Yes
The device description explicitly mentions "AiCE (Advanced intelligent Clear-IQ Engine)" which utilizes "Deep Convolutional Neural Network methods" for image reconstruction and noise reduction. Deep Convolutional Neural Networks are a type of Artificial Intelligence/Machine Learning.
No
The device is a CT scanner, which is used for diagnostic imaging, not therapeutic purposes.
Yes
Explanation: The device is a CT scanner, which acquires and displays cross-sectional volumes of the body for "specialized studies" by "a trained and qualified physician," indicating its use in diagnosing medical conditions. The performance studies also mention "diagnostic quality" images.
No
The device description explicitly states that the Aquilion Precision is a "whole body multi-slice helical CT scanner, consisting of a gantry, couch and a console used for data processing and display." This indicates it is a hardware device with integrated software, not a software-only medical device. While it includes software components like FIRST 3.0 and AiCE, these are part of a larger hardware system.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
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 diagnostic purposes.
- Device Function: The description clearly states that this device is a CT scanner. It acquires and displays cross-sectional volumes of the whole body using X-rays. It processes and reconstructs these images.
- Lack of Specimen Handling: There is no mention of collecting, preparing, or examining specimens from the human body. The device works by scanning the patient directly.
While the device is used for diagnostic purposes (acquiring images for a physician to interpret), it does not fit the definition of an In Vitro Diagnostic device. It is an in vivo imaging device.
No
The letter does not explicitly state that the FDA has reviewed, approved, or cleared a PCCP for this specific device. The relevant text for PCCP is "Not Found."
Intended Use / Indications for Use
This device is indicated to acquire and display cross-sectional volumes of the whole body, to include the head. The Aquilion Precision 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.
FIRST 3.0 is an iterative reconstruction algorithm intended to reduce exposure dose and improve high contrast spatial resolution for abdomen, pelvis, chest, cardiac, extremities and head applications.
AiCE is a noise reduction algorithm that improves image quality and reduces image noise by employing Deep Convolutional Neural Network methods for abdomen and pelvis applications.

Device Description
Aquilion Precision (TSX-304A/1 and /2) V8.8 with AiCE is an ultra-high resolution whole body multi-slice helical CT scanner, consisting of a gantry, couch and a console used for data processing and display. Aquilion Precision incorporates a 160-row, 0.25 mm detector, a 5.7-MHU large-capacity tube, and 0.35 s scanning, enabling wide-range scanning with short scan times to capture cross sectional volume data sets used to perform specialized studies, using indicated software/hardware, by a trained and qualified physician. In addition, the subject device incorporates the latest reconstruction technology, AiCE (Advanced intelligent Clear-IQ Engine), intended to reduce image noise and improve image quality by utilizing Deep Convolutional Neural Network methods to 1024x1024 HR/SHR images. 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.

Summary of Performance Studies
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, Modulation Transfer Function (MTF)-Edge, Standard Deviation of Noise (SD), Noise Power Spectra (NPS), Low Contrast Detectability (LCD) and Pediatric water phantom.
Low Contrast Detectability, Noise Reduction, Dose Neutrality:
AiCE demonstrated 13% improved low contrast detectability and 42% noise reduction for superhigh resolution body at the same dose compared to AIDR 3D. Additionally, it was demonstrated that there is dose neutrality between super-high resolution mode with AiCE and normal resolution mode with AIDR as well as superior LCD performance for super-high resolution body at the same dose for AiCE vs AIDR 3D.
Spatial Resolution:
A spatial resolution comparison study was conducted to support a high contrast spatial resolution improvement claim of 8.8 lp/cm at 10% of the MTF for AiCE relative to AIDR 3D Standard for abdomen/body.
Representative abdomen/pelvis diagnostic images, reviewed by an American Board Certified Radiologist, were obtained using the subject device and it was confirmed that the AiCE reconstructed images were of diagnostic quality.
