Abstract
Three-dimensional motion picture of thoracoabdominal organ due to respiration offers potential application such as us use in diagnosis of those organs, radiotherapy and/or planning, improvement of PET or SPECT image quality. We have developed a method for reconstructing a four-dimensional magnetic resonance image (4D-MRI) of respiratory organ motion from time sequential images of two-dimensional (2D) MR. The developed method properly synthesizes a set of 2D MRI acquired at different slice position using a navigator slice orthogonal to those data slices. The method is introduced and a few examples of 4D-MR images are demonstrated. A prospective method for shortening the acquisition time is also shortly described. As an application of 4D-MRI, diaphragm is extracted from the 4D-MRI and its motion along to body axis is visualized.
