Abstract: An automatic stacked parking or storage system includes a plurality of stationary docking cells, a plurality of carriages, and a central management system communicating with and controlling operations of the docking cells. Each docking cell has a ground driving device affixed on the bottom of the docking cell to drive a carriage horizontally in different directions of the docking cell, a docking cell control and interface unit (CIU), and one or more carriage position and ID sensor. A loaded carriage is moved horizontally by the ground driving devices of corresponding docking cells from a starting to a destination docking cell according to a route selected by a route optimization module. The location of the loaded carriage in the selected route is dynamically updated according to real time reports from each CIU of the corresponding docking cells. The system transports multiple loaded carriages at the same time for parking/storage and retrieval.

Abstract: A method in a computer for optimizing a dosage of intensity modulated radiotherapy (IMRT) comprises the steps of: dividing a three dimensional (3D) volume into a grid of dose voxels, wherein each dose voxel receives a dose of radiation from at least one pencil beam having a pencil beam weight and a gantry angle; selecting a first set of dose voxels from the 3D volume positioned within at least one of a planning target volume (PTV), organs at risk (OAR), and normal tissue in a neighborhood of the PTV; choosing a dose matrix from the first set of dose voxels; constructing a beam weight vector of individual beam weights for each pencil beam at each gantry angle; calculating a transfer matrix representing a dose deposition to the dose voxels from each pencil beam with unit beam weight; inverting the transfer matrix; performing a matrix multiplication of the inverted transfer matrix and the dose matrix and populating the beam weight vector with the results of the matrix multiplication; and iteratively modifying a
