In this manner, the authors were able to discriminate less than five infected hepatocytes per liver using planar luminescence imaging.
Optimal means that these representations asymptotically match the respective entropy of the two classes, namely 2 bits per edge for 3-connected planar graphs, and 1.62 bits per triangle, or equivalently 3.24 bits per vertex for triangulations.
Thresholding value was fixed for all image stacks, and at least 4 positions and 20 planar images per position were analyzed.
Thirty-seven echo planar images per volume sensitive to blood oxygenation level-dependent (BOLD) contrast were obtained (TR = 2000 ms; TE = 35 ms; 3.5×3.5 mm in-plane resolution; Field of View [FOV], 224 mm).
Twenty-seven whole brain T2*-weighted echo planar images per volume with BOLD contrast were obtained (TR = 3000 ms, TE = 40 ms, flip angle 90°, matrix: 64 × 64, FoV: 24 × 24 cm, slice thickness 5 mm, bandwidth 62.5 kHz).
Further, a cost analysis is presented to determine the preferred design configurations that minimize the cost per unit area of the planar waveguide concentrator coupled to the receiver.
Following injection, all patients underwent preoperative lymphoscintigraphy imaging per institutional protocol, which involved planar imaging (±dynamic) and/or fused single-photon emission computed tomography/CT (SPECT/CT).
Diffusion-weighted imaging (DWI) was initially used for the qualitative assessment of the impact of a gradient applied for a certain time per area unit on echo planar MR images.
However, the total number of adhesions formed by cells cultured on grooved substrates increased by proportionally (planar 187 ± 75 per cell, 240 nm 216 ± 74 per cell and 540 nm 261 ± 96 per cell), resulting in relatively similar FA proportions on each surface (planar 66±7 7% FA, 240 nm 65 ± 7% FA and 540 nm 63 ± 7% FA).
