gradient magnetic field

gradient magnetic field

An MRI term for a small linear magnetic field superimposed on the large static magnetic field during an MRI scan, the strength (amplitude) and direction of which change during the scan such that each small volume element (voxel) within the imaging volume resonates at a different frequency, allowing spatial encoding to be performed.

For the implementation of a high-quality finishing surface treatment of special optical workpieces magnetorheological polishing method is used [3, 4], which is based on software-controlled tangential material removal by a magnetorheological polishing fluid (MRPF) jet, formed by the gradient magnetic field, with its local contact with the object of the treatment.
