GE unveils 3T and 1.5T scanners

GE Healthcare played to high-field enthusiasts visiting the RSNA exhibit floor Sunday, unveiling three MR scanners - one at 3T and two at 1.5T.

The Signa HDx 3T and Signa HDx 1.5T are built on a 32-channel architecture and support advanced clinical applications, including PROPELLER for motion-resistant brain imaging, VIBRANT-XV breast scanning, LAVA-XV body imaging, and TRICKS-XV time-resolved angiography. The Signa HDe, a value-driven 1.5T scanner, comes in four- and eight-channel configurations, and sports a small footprint for easy installation.

The 3T and premium 1.5T systems feature a new XVRE reconstruction engine; advanced parallel imaging algorithms; new acquisition strategies; and an interlocking, high-density head, neck, and spine coil system.

Signa HDx 3T utilizes high-density coils developed for the company's previously launched HD 3T system, which will remain in the GE line-up. New this year is the Signa HD breast coil, which supports multi-dimensional parallel imaging and biopsy capability, and a high-density hybrid extremity coil.

Signa HDx takes the flagship position in GE's 1.5T portfolio. It utilizes a Signa HD peripheral vascular lower leg array, which provides images of the lower leg and foot vessels.

The value-oriented Signa HDe 1.5T builds on the high definition platform, but offers lower operating costs and requires less overall siting space. With a 30% smaller footprint than a typical 1.5T system, the scanner can be sited where most 1.5T MR systems cannot, according to the company. Installation can be performed in about one week.
