MRIQ: Geometric Image Distortion all Axes, Varies Slice to Slice on Any Coil or PSD, WHOLE or ZOOM Gradient Modes See Long Description and Attachment This problem began suddenly. The previous night the customer was having no problem. Upon arrival the next day, this problem existed. On a 3T 12X system with M5 software, customer began getting geometric distortion with both WHOLE and ZOOM gradients. Images on all axes showed geometric distortion that varied slice to slice. Problem occurred with any coil or PSD but would change how it looked when FOV was changed. Even and odd images from the same series alternately distort on opposite sides of isocenter (see Attachment for problem images from the site). Diagnostics all passed. Swapping gradient amps around and replacing the Exciter, GP3 and STIF boards had no effect on the problem. There was no obvious software corruption, gradcal values unchanged.
