GE updates Signa platform

The latest evolution of GE Healthcare's Signa HD x (high definition x) platform offers MR pulse sequences that overcome barriers to diagnostic scans in some difficult-to-image patients. The xt version, shown at the RSNA meeting, features two major innovations: 3D Cube and Ideal. 3D Cube's capture of submillimeter isotropic voxels allows the viewing of a volumetric data set in any plane and the visualization of lesions as small as 2 mm. Ideal improves image clarity through uniform fat suppression and handling multiple contrasts from fat, water, and the two combined, both in-phase and out-of-phase. It also reduces or eliminates artifacts due to chemical shift of metal implants, such as orthopedic screws or dental work, and eliminates misregistration between fat and water.
