20100232725 | TEMPERATURE ARTIFACT CORRECTION - A system and method of generating a template of at least one artifact for use in image correction is disclosed. An image containing the artifact is generated using at least two homogeneous exposures, each generated at a different detector operating temperature. The local variance of grey values at each pixel position in the image is calculated. Each pixel in the image is then classified. A binary image is generated based on the classification. The template is then formed based on both the binary image and the image data containing the artifact. | 09-16-2010 |

20120027259 | SYNCHRONIZATION OF TWO IMAGE SEQUENCES OF A PERIODICALLY MOVING OBJECT - A method and an apparatus for correlating two image sequences of a periodically moving object with respect to the periodicity is described. A first frame sequence of the object moving with the first periodicity is acquired. Therein the first frame sequence comprises at least one cycle of motion. A second frame sequence of the object moving with the second periodicity is acquired. Therein the second frame sequence comprises at least one cycle of motion. The first and the second frame sequences are synchronized with respect to the respective periodicity such that same phases of motion of the periodically moving object are correlated to be presented simultaneously. The present invention allows to compare sequences representing a periodical motion with a different number of frames in each of the sequences for the same cycle of motion. Thereby, e.g. image sequences of a beating heart acquired before and after a therapy may be presented in a synchronised way and therefore may be easily compared. | 02-02-2012 |

20080304034 | DOSE CONTROL FOR OPTICAL MASKLESS LITHOGRAPHY - A lithographic apparatus comprises a patterning device, a projection system, and a controller. The patterning device is configured to pattern a beam of radiation. The radiation beam comprises a plurality of pulses of radiation. The projection system is configured to project the patterned beam of radiation onto a substrate coated with a layer of radiation sensitive material. The controller is arranged to control a total energy of a respective pulse of the plurality of pulses of the radiation beam. The controller is configured to take into account information indicative of properties of the layer of radiation sensitive material on a part of the substrate onto which the radiation beam is to be projected. | 12-11-2008 |
20110134399 | Lithographic Projection Apparatus - A lithographic apparatus arranged to transfer a pattern onto a substrate is disclosed. The lithographic apparatus comprises a power supply and an electrical connector. The electrical connector electrically connects the power supply to another component of the lithographic apparatus. The electrical connector comprises a laminate that comprises, in order, a first conducting layer, a first flexible insulating layer, a conductor configured to carry an electrical current, a second flexible insulating layer and a second conducting layer. | 06-09-2011 |
