The summary describes standard image reconstruction and processing techniques for 3D imaging and fluoroscopy, with no mention of AI or ML.
No
The device is described as an "x-ray imaging device" used for diagnostic support, reconstructing images, and fluoroscopy during surgery. It does not provide any treatment or therapy.
Yes
The intended use explicitly states that the device is "for use in diagnostic support" and the device description notes that it "generates three-dimensional images that make possible precise diagnosis of the head and neck areas."
No
The device description clearly outlines significant hardware components including a C-arm assembly, x-ray head, image intensifier, control box, and patient chair. While it includes software, it is an integral part of a larger hardware system.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The 3D Accu-I-tomo is an x-ray imaging device. It acquires images of the head and neck areas directly from the patient's body using radiation. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states it's for acquiring images of the head and neck for diagnostic support and fluoroscopy during surgery. This involves imaging the patient directly, not analyzing in vitro samples.
The device falls under the category of medical imaging devices, specifically a type of X-ray system.

Intended Use / Indications for Use
The 3D Accu-I-tomo is an x-ray imaging device that acquires a 360 degree rotational sequence of the head and neck areas, including the ENT and dentomaxillofacial areas, for use in diagnostic support. The device accomplishes this task by reconstructing a three-dimensional matrix of the examined volume and producing two-dimensional views of this volume, displaying both two- and three-dimensional images. The device can also be used for fluoroscopy during surgery, mostly for ENT and TMJ applications and mostly with a contrast medium. The device is operated and used by physicians, dentists, and x-ray technologists.

Device Description
The 3D Accu-I-tomo is an x-ray imaging device that acquires a 360 degree rotational sequence of the head and neck areas, including the ENT and dentomaxillofacial areas, for use in diagnostic support. The device accomplishes this task by reconstructing a three-dimensional matrix of the examined volume and producing two-dimensional views of this volume, displaying both two- and three-dimensional images. The device can also be used for fluoroscopy during surgery, mostly for ENT and TMJ applications and mostly with a contrast medium. The C-arm assembly is mounted to the support column, which has an x-ray control panel for loading factors, an emergency stop switch, and a remote control for patient positioning. The C-arm assembly includes an image intensifier and an x-ray head with a beam-limiting device. The control box, which includes operational lights and an x-ray emission button, is typically placed in a separate room from the rest of the system. The patient chair includes an armrest and a headrest to fix the patient's head during the x-ray emission. An optional headrest for ENT applications is available which can be replaced with the headrest for dental applications. A Windows-based personal computer is connected to the 3D Accu-I-tomo, on which is installed "3DXD" driver software and "3DX Integrated Information System" application software. For the network environment, "3DXD" driver software and "3DX Integrated Information System" are installed in the server computer and "3DX Integrated Information System" is installed in the client computer. The Windows-based personal computer is not manufactured by J. Morita Manufacturing Corp. The 3D Accu-I-tomo operates in either CT mode or Fluoroscopic mode. In CT mode, it generates three-dimensional images that make possible precise diagnosis of the head and neck areas. It produces high resolution images and uses less x-radiation in comparison with conventional computed tomography x-ray systems. Fluoroscopy is available using the same x-ray head and image intensifier that are used for the CT mode. Fluoroscopy is mainly used with a contrast medium for ENT applications and surgery of the TM Joint. The same device can provide three-dimensional images and fluoroscopy. Both two- and three-dimensional images are taken for diagnosis before and after surgery. The fluoroscopic setting has three modes: a fluoroscopic moving image mode, a still image mode, and a testing mode. In the testing mode, it can take but not save a moving image.

The 3D Accu-I-tomo is substantially equivalent to the (i) Siemens Medical Systems' Siremobil C02 (K#973598), (ii), Siemens Siremobil Iso-C 3D Imaging Option (K#003266), and (iii) NIM s.r.l.'s NewTom Model QR-DVT 9000 (K#003787). The 3D Accu-I-tomo has similar general intended uses, principles of operation, and technological characteristics as the previously cleared predicate devices. Although there are minor difference in the characteristics of the 3D Accu-I-tomo and the predicate devices, these differences do not raise new questions of safety or efficacy.
The software used in the 3D Accu-I-tomo has been successfully validated by J. Morita Manufacturing Corp. The software validation report describes: the development process for the device's firmware; and driver software and application software installed in Windows-based personal computer; the software change control and code revision procedures; the system and software requirements; the software handling and storage procedures; a hazard analysis; and a software/firmware certification that the company followed the above-described procedures and policies.

The 3D Accu-I-tomo complies with the applicable thermal, mechanical, and electrical safety requirements of UL2601-1, IEC 60601-1, and its collateral standards and will comply with the applicable requirements of 21 CFR Subchapter J prior to marketing.
The 3D Accu-I-tomo uses biocompatible plastics on all body contacting surfaces. such as the head/chin band, headrest cushion, headrest support, side head support, subnasal point rest and ear piece, etc. Such plastics have been used in predicate devices or widely used in other medical applications in which the plastic is in contact with the patient's body.
