They were then irradiated at 5 hpf by alpha particles using a planar 241Am source with an activity of 0.1151 μCi for 24 s (priming dose), and subsequently at 10 hpf using the same source for 240 s (challenging dose).
A new stereo-photolithography technique to create three-dimensional micro-components using a planar, layer-by-layer, process of exposure has been developed.
The animals were euthanized 24 h later and biodistributions were determined by imaging the excised tissues using a planar fluorescence imaging station with a deep-red filter set (λex = 590 nm, λem = 670 nm).
The sound production is predicted by using a 2-D planar point vortex model combined with the Vortex Sound Theory.
Functional images were obtained by using a gradient echo-planar imaging (EPI) sequence (TR = 2000 ms, TE = 30 ms, flip angle = 90, slice thickness = 4mm, slice gap = 1 mm, FOV = 24cm × 24cm, Matrix = 64 × 64), and 180 continuous EPI functional volumes were acquired axially over 6 min. All the subjects did not complain any discomfort and feel asleep during scanning.

A routine T1 weighted imaging was first performed, and then the resting-state fMRIs were obtained by using an echo-planar imaging sequence with the following parameters: voxel size 3.75 × 3.75 × 5 mm3, TR 2000 ms, TE 30 ms, FOV 240 × 240 matrixatrix 64 × 64, and slice thickness 5 mm with no gap, number of slices 30, number of time points 180.
Functional images were collected axially by using an echo-planar imaging (EPI) sequence sensitive to BOLD contrast.
The resting-state functional images were acquired by using an echo-planar imaging sequence with the following parameters: 36 axial slices, thickness/skip = 3/1 mm, in-plane resolution =64 × 64, repetition time = 3000 ms, echo time = 30 ms, flip angle = 90, field of view = 220 × 220 mm, 180 volumes.
The resting-state functional images were acquired by using an echo-planar imaging sequence with the following parameters: interleaved, 33 axial slices, thickness = 3.0 mm, in-plane resolution = 64* 64, repetition time = 2000 ms, echo time = 30 ms, flip angle = 90, field of view = 220* 220 mm, 240 volumes (8 min).
