- Abstract
- A whole-body voxel model of a 7-year-old male volunteer was developed from 384 axial magnetic resonance images (MRIs). The MRIs were acquired with intervals of 3 mm for the entire body in a body coil. In order to reduce the MRI acquisition time for the child the repetition and echo times under T1 weighted image were chosen to be 566 ins and 8 ins, respectively. The MRIs were classified according to 30 types of tissues with known electrical parameters. The developed voxel model was adjusted to the physical average of 7-year-old Korean boys. The boas weight of the adjusted model, calculated with the moss tissue densities, is within a 6% difference from the 50th percentile weight.
