It may be said that signal processing is the coin of the electronic realm, and here contributors examine topics as hyperbolic geometry, Nehari's theorem, electronic circuits and analog signal processing, engineering applications of the Motion-Group Fourier transform, fast x-ray and beamlet transforms for 3D data, Fourier analysis and phylogenetic trees, diverse tomography, matrix-valued spherical functions, image resolution for MRI, image compression, integrating sensing and processing for statistical pattern recognition, sampling of functions and sections for compact groups, the Cooley-Tukey FFT and group theory, signal processing in optic fibers, and the generalized spike process.
IMRT differs from 3D-CRT in that each x-ray beam is broken up into many "beamlets," and the intensity of each beamlet can be adjusted individually.
In a 1995 run of the Beamlet -- a $37 million, 200-foot-long prototype of one of NIF's 192 laser "arms" -- the device imploded due to microscopic flaws in the glass, causing $228,000 in damages and shutting down the project for nearly seven weeks.
In addition, VoLO represents the first use of a new Non-Voxel Broad Beam (NVBB) calculation algorithm that takes advantage of both the GPU's unparalleled speed and the TomoTherapy Systems unique beamlet radiation delivery system to develop dose distributions from the perspective of each beamlet (up to tens of thousands in any given plan) as they pass through the patient's body.
