A motion sensing MRI coil allows correction of motion-induced image artifacts by the MRI machine or on a machine independent basis using correction circuitry associated with the coil. 1\xb0 in a powder X-ray diffraction. The transform coefficients required to decode an image from its head position line by line are encoded by Golomb coding using one line of a subband as a unit to generate a code sequence, which is output to an image output apparatus. Therefore, the photoexcitation process may be used to pre-treat or post-treat the substrate or material, to deposit the silicon-containing material, and to enhance chamber cleaning processes. The gate driver is configured to modulate a gate pulse therein, and output the modulated gate pulse.
