To perform these operations directly on the B-Rep is complex and very tedious; a better approach is to break it down into precise piecewise planar representation.
Personalized predictive lung dosimetry by 99mTc MAA SPECT/CT is clinically feasible, safe, and more precise than conventional planar methodology for 90Y radioembolization radiation planning.
Even the drywall must be hung and finished with exacting precision, so that each corner, curve and planar surface is precise to 1/64th of an inch.
However, difficulties arise when trying to couple light into these on-chip devices, as a high on-chip density and planar geometry require a precise optical probe which can couple exclusively to a particular device.
However, we found planar methodology to be less precise than SPECT/CT methodology.
Each volume was acquired using a multi-slice peripherally-gated doubly refocused spin echo-echo planar imaging sequence, optimized for precise measurement of the diffusion tensor in parenchyma, from 60 contiguous near-axial slice locations with isotropic (2.4 × 2.4 × 2.4 mm) voxels.
We use a multi-planar display to define the precise post-firing position of the LCNB track, because needle visualisation by 2D within a lesion may be somewhat more subjective and be influenced by partial-volume effects towards the periphery of the lesion that might reduce the yield for small lesions.
Similar to the problem in the fabrication of planar compound eye, the requirement of precise alignment of the photodetector and microlens is hard to achieve.
Then, a 3D-US volume data set (10 Mb) was acquired and converted into a multi-planar imaging display to define the precise post-firing position of the needle.
However, it must be noticed that, up to now, precise deposition of metal catalyst film on a non-planar surface was still difficult.
