No
The document describes an iterative reconstruction algorithm (FIRST 1.0) which is a common image processing technique in CT, but it does not mention or provide evidence of AI/ML components like training data, test data, or specific AI/ML model types (DNN, etc.).
No
The device is indicated to acquire and display cross sectional volumes for diagnostic purposes, not for treating a disease or condition.
Yes
This device is a multi-slice helical CT scanner that acquires and displays cross-sectional volumes of the body and organs. The "Intended Use / Indications for Use" section states that the "volume sets can be used to perform specialized studies, using indicated software, of the whole organ by a trained and qualified physician" and the "Mentions image processing" section explicitly states that the device produces "images of diagnostic quality". These functions indicate that the device is intended to assist in the diagnosis of medical conditions.
No
The device description explicitly states that the device consists of a gantry, couch, and console, which are hardware components of a CT scanner. While it includes software (FIRST 1.0), it is not solely software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens from the human body. The intended use and device description clearly state that this device is a CT scanner used to acquire images of the human body in vivo (within the living body). It does not analyze biological samples like blood, urine, or tissue outside of the body.
- The device description focuses on imaging technology and image processing. The details provided describe the physical components of the CT scanner, how it acquires images using X-rays, and how those images are processed and displayed. This is characteristic of an imaging device, not an IVD.
- The performance studies described involve phantoms and in vivo imaging. The studies mentioned evaluate image quality metrics using phantoms and review diagnostic images obtained from patients. This is consistent with the testing of an imaging device.
Therefore, the Aquilion ONE Vision with FIRST 1.0 is a medical imaging device, specifically a CT scanner, and not an In Vitro Diagnostic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Image Quality Evaluation
CT image quality metrics were performed, utilizing phantoms, which demonstrated that the subject device is substantially equivalent to or demonstrates an improvement to the predicate device with regard to spatial resolution, CT number accuracy, contrast-to-noise ratio, noise properties, uniformity, slice sensitivity profile, low contrast detectability and standard deviation of noise. Studies were also conducted to demonstrate equivalence and/or improvements in CT number accuracy in water phantoms and artifact reduction using body phantoms.
Quantitative Dose Reduction Evaluation
The subject device demonstrated a dose reduction claim of up to 82.2% compared to filtered back projection as demonstrated by a model observer evaluation which showed that equivalent low contrast detectability to FBP (range from 0.6 - 0.686) can be achieved with 51.7% to 82.2% less dose using FIRST1.0 at Standard setting for thin (0.5 mm) reconstruction slice thickness in simulated body phantom (MITA-FDA phantom with a body ellipse surrounding it).
Artifact Reduction
For truncation artifacts, a body phantom was scanned at 25/50/150 mA and 80/160/320 rows and FIRST reconstruction was performed. It was confirmed that the image SD values in the shoulders have been improved and streak artifacts have been visually reduced, as compared with AIDR 3D. For streak artifacts, a body phantom was scanned at 25/50/150 mA and 80/160/320 rows and FIRST reconstruction was performed. It was confirmed that the image SD values in the shoulders have been improved and streak artifacts have been visually reduced, as compared with AIDR 3D. Image quality check was performed using the existing clinical data. Images obtained with FIRST were compared with those obtained with FBP and AIDR 3D. It was visually confirmed that no significant artifacts and missing anatomical structures occur in FIRST.
Representative diagnostic images, reviewed by an American Board Certified Radiologist, including chest, abdomen and pelvis exams were also obtained using the subject device which demonstrates that the device produces images of diagnostic quality and; therefore, performs as intended.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Quantitative Dose Reduction Evaluation: up to 82.2% dose reduction compared to filtered back projection. Equivalent low contrast detectability to FBP (range from 0.6 - 0.686) can be achieved with 51.7% to 82.2% less dose.

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.
Image Quality Evaluation
CT image quality metrics were performed, utilizing phantoms, which demonstrated that the subject device is substantially equivalent to or demonstrates an improvement to the predicate device with regard to spatial resolution, CT number accuracy, contrast-to-noise ratio, noise properties, uniformity, slice sensitivity profile, low contrast detectability and standard deviation of noise. Studies were also conducted to demonstrate equivalence and/or improvements in CT number accuracy in water phantoms and artifact reduction using body phantoms.
Quantitative Dose Reduction Evaluation
The subject device demonstrated a dose reduction claim of up to 82.2% compared to filtered back projection as demonstrated by a model observer evaluation which showed that equivalent low contrast detectability to FBP (range from 0.6 - 0.686) can be achieved with 51.7% to 82.2% less dose using FIRST1.0 at Standard setting for thin (0.5 mm) reconstruction slice thickness in simulated body phantom (MITA-FDA phantom with a body ellipse surrounding it).
Artifact Reduction
For truncation artifacts, a body phantom was scanned at 25/50/150 mA and 80/160/320 rows and FIRST reconstruction was performed. It was confirmed that the image SD values in the shoulders have been improved and streak artifacts have been visually reduced, as compared with AIDR 3D. For streak artifacts, a body phantom was scanned at 25/50/150 mA and 80/160/320 rows and FIRST reconstruction was performed. It was confirmed that the image SD values in the shoulders have been improved and streak artifacts have been visually reduced, as compared with AIDR 3D. Image quality check was performed using the existing clinical data. Images obtained with FIRST were compared with those obtained with FBP and AIDR 3D. It was visually confirmed that no significant artifacts and missing anatomical structures occur in FIRST.
6
Representative diagnostic images, reviewed by an American Board Certified Radiologist, including chest, abdomen and pelvis 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.
18. CONCLUSION
The Aquilion ONE Vision with FIRST 1.0 (CCRS-001A), performs in a manner similar to and is intended for the same use as the predicate device, as indicated in product labeling. Based upon this information, conformance to standards, successful completion of software validation, application of risk management and design controls and the performance data presented in this submission it is concluded that the subject device is substantially equivalent in safety and effectiveness to the predicate device.
