A multi-layer dental panoramic and transversal x-ray imaging system includes an x-ray source; a digital imaging device capable of frame mode output with a sufficient frame rate; a mechanical manipulator having at least one rotational axis located in a position other than the focal point of the x-ray source; a position detection mechanism for detecting the camera position in 1D, 2D or 3D depending of the complexity of the trajectory; a final image reconstruction mechanism for reconstructing the final images out of the stored frames; a real time storage system such as RAM, hard drive or an drive array able to store all the frames captured during an exposure; and a digital processing unit capable of executing the reconstruction algorithm, such components being interconnected in operational arrangement. The system produces selectively dental panoramic x-ray images, dental transversal x-ray images and dental tomosynthetic 3D images from a frame stream produced by a high-speed, x-ray digital imaging device.

A calibration system (300) for a detector (328) includes a base member (302), a plurality of radiation sources (304)fixedly attached to the base member, and a positioning mechanism (306) attached to the base member. Each radiation source (394) is maintained at a different temperature and is configured to emit electromagnetic radiation. The positioning mechanism includes a movable member (308) having a single degree of freedom with respect to the base member (302), and a plurality of optical elements arranged (310) on the movable member. Each optical element corresponds (310) to one of the radiation sources (304) and each optical element is configured to at least be movable between a calibration position and a non-calibration position. When the optical element is in the calibration position, the optical element is configured to receive the electromagnetic radiation from its corresponding radiation source and to reflect the electromagnetic radiation to a detector.

The present invention involves a computer for implementing a complex database management system (100). A processor (110) has at least one complex database with extraction software (108). The database extraction software is capable of creating a perspective based data model from a user selected data table (104) of the database. A query is specified by user selection of attributes from a data table of the database. A perspective based data model is created from the user selected data base table of the database and related tables. The extraction software creates a query structure defining a plurality of paths providing a selected portion of the information in the database, which is presented to the user based on the perspective based data model. The query structure defines a plurality of paths and having a plurality of nodes, each of the nodes having a corresponding operand. A downward evaluation of the query structure is performed, proceeding from a starting object down downwardly through the paths. An upward evaluation of the query structure is performed, proceeding upwardly from the bottom of each path. The operands are resolved according to predetermined rules so that the number of evaluations of the nodes is less than the number of instances of each operand in the query structure.

The invention relates to a method for providing a service number, subject to a predefined charge, to a mobile subscriber, whose mobile subscription (1) is a visitor in the mobile network of a mobile operator other than the mobile operator with which the mobile subscriber has made a mobile subscription agreement. The invention concerns a method, in which a call connection is created between the customer's mobile station (1) and some second telephone device (15), on the basis of a request sent by the customer. When they desire a connection to some number, the customer sends a fixed-form short message to a number stated by the mobile operator. This short message contains the number to which the customer wishes a connection. Having received the short message, the equipment of the mobile operator calls the customer's mobile station (1). Once the customer has answered the call, the equipment of the mobile operator calls the subscription (15) stated in the customer's short message. Once this call has been answered, the equipment of the mobile operator links the call connections in such a way that a call connection is formed between the customer's mobile station (1) and the desired subscription (15). In the method, billing is carried out in such a way that the possessor of the destination subscription is billed for at least part of the expenses relating to the call connection. The provider of the service number can also be billed for the expenses arising from the call connection request.

The invention relates to a method for determining the quality of print quality. In the method, a first digital image, which represents the intended print quality in the graphical product, and a second digital image, which represents the achieved or planned print quality of the graphical product, are taken. After this, a variable proportional to the magnitude of the difference in the colour values of at least some image elements corresponding to each other in the image plane of the first and second digital images, is calculated, and on the basis of the variable, the similarity of the colour worlds of the first and second images is estimated. The invention permits the objective comparison of images, particularly in the development of print quality and in claims situations.
