Gradient echo sequences are widely used in magnetic resonance imaging (MRI) for numerous applications rThe rate at which the static field changes over distance, or the B 0 fringe field spatial gradient, is responsible for the magnetic attraction of ferromagnetic objects. Movement within the fringe field is deemed to be responsible for various mild sensory effects (described later) and becomes more of an issue at high field strengths.Visual field testing is of special importance in neurology. The visual fields can be roughly assessed in the neurologist’s office or at the bedside with so-called finger perimetry (or digital confrontation; Fig. 3.5). The examiner sits directly in front of the patient and the patient fixes one eye on the examiner’s nose. A complex mixture of electromagnetic fields is used in magnetic resonance imaging (MRI): static, low-frequency, and radio frequency magnetic fields. Commonly, the static magnetic field ranges from one to three Tesla. The low-frequency field can reach several millitesla and with a time derivative of the order of some Tesla per second. The radiofrequency (RF) field has a magnitude in the ...Mansfield advanced this work further by introducing the concept of frequency and phase encoding using spatial magnetic field gradients, with the final image able to be reconstructed by the use of a Fourier transform (1977). Shortly thereafter, the team led by Professor Mallard in Aberdeen, Scotland, developed the first whole-body MR scanner. 3council houses in norfolk
the spatial gradients are measured anywhere within the defined imaging volume, which for many 1.5T MRIs is a 50 cm diameter sphere.
