MR image synthesis using multiple spin echoes

A new method of spin echo image synthesis is reported. This method uses a combination of multiple spin echo image trains as source images. The combination and the coefficient of the source image are essential to determine both the TE and the quality of the synthesized image. The coefficient is arbitrarily specified by the operator and is used in the image processing. T2 calculation is not prerequisite to the process. Some of the synthesized images exhibit higher S/N ratios than the original ones representing the same TE. The images at arbitrary TE are able to be formed by this method as well as previously reported methods. But the images for TRs different from that used to acquire the source images cannot be produced, because there isn't enough T1-information in the sources. (author)
