The Sheikh Zayed Tower at The Johns Hopkins Hospital is home to a brand new, state-of-the-art computed tomography (CT) scanner, thanks to funding support from Toshiba. The Aquilion ONE ViSION Edition scanner will be used by the Division of Cardiology to scan patients’ hearts. Data collected from the scans, as well as a great deal of other data, will help fuel another joint venture between Johns Hopkins and Toshiba: the Toshiba Center for Big Data in Healthcare at Johns Hopkins.

The new CT system can image a heart in one rotation, capturing both anatomical and functional data. With its 78-centimeter bore and fast rotation, the system can also accommodate more patients in less time, including bariatric patients and patients with fast heart rates. The scanner improves patient safety with Toshiba’s third-generation software, AIDR 3D, which incorporates enhancements that significantly reduce radiation dose compared with conventional scanning.

“Toshiba’s Aquilion ONE ViSION Edition 640-slice CT scanner is ideal for the cardiac imaging research we plan to undertake on enhanced perfusion,” says Joao Lima, M.D., professor at the Johns Hopkins University School of Medicine. “Its ability to cover 16 centimeters in a single rotation, capturing the entire heart, will not only help us find the earliest signs of restricted blood flow, but will also allow for scanning of patients with arrhythmia, or irregular heartbeats.”

This new technology could allow doctors to find these types of issues before symptoms appear or organs become permanently damaged. The technology will also be able to capture large amounts of data from scans. With this joint project between multiple Toshiba groups and The Johns Hopkins University, Toshiba is leveraging its sophisticated data-mining technology and diagnostic imaging analysis expertise to pull metrics and add to The Johns Hopkins University’s existing nonimaging data.

The Toshiba Center for Big Data in Healthcare and Johns Hopkins plan to use the data to identify similarities in backgrounds and symptoms in populations of patients to produce prototype products. The hope is to eventually transform health care into a more efficient, cost-effective, data-driven enterprise.

Johns Hopkins has had a collaborative relationship with Toshiba for more than 10 years. Other joint ventures include Johns Hopkins’ use of several of Toshiba’s advanced CT systems. Johns Hopkins was one of the first facilities in the United States to install Toshiba’s Aquilion ONE dynamic volume CT system, a 320-slice CT.

A ribbon-cutting ceremony took place on July 14 at The Johns Hopkins Hospital to mark the installation of the Aquilion ONE ViSION Edition CT scanner.
