A radiation focal position detecting method for detecting a positional displacement of a focal point of a radiation source in a radiation tomographic imaging apparatus is provided. The fingerprint patterns reveal the health of lysosomal organelles, specific LSD, and clinical severity. Such a process allows for the controlled spin-polarization of carriers in a semiconductor channel, and hence the development of spin-based microelectronics, without having to inject spin-polarized carriers from a ferromagnet into a semiconductor channel. The formed-goods of the present invention is used for wrapping film, wrapping container and foaming goods. The weighted correlation technique combines signals from two correlator modules, an R-correlator module and a W-correlator module, to generate the correlation output.
