The Aquilion One has a coverage area of 320 detector rows, can capture actual organ movement–like blood flowing through the heart–and can image an entire organ in one gantry rotation. Additionally, the Aquilion One can capture the heart in one heart beat, said Toshiba spokesperson Rob Young in an interview.

Toshiba’s proven noise reduction algorithms is due to Boost 3D, an adaptive 3D filter which corrects the raw data where there is a disproportionate loss in x-ray signal and applies the 3D filter locally to reduce the image noise and streak artifacts.

The technique can either be applied to enhance images using conventional mAs settings, or to allow low-dose imaging with acceptable image quality, Young said.

Quantum Denoising Software (QDS) a second technique also helps minimize noise in the reconstructed images by smoothing areas of uniform density, while preserving the edge information of the image. QDS works in both two and three dimensions and help reduce image noise thus allowing a corresponding savings in patient dose. Young stated that both techniques help reduce dose by up to 80 percent.

Young emphasized a reduction in radiation exposure is noteworthy in the pediatric population. Many children with congenital anomalies undergo repeated imaging studies. Not only are they spared excessive radiation exposure with the Aquilion One, but they also do not need to be heavily sedated, Young said.

This is an advantage for workflow in a busy facility. Heavy sedation can add hours in the front end, as well as significant time in the back end while the patient recovers, he said.

Aquilion One has the capability to do 4D perfusion imaging, showing up to 16 cm of anatomical coverage which is enough to capture the entire brain or heart, and show its movement such as blood flow.
