To a first approximation ρ is a piecewise constant function, and this indicates thatbρ(k) = O(kkk−1). In order to get the best signal-to-noise ratio, we clearly need to collect samples from a neighborhood of (0,0) in k-space. WebTo capture an image, the MRI system uses and sends magnetic and radiofrequency waves into the patient’s body. The energy emitted by the atoms in the magnetic field … getting training accredited
