Single-point imaging method for imaging area in object, involves determining intervals of scanning time points by maximum dimension of image area in local coding which is given by magnetic field gradient

摘要

The method involves producing a free induction signals by atomic nuclei. A magnetic field gradient is produced for local coding of induction signals by changing the phase of magnetic resonance signals. Raw data is generated by multiple scanning of free induction signals to scanning time points which have equal intervals to each other. Image data is reconstructed from the raw data set by Fourier transformation. The intervals of scanning time points are determined by maximum dimension of the image area in the local coding which is given by magnetic field gradient.
