Abstract: A first and a second image are expressed in a common coordinate system by applying a geometric transformation to the second image so as to map a structure in the second image onto a corresponding structure in the first image in a common coordinate system. Starting from initial values, the parameters of the geometric transformation are updated taking into account the result of an evaluation of a cost function. Measurements are performed in the common coordinate system.
Abstract: A relief print master is created by printing a sequence of layers on top of each other by an inkjet printing system. The top layer corresponds with the binary halftoned image that is to be printed by the print master and the lower intermediate layers are supporting layers. The features in a lower supporting layer have an area that is larger than the corresponding features in a higher supporting layer. A circular spread function is applied on the features of a higher intermediate layer to increase the area of the features in a lower intermediate layer. By using a sequence of two non-circular spread functions, the circular spread function is approximated and the number of required calculations can be reduced.

Abstract: A process for producing a non-transparent microvoided self-supporting film comprising the steps of: i) mixing at least one linear polyester having together monomer units consisting essentially of terephthalate, isophthalate and aliphatic dimethylene with the molar ratio of isophthalate monomer units to terephthalate monomer units being at least 0.
Abstract: A digital printer includes a digital printing unit for digital printing an image onto a printing substrate during relative movement between a print head and the printing substrate, and a printing table for holding the printing substrate during the digital printing. The printing table is firmly fixed to the digital printing unit during the digital printing of the image onto the printing substrate and is released from the digital printing unit prior to and after the digital printing of the image onto the printing substrate. The printing table may be moved between a printing position, in which it is firmly fixed to the digital printing unit, and a printing substrate feeding position, in which it supports feeding and removing of the printing substrate from the printing table.

Abstract: For each of a number of landmarks in an image an initial position of the landmark is defined. Next a neighborhood around the initial position, comprising a number of candidate locations of the landmark is sampled and a cost is associated with each of the candidate locations. A cost function expressing a weighted sum of overall gray level cost and overall shape cost for all candidate locations is optimized. A segmented anatomic entity is defined as a path through a selected combination of candidate locations for which combination the cost function is optimized.

Abstract: A method for making a flexographic printing master includes the steps of providing a flexographic printing support: applying image-wise on the flexographic printing support subsequent layers of radiation curable liquid by an inkjet printing device whereby one or more applied layers are immobilized using a curing device before one or more subsequent layers are applied, such that a relief with a top hat profile is obtained; and grinding the relief so that the height DT of a top hat segment is reduced. An imaging apparatus includes structure to perform the above method.

Abstract: A system and method for automatically handling data objects within groupings in a PACS network. Where a data object belonging to one grouping is moved to or copied into another grouping, certain associated data objects will automatically be moved or copied to the other grouping. Similarly, where some data objects are deleted from a grouping, data objects associated with objects which will not be deleted are automatically protected from deletion.
Abstract: A redundant image storage system for archiving an image data file within at least two picture archiving and communication systems (PACS), said system including coupled source and destination PACS networks. The source PACS network stores and transmits the image data file. The destination PACS is associated with a Remote Archive Locations record and a Source PACS Archived flag. The destination PACS network receives the image data file from the source PACS network, stores the image data file and determines whether the image data file should be stored back on the source PACS network and if not then sets the value of the Source PACS Archived flag to be true. The destination PACS network only sends the image data file to the source PACS network for storage if the Source PACS Archived flag is false.
