No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and describes image processing techniques like AIDR 3D and SEMAR, which are typically traditional algorithms, not necessarily AI/ML.
No
The device is described as an 80-row CT System intended to acquire and display cross-sectional volumes of the whole body, which indicates it is a diagnostic imaging device, not a therapeutic one.
Yes
The device produces "diagnostic images" and is intended to be used by a "trained and qualified physician" for "specialized studies," indicating its role in diagnosis rather than treatment or prevention.
No
The device description explicitly states it is an "80-row CT System," which is a hardware device. While it includes software components for image acquisition and processing, it is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Aquilion Lightning is a CT system. Its primary function is to acquire and display cross-sectional images of the whole body using X-rays. It does not perform tests on biological samples.
- Intended Use: The intended use is to "acquire and display cross-sectional volumes of the whole body." This is an imaging function, not an in vitro diagnostic test.
- Device Description: The description confirms it's a CT system based on X-ray technology.
- Input Imaging Modality: It explicitly states "Computed Tomography X-ray System."
The device is a medical imaging device used for diagnostic purposes, but it falls under the category of imaging systems, not in vitro diagnostics.

Summary of Performance Studies
Risk analysis and verification/validation testing conducted through bench testing are included in this submission which demonstrates that the established specifications for the device have been met. CT image quality metrics were performed, utilizing phantoms, which demonstrated that the subject device is substantially equivalent to the predicate device with regard to spatial resolution, CT number magnitude and uniformity, noise properties, low contrast detectability and CNR performance.
Representative diagnostic images, reviewed by an American Board Certified Radiologist, including head, chest, abdomen, pelvis and peripheral exams were also obtained using the subject device which demonstrates that the device produces images of diagnostic quality and; therefore, performs as intended.
Software Documentation for a Moderate Level of Concern, per the FDA guidance document, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices Document" issued on May 11, 2005, is also included as part of this submission.
Additionally, testing of the subject device was conducted in accordance with the applicable standards published by the International Electrotechnical Commission (IEC) for Medical Devices and CT Systems.

Dear Mr. Tadeo:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
