ZTE MRI:
Acquisition parameters were: bandwidth = 250,000 Hz, acquisition time =
0.512 ms, repetition time = 2.048 ms, excitation pulse angle = 5.0
degrees, missing data = 1.7 dwells, minimum spooling = 2.0 cycles/pixel,
FOV = (2.0 cm) (2.0cm) (2.0 cm) to (4.0 cm) (4.0 cm) (4.0 cm). Dummy
scans used were 2,000, resulting in a duration of dummy scans of 4.096
s. With an imaging matrix of 256 x 256 x 256 the achieved nominal
resolution was 78.12 x 78.12 x 78.12 µm3. Oversampling
factor was set to 8. With NS =320, the total acquisition time was 7
hours and 7 minutes per one 3D image. Other combinations of the FOV and
matrix were also tested to take account of possible aliasing artifacts.
