The summary describes standard image reconstruction and processing techniques for a CBCT system and does not mention any AI or ML capabilities.
No
Explanation: The device is an x-ray imaging system used for diagnostic support by acquiring and displaying images for review, not for treating any condition.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the device is "for use in diagnostic support," and the "Device Description" section reiterates that it is "intended for diagnostic use."
No
The device description explicitly states that the NewTom 5G XL consists of three main components: the scanner unit, the motorized patient support, and the main workstation. This indicates it is a hardware system with integrated software, not a software-only device.
Based on the provided information, the NewTom 5G XL is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- NewTom 5G XL Function: The NewTom 5G XL is an imaging system that uses X-rays to create images of the internal structures of the human body. It does not analyze specimens taken from the body.
- Intended Use: The intended use clearly states it's for acquiring images of the head, neck, and extremities for use in diagnostic support. This involves visualizing internal anatomy, not analyzing biological samples.
- Device Description: The description reinforces that it's a volumetric Cone Beam Computed Tomography (CBCT) system that obtains geometrical and x-ray information through digital images.
Therefore, the NewTom 5G XL falls under the category of a medical imaging device, not an In Vitro Diagnostic device.

Device Description
The NewTom 5G XL is a volumetric Cone Beam Computed Tomography (CBCT) system intended for diagnostic use. It obtains geometrical and x-ray information through digital 2D and 3D images of the objects in the area being examined.
The NewTom 5G XL is able to analyze the regions of the head, including the dental and maxillofacial and the otorhinolaryngology areas, the cervical spinal column and upper and lower limbs.
Particularly, the NewTom 5G XL can be used in the following fields:
- maxillofacial surgery, orthodontics, implants, endodontics, otorhinolaryngology, prosthetics, and orthopedics.
The NewTom 5G XL CBCT device acquires a sequence of x-ray images by performing a rotation around the patient's head then, starting from these images, reconstructs a 3D matrix of the examined volume and produces 2D views of it.
From these views it is possible to reconstruct other 2D images on which 3D images, angle and distance measurements can be taken. Each image can be printed and/or stored in a magnetic/optical media (CD, hard disk, network, USB pen or other mass storage device).
NewTom 5G XL consists of three main components: the scanner unit, the motorized patient support and the main workstation (secondary workstations could be also available as optional) that supports the dedicated software, enabling data acquisition.
The software requires a Microsoft Windows OS (version 7 or later).
NewTom 5G XL is intended for all people who usually undergo radio-diagnostic examinations like the ones performed by this device, in compliance with the use instructions, the medical praxis and the local regulations.

