Aquilion ONE (TSX-308A/3) V1.4 with PIQE Reconstruction System

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 Neural Network methods for abdomen, pelvis, lung, cardiac, brain, 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 X-ray 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 Neural Network (DCNN), it is possible to achieve both spatial resolution improvement and

noise reduction for cardiac, abdomen, and pelvis applications, in comparison to FBP and hybrid iterative reconstruction..
