Method and apparatus for fast scatter simulation and correction in computed tomography (CT)
X-ray scatter simulations to correct computed tomography (CT) data can be accelerated using a non-uniform discretization of the RTE, reducing the number of computations without sacrificing precision. For example, a coarser discretization can be used for higher-order/multiple-scatter flux, than for first-order-scatter flux. Similarly, precision is preserved when coarser angular resolution is used to simulate scatter within a patient, and finer angular resolution used for the scatter flux incident on detectors. Finer energy resolution is more beneficial at lower X-ray energies, and coarser spatial resolution can be applied to regions exhibiting less X-ray scatter (e.g., air and regions with low radiodensity). Further, predefined non-uniform discretization can be learned from scatter simulations on training data (e.g., a priori compressed grids learned from non-uniform grids generated by adaptive mesh methods). |

Work vehicle reduction drive assemblies containing high contact ratio, configurable gearbox reductions
A work vehicle reduction drive assembly includes a drive having a drive shaft mechanically linked to a movable work component through a planetary gear train is. The planetary gear train includes a ring gear having a tooth count of Tring, a sun gear having a tooth count of Tsun, and a planet-carrier assembly including a plurality of planet gears each having a tooth count of Tplanet. Tring, Tsun, and Tplanet are selected such that each planet gear in the plurality of planet gears contacts at least two teeth of the sun gear and at least two teeth of the ring gear in all rotational positions of the planetary gear train. The sum of Tring and Tsun yields a positive integer when divided by a first number from a set {3, 4, 5} and when divided by a second number from the set {3, 4, 5}. |
