Optical films having anti-Moir\xe9 and anti-wetout features are described, along with systems and methods for making these optical films. The use of HTML or other markup language documents to create menu pages for display on a touch sensitive menu screen makes the menu screen easily reconfigurable to accommodate functional upgrades to the dedicated purpose device. Furthermore a method is disclosed for producing the circuit arrangement on a substrate. Using non-rigid image registration between pre-operative and intra-operative images, the position of the target andor other part of the anatomical region may be determined. The Bessel function having an approximately rectangular waveform in the frequency domain increases the signal-to-noise ratio, allows thinner slice thicknesses, and allows more contiguous slices, resulting in a better MR image and a more efficient MRI apparatus.
