Intended Use
This device is indicated to acquire and display cross sectional volumes of the whole body, to include the head, with the capability to image whole organs in a single rotation. Whole organs include but are not limited to brain, heart, pancreas, etc. The Aquilion ONE has the capability to provide volume sets of the entire organ. These volume sets can be used to perform specialized studies, using indicated software/hardware, of the whole organ by a trained and qualified physician. FIRST 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 Network methods for abdomen, pelvis, lung, cardiac, extremities, head, and inner ear applications. The spectral imaging system allows the system to acquire two nearly simultaneous CT images of an anatomical location using distinct tube voltages and/or tube currents by rapid KV switching. The Xray dose will be the sum of the dose at each respective tube voltage and current in a rotation. Information regarding the material composition of various organs, tissues, and contrast materials may be gained from the differences in X-ray attenuation between these distinct energies. When used by a qualified physician, a potential application is to determine the course of treatment. PIQE* is a Deep Learning Reconstruction method designed to enhance spatial resolution. By incorporating noise reduction into the Deep Convolutional Network (DCNN), it is possible to achieve both spatial resolution improvement and noise reduction for cardiac, abdomen and pelvis, and lung applications, in comparison to FBP and hybrid iterative reconstruction. CLEAR Motion is a Deep Learning Reconstruction (DLR) method designed to reduce motion artifacts. A Deep Convolutional Network (DCNN) is used to estimate the patient's motion. This information is used in the reconstruction process to obtain lung images with less motion artifacts.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Performance Testing - Bench:
Image Quality Evaluations:
CT image quality assessments were performed, utilizing phantoms, to evaluate PIQE Lung Image Quality, PIQE Body Image Quality and Spectral Cardiac Image Quality of the TSX-308A (Aquilion ONE) system relative to the predicate device, TSX-306A (Aquilion Prism) with regard to Contrast-to-Noise Ratios, CT Number Accuracy, Uniformity, Slice Sensitivity Profile, Modulation Transfer Function, Standard Deviation of Noise Power Spectra, and Low Contrast Detectability. It was concluded that the subject device demonstrated equivalent or improved performance, compared to the predicate device, as demonstrated by the results of the above testing.

CLEAR Motion Evaluations:
Performance tests were conducted to evaluate the performance CLEAR Motion, utilizing phantoms and clinical images. These studies included comparing clinical lung images, a water phantom and a thoracic dynamic phantom (evaluated at 12 BPM), reconstructed with AIDR3D, AiCE and/or FBP with and without CLEAR Motion applied. Conclusions from these studies demonstrated that CLEAR Motion performed as intended, in that motion artifacts were significantly reduced and CT Numbers were maintained, compared to standard reconstructed images in which CLEAR Motion was not applied.

Performance Testing - Clinical Images:
Representative body, cardiac, chest, head, and extremity diagnostic images, reviewed by American Board-Certified Radiologists, were obtained using the subject device and it was confirmed that the reconstructed images using the subject device were of diagnostic quality.
