lowering the exposure time (from Standard to QuickScan), or by lowering all the loading factors (from Standard to QuickScan+). The radiation dose level, in the form of DAP value, is readily displayed on the protocol selection screen of the user interface so the user may make an informed choice.

*Receptor panels utilized in the proposed device has been previously cleared as a component of the device in K 133620.
As evidenced through the Design Verification and Validation, the proposed device can produce volumetric and panoramic images of the maxillofacial (including ENT) areas in the head, and they are of equivalent diagnostic quality as the predicate devices. The minor technological difference in the shape of image volumes does not affect imaging of the intended anatomical structures.
Based upon an analysis of the technological differences, and the substantiation through design verification and validation, ISI determines that the proposed i-CAT FLX / KaVo 3D eXam+ is substantially equivalent to the predicate devices, GALILEOS Comfort Plus (K123070) and i-CAT FLX (K133620), and does not raise any new concerns.

7. Non-Clinical Performance Data:
Performance bench testing was conducted as part of design control to ensure the substantial equivalence of i-CAT FLX/KaVo 3D eXam+ to the predicate devices. The substantial equivalence for the proposed indications for use is substantiated through verification and validation testing on two dimensional images and three dimensional volume reconstructions of the head area, which includes ENT and maxillofacial areas, for use in planning and diagnostic support in adult and pediatric care. The verification and validation activities for the software package also supports the substantial equivalence of the proposed device. Biocompatibility evaluation was conducted on patient contacting accessory parts and found to be in conformance with ISO 10993-5:2009 and ISO 10993-10:2010. EMC and Electrical Safety testing were performed by Intertek Testing Services and found to meet all the requirements in standards IEC 60601-1: 2005 (R)2012 (AAMI ES60601-1:2005/(R)2012), IEC 60601-1-6:2010, IEC 62366:2007/(R)2013, IEC 60601-2-63:2012, IEC 60601-1-3:2008, IEC 60601-1-2:2007, and IEC 60825-1:2007.
8. Clinical Performance Data:
Clinical images acquired using i-CAT FLX/KaVo 3D eXam+ were reviewed by qualified clinicians to be of acceptable clinical effectiveness for the proposed indications for use.
9. Conclusion as to Substantial Equivalence:
Based on the substantial equivalence comparison of intended use, design, technological characteristics, performance, labeling, biocompatibility, standards, and other characteristics, the minor differences between i-CAT FLX/KaVo 3D eXam+, and the predicate devices, GALILEOS Comfort Plus (K123070) and i-CAT FLX (K133620), do not raise new concerns for the proposed indications of use. Imaging Sciences International concludes that the proposed device is substantially equivalent to the predicate devices.