4. Device Description
The NewTom 5G XL is a volumetric Cone Beam Computed Tomography (CBCT) system intended for diagnostic use. It obtains geometrical and x-ray information through digital 2D and 3D images of the objects in the area being examined.
The NewTom 5G XL is able to analyze the regions of the head, including the dental and maxillofacial and the otorhinolaryngology areas, the cervical spinal column and upper and lower limbs.
Particularly, the NewTom 5G XL can be used in the following fields:
- maxillofacial surgery, orthodontics, implants, endodontics, otorhinolaryngology, prosthetics, and orthopedics.
The NewTom 5G XL CBCT device acquires a sequence of x-ray images by performing a rotation around the patient's head then, starting from these images, reconstructs a 3D matrix of the examined volume and produces 2D views of it.
From these views it is possible to reconstruct other 2D images on which 3D images, angle and distance measurements can be taken. Each image can be printed and/or stored in a magnetic/optical media (CD, hard disk, network, USB pen or other mass storage device).
NewTom 5G XL consists of three main components: the scanner unit, the motorized patient support and the main workstation (secondary workstations could be also available as optional) that supports the dedicated software, enabling data acquisition.
The software requires a Microsoft Windows OS (version 7 or later).
NewTom 5G XL is intended for all people who usually undergo radio-diagnostic examinations like the ones performed by this device, in compliance with the use instructions, the medical praxis and the local regulations.
NewTom 5G XL has been specially designed for patients from 3 years of age [87 cm (34.25 in) standing height] to the 99th percentile of the U.S. adult male chart [193.92 cm (76.35 inches)
5
standing height]. The device may also be used for pediatric or small patients. The features available for this purpose are:
- o automatic calculation of minimum X-ray parameters required to carry out an examination, according to the size and the density of the volume to be examined;
- o indication of the values of the dose administered during the examination, before the actual scanning;
- necessity of carrying out examinations with the patient seated or lying on the patient table, thus reducing the risk of movement;
- . availability of adjustable fixing and centering tools, to secure the patient's head and/or limbs and allow a correct positioning;
- . possibility of using fields of view with reduced dimensions, such as: 6x6 (6 cm volume diameter, 6 cm height), 8x6, 8x8. Possibility of scanning in Eco Scan mode, a low-dose protocol characterised by reduced scanning time.
Studies have shown that pediatric patients may be more radiosensitive than adults (i.e., the cancer risk per unit dose of ionizing radiation is higher), and so unnecessary radiation exposure is of particular concern for pediatric patients. For this reason detailed information are reported on the user manual in order to safeguard children and small-sized patient, particularly recommending the use of the Eco Scan mode, a low-dose protocol characterized by reduced scanning time.
The device must be managed and used by doctors, dentists, radiologists and other legally qualified professionals.
5. Indications for Use
The NewTom 5G XL is a cone beam computed tomography (CBCT) X-Ray Imaging System that acquires sequences of images of the head, including ear, nose and throat (ENT), of dentomaxillofacial complex, teeth, mandible and jaw, temporomandibular joint (TMJ), other areas of the human skull and neck with sections of upper cervical spine, and upper and lower extremities for use in diagnostic support.
The device accomplishes this task by reconstructing a 3D matrix of the examined volume and producing two-dimensional views of this volume, displaying both two and three dimensional images.
The device is operated and used by physicians, dentists, x-ray technologists and other legally qualified professionals.
6. Comparison of technological characteristics with the predicate device
NewTom 5G XL Computed tomography x-ray system manufactured by CEFLA s.c. is substantially equivalent to the following devices legally marketed in the US:
| Device | Applicant [Note] | Device Name | Pre-market notification
Number | Product code |
|---------------------|------------------|----------------|-----------------------------------|--------------|
| Predicate
device | QR s.r.l. | NewTom 5G | K142222 | JAK, OAS |
| Reference
device | QR s.r.l. | NewTom VGi Evo | K151612 | OAS |
The NewTom 5G XL device is a variant of the Predicate device NewTom 5G (cleared K142222). Compared to this version, NewTom 5G XL features some changes concerning the power
6
supply, the image acquisition panel, the x-ray tube, the software revision, the electronic boards revision and aesthetic changes to the cover.
The software of proposed NewTom 5G XL is substantially equivalent to the NewTom 5G computed tomography x-ray system already cleared and described in the submission NewTom 5G K142222. The functionalities of the proposed device NewTom 5G XL were already included in the previous version of the software already approved (K142222). The major changes introduced starting from the previous system can be summarized as follows:
| Scan
modes: | Additional Field of Views (as detailed in the table below)
Different ranges of selectable Exposure time - Scan time (as detailed in the
table below) |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| User
interface: | New tools for 2D and 3D image management and visualization: additional
grid, show/hide overlays, popup of information, extended implants library,
multiple image rotation. |
| | Introduction of specific application modes that are different combinations of
software tools and functions available in the NNT workspace. Application
modes: Oral & Maxillo facial surgery, Medical Specialties, ENT specialties,
Imaging Center. |
| | Update the software GUI: colors, icons, buttons size. |
| | Added patient dose verification tool (dose book). |
For CBCT image acquisition and 3D processing (also referred to as "3D mode"), panoramic x-ray exposures (also referred to as "2D mode") and mechanical construction, the subject NewTom 5G XL, provides similar characteristic, operating principles and components adopted in Predicate device NewTom 5G (K142222). NewTom 5G XL allows 3D images having a detected area bigger than the one granted by NewTom 5G.
On the other hand, the subject device NewTom 5G XL version, presents similarity to the cleared reference device NewTom VGi Evo (K151612) because it uses the same 3D image area detector, while it differs due to the mechanical construction.
Therefore, as it appears from the comparison table here below reported, considering the intended use, the characteristics of the predicate devices K142222 and of the reference device K151612 and the results of functional and security test performed, the subject device NewTom 5G XL may be found substantially equivalent to the cleared predicate and reference device.

- IEC 62366
- IEC 60601-2-28
- IEC 60601-2-44
- IEC 62304
- 21 CFR 1010.3
- 21 CFR 1020.30
- 21 CFR 1020.33
In particular, IEC 60601-2-44 "Particular requirements for the basic safety and essential performance of X-ray equipment for computed tomography" has been applied with the main exclusions of Sensitivity profile statement, Geometric efficiency in the Z direction and the 21 CFR 1020.33 "Performance standards for ionizing emitting products, Computed tomography (CT) equipment" has been applied with the main exclusions of Sensitivity profile statement, control of xray emission with a shutter, scan increment accuracy.
The exclusions are based on the principles of operation CBCT (Cone Beam Computed Tomography) technology that allows the user to obtain all the necessary data for the volumetric reconstruction of the examined area through one complete rotation of the X-ray generator and detector around the patient's head, neck and limbs. The device doesn't use a shutter to control the x-ray emission. The patient support is fixed during the X-ray emission.
Non-clinical performance tests

H. Evaluation of Cone Beam CT Image Quality by the NewTom 5G XL On the subject device have been performed clinical evaluation in order to judge the images resolution and quality during CBCT acquisition. The quality evaluation has been done considering different anatomical sites and different patient population. Based on clinical experience, the test results can show the diagnostic reliability and utility of the radiographic images produced by the NewTom 5G XL CBCT scanner.
All above mentioned tests (Safety and EMC / Non clinical / Clinical) allow to demonstrate that: -
o images produced by NewTom 5G XL have performances that can be compared to the ones given by the predicate device and by the reference device;
-
The image quality performances are able to fulfill the main standard reference which can be ● considered to evaluate and qualify a CBCT device.
For these reasons the results of the non-clinical performance, together with the clinical evaluation of the NewTom 5GXL images quality, allow to demonstrate the substantial equivalence of the NewTom 5G XL to the predicate device and to the reference device. .
