UC Davis Health Images First U.S. Patient Using Ultra-High Resolution CT with Canon Medical’s Aquilion Precision

Sponsored by Businesswire

University of California, Davis (UC Davis) Health is the first
institution in the U.S. to use Ultra-High Resolution CT (UHR CT) for
clinical imaging, thanks to the installation of the Aquilion
from Canon
Medical Systems USA, Inc
. Reports in the initial use of this
technology from global centers indicate significantly increased
visibility of small anatomical structures is possible, allowing UC Davis
to now offer their CT patients better image resolution than available in
the U.S. previously.1,2,3,4 In collaboration with Canon
Medical, UC Davis Health plans to continue investigating the diagnostic
potential now available because of the significant improvement in

Featuring an all-new detector as well as tube, gantry and reconstruction
technologies, the Aquilion Precision may make it possible to help the
facility expand visualization of anatomical structures and conditions.
The system’s features make it capable of resolving anatomy as small as
150 microns for advanced image detail. Innovative dose efficiency with
detector channels that are only 0.25 mm thick, combined with
improvements in scintillator quantum efficiency, detector circuitry and
other DAS components, result in a dose-efficient detector with UHR CT
capabilities. The system also features resolution never before seen in
CT imaging with the industry’s smallest focal spot tube at 0.4 mm x 0.5
mm and the industry’s first 1024 and 2048 (research only) reconstruction
matrix for further increased resolution.

“The installation and use of the Aquilion Precision on the UC Davis
Health campus is more than the introduction of a new CT system, it is a
foray into a new paradigm in CT imaging to help improve patient care,”
said Dominic Smith, senior director, CT, PET/CT, and MR Business Units,
Canon Medical Systems USA, Inc. “Canon Medical is looking forward to
working with UC Davis Health to explore new territories in diagnostic
imaging, thanks to the technical and clinical value of this technology.”

A ribbon cutting opening ceremony will be held Friday, April 26, 2019,
to commemorate the installation of the Aquilion Precision. Leadership
from UC Davis Health, Canon Medical and members of the local community
will be present.
