## 12. DEVICE DESCRIPTION:
Aquilion Lightning (TSX-036A/7) V10.2 with AiCE-i. The Aquilion Lightning (TSX-036A/7) V10.2 with AiCE-i is an 80-row CT system that is a whole body, multi-slice helical CT scanner, consisting of a gantry, couch and console used for data processing and display. This device captures cross sectional volume data sets used to perform specialized studies, using indicated software/hardware, by a trained and qualified physician. This system is based upon the technology and materials of previously marketed Canon CT systems. In addition, the subject device incorporates the latest reconstruction technology, AiCE-i (Advanced intelligent Clear-IQ Engine - integrated), intended to reduce image noise and improve image quality by utilizing Deep Convolutional Network (DCNN) methods. This reconstruction algorithm is predicated on AiCE reconstruction algorithm previously 510(k) cleared per K192832 on the Canon CT scanner Aquilion Prime SP (TSX-303B/8) V10.2 with AiCE-i, which serves as a reference predicate for this submission. The DCNN methods can more fully explore the statistical properties of the signal and noise. By learning to differentiate structure from noise, the algorithm produces fast, high quality CT reconstruction for every patient.
#### 13. INDICATIONS FOR USE:

{6}------------------------------------------------
This device conforms to applicable Performance Standards for Ionizing Radiation Emitting Products [21 CFR, Subchapter J, Part 1020]
#### 16. TESTING
Risk analysis and verification/validation activities conducted through bench testing demonstrate that the established specifications for the device have been met.
## Image Quality Evaluation
CT image quality metrics were performed, utilizing phantoms, to assess Contrast-to-Noise Ratios (CNR), CT Number Accuracy, Uniformity, Slice Sensitivity Profile (SSP), Modulation Transfer Function (MTF)-Wire, Standard Deviation of Noise (SD), Noise Power Spectra (NPS), Low Contrast Detectability (LCD). It was concluded that the AiCE-i images are substantially equivalent to the predicate device as demonstrated by the results of the above testing.
#### Quantitative Spatial Resolution
A phantom study was conducted to compare spatial resolution performance between AiCE, filtered backprojection and AIDR 3D. It was determined that there is double the high contrast spatial resolution versus AIDR 3D for body (AiCE Body Sharp).
#### Quantitative Body LCD, Noise Improvement and Dose Reduction
A dose reduction study was conducted using AiCE and based on the results, a dose reduction claim of up to 82.9%, relative to FBP, is supported as well as 15% improved low contrast detectability and noise reduction of 29% at the same dose for body compared to AIDR 3D.
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 included as part of this submission. This documentation includes justification for the Moderate Level of Concern determination as well as testing which demonstrates that the verification and validation requirements for the modifications described above have been met.
It was determined that representative clinical images were not necessary to demonstrate substantial equivalence of the subject device.
Cybersecurity documentation, per the FDA cybersecurity premarket guidance document "Content of Premarket Submissions for Management of Cybersecurity in Medical Devices" issued on October 2, 2014, is also included as part of this submission.
