#### 13. DEVICE DESCRIPTION:

Aquilion Exceed LB (TSX-202A/3) V10.6 with AiCE-i (Advanced intelligent Clear-IQ Engineintegrated) is a whole body multi-slice helical CT scanner, consisting of a gantry, couch and a console used for data processing and display. This device captures cross sectional volume data sets used to perform specialized studies, using indicated software, 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 methods. These 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. The AiCE algorithm has not been modified or retrained since the previous clearance in the predicate, K192832.

#### 14. INDICATIONS FOR USE:

This device is indicated to acquire and display cross-sectional volumes of the whole body, to include the head. The Aquilion Exceed LB has the capability to provide volume sets. These volume sets can be used to perform specialized studies, using indicated software/hardware, by a trained and qualified physician.

AiCE (Advanced Intelligent Clear-IQ Engine) is a noise reduction algorithm that improves image quality and reduces image noise by employing Deep Convolutional Network methods for abdomen, pelvis, lung, extremities, head and inner ear applications.

#### 17. TESTING

Risk analysis and verification/validation activities conducted through bench testing demonstrate that the established specifications for the device have been met. These studies compared both FBP and AiCE reconstructions in the predicate and subject devices.

### Performance Testing - Bench

# 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), Standard Deviation of Noise (SD) and Noise Power Spectra (NPS). It was concluded that the Aquilion Exceed LB system demonstrated substantially equivalent or improved performance relative to the predicate device as demonstrated by the results of the above testing.

# Dose Reduction with AiCE

A phantom study was conducted using the MITA-FDA LCD Body phantom and the results demonstrated a dose reduction of up 82% for AiCE Abdomen, relative to FBP.

# Quantitative Spatial Resolution

A comparison study was conducted, utilizing phantoms, in order to support a quantitative spatial resolution improvement claim of improved high contrast spatial resolution and simultaneous 50% noise reduction with AiCE Body STD.

### Noise Texture

An analysis of the NPS and kurtosis values for FBP, FIRST and AiCE was conducted and the results of the study support the following claim, noise appearance/texture is more similar to high dose filtered backprojection, compared to MBIR.

### Quantitative Body LCD and Noise Improvement

A phantom study was conducted using the MITA-FDA LCD Body phantom and the results demonstrated 1) 63% improved low contrast detectability and noise reduction of 57.8% with AIDR at the same dose for body compared to FBP and 2) 87% improved low contrast detectability and noise reduction of 67.2% with AiCE at the same dose for body compared to FBP.

# PUREViSION Optics

Phantom studies were conducted using the MITA-FDA LCD Body phantom and the results demonstrated 22% improved in low-contrast detectability and dose reduction of 27.5% at the same dose for Body CT and improved low contrast detectability at the same dose for Brain CT.

Representative clinical images were not necessary to demonstrate substantial equivalence of the subject device.
