Abstract: Individuals in a population are paired together to produce children. Each individual has a subset of features obtained from a group of features. A genetic algorithm is used to construct combinations or subsets of features in the children. A classification algorithm is then used to evaluate the fitness or cost value of each child. The processes of reproduction and evaluation repeat until the population reaches a given classification level. A different classification algorithm is then applied to the population that reached the given classification level.

Abstract: A method of delivering intensity modulated radiation therapy (IMRT) is disclosed. An intensity profile for the treatment of a patient is provided which spans a prescribed field width and includes a discrete profile having intensity values at each of a plurality of sample points bounded by the prescribed width. The prescribed width is compared to a maximum field width provided by the radiation treatment system. The intensity profile is split into a plurality of intensity profile portions, each having respective widths less than the maximum width if the prescribed width is greater than the maximum width. The prescribed field is also divided into a plurality of different profile portion split arrangements. A monitor unit (MU) efficiency is calculated for each of the arrangements. One of the arrangements is selected for delivery by the system using a leaf sequencing method.

Abstract: Embodiments of the present invention use the results of a plurality of defect detecting tests and adjust the result of each test in a manner that reflects the accuracy of the test that produced it. A manufactured unit can then be evaluated using a mathematical combination of the adjusted results.

Abstract: Representative embodiments are directed to systems and methods for processing training data for a statistical classification application. In one embodiment, confidence values are calculated for training data elements to identify the probabilities of the training data elements belonging to identified classes. An interactive scatter plot is generated using the calculated confidence values. The scatter plot visually indicates the confidence values of points in the scatter plot. Accordingly, the user is able to identify potentially misclassified training data elements. The user may select training data elements from the scatter plot and reclassify training elements as appropriate. Upon reclassification, the confidence values may be recalculated and the scatter plot revised.

Abstract: A method of determining a treatment plan for intensity modulated radiation treatment (IMRT) divides a three-dimensional volume of a patient into a grid of dose voxels. At least a portion of the dose voxels are designated to belong to at least one target or to at least one critical structure. An ionizing radiation dose as delivered by a plurality of beamlets each having a beamlet intensity is modeled. A non-linear convex voxel-based penalty function model is provided for optimizing a fluence map. The fluence map defines the beamlet intensities for each of the plurality of beamlets. The model is then solved based on defined clinical criteria for the target and the critical structure using an interior point algorithm with dense column handling to obtain a globally optimal fluence map.

Abstract: An inspection system inspects features of an object using a feedback mechanism. The inspection system includes a processor that receives image data representing the object. The processor is operable to determine parameter modification information from the image data and modify an image parameter used during the production of the image data with the parameter modification information. The modified image parameter is used during the production of subsequent image data representing the object.

Abstract: A method of delivering radiation treatment using multi-leaf collimation includes the step of providing a radiation fluence map which includes an intensity profile. The fluence map is converted into a preliminary leaf sequence, wherein the preliminary leaf sequence minimizes machine on-time and is generated without leaf movement constraints. The leaf movement constraint is imposed on the preliminary leaf sequence. At least one constraint elimination algorithm is then applied, the algorithm adjusting the preliminary leaf sequence to minimize violations of the constraint while providing the desired fluence map and minimized radiation on-time. The method can be applied to SMLC and DLMC systems, and can include adjustment for the tongue-and-groove effect.

Abstract: Optimizing tester performance using Operating Characteristics curves. By modeling the Operating Characteristics of classifiers used in testing systems, tester performance is optimized. Classifiers are constructed using sample data. Operating Characteristic curves for each classifier are constructed, each Operating Characteristics curve representing a design alternative. The Operating Characteristic curves are combined with cost models from which design decisions may be made.

Abstract: A telephone cord having a digital transmission includes six lines and has two ends each provided with a connecting terminal which is formed with six insertion slots each mating with and connected to a corresponding one of the six lines for insertion of one of six metallic guide plates. When either one of the metallic guide plates is inserted into the respective insertion slot, the metallic guide plate is electrically connected to the respective line of the telephone cord. Thus, the telephone cord has double functions of telephone communication and digital network communication, so that the telephone cord combines the functions of the ordinary telephone cord and the ordinary network cord, thereby greatly enhancing the versatility of the telephone cord.
