The invention relates to a belt conveyor which comprises a conveyor belt (20) that is guided around at least one return shaft (30), thereby forming an upper run and a lower run, and a drive device for moving the conveyor belt (20), characterized in that the drive device is preferably arranged in a separate manner from the return shaft (30) and drives the conveyor belt (20) in the area of a deflection between upper run and lower run. The drive device preferably comprises a toothed belt (40) or V-belt arranged at an edge section of the conveyor belt (20) and a rotationally drivable toothed wheel (60) or a V-belt disk. The toothed belt (40) or V-belt is connected or connectable, preferably in a releasable manner, to the conveyor belt (20).

In the CT imaging of non-homogeneously moving objects such as the heart or the coronary vessel tree, there is a problem that different parts of the objects are at rest at different points in time. Thus, a gated reconstruction with a globally selected time point does not yield a sharp image of such objects. According to the present invention, a motion of the objects is estimated, describing the motion of selected regions of these objects. Then, on the basis of the estimated motion, time points are determined, where these areas have minimal motion. Then, an image is reconstructed, wherein the data from which the respective regions are reconstructed, correspond to the respective time points, where the regions have minimal motion. Due to this, an improved image qualify maybe provided.

Systems and methods for playing live casino games. The systems have changeable displays which portray virtual playing cards or symbols to live participants. Shuffling, cutting, dealing and return of playing cards are accomplished using data processing functions within an electronic game processor or processors which enable these functions to be performed quickly and without manual manipulation of playing cards. The invention allows casinos to speed play and reduce the risk of cheating while maintaining the attractive ambiance of a live table game. The systems can also be multi-user slot machines using the processor to associate or assign one or more symbols either with the virtual playing cards or as slot symbols in participant subsets. The participant subsets are compared to a predetermined list so that payoffs can be awarded on the basis of winning symbols or combinations of symbols.

The present invention provides an automated settlement system and method for receiving appropriate information, monitoring and controlling the timely interaction between the participants to settle trade and to guarantee the irrevocable and inseparable exchange of cash against securities. Two market participants which have agreed to exchange securities against cash forward their request to the automated settlement system of the present invention. The settlement system takes over control of the further procedure by initiating and monitoring a timely transfer of cash to a trust account, initiating and monitor the transfer of securities from the seller's securities deposit account to the buyer's securities deposit account, and to finally credit the seller's cash account. The central settlement system is responsible for involving and processing the interactions between the market participants, the custodians/((I)CSDs) and cash correspondent banks.

The invention relates to a method of navigating a magnetic object (11) within an object (1) which is exposed to a magnetic field, as well as to a magnetic resonance device in which this method can be carried out. The method according to the invention is particularly suitable for navigating a catheter or a flexible endoscope within the body of a patient. The magnetic object (11), preferably being provided in or on such a medical instrument (10), has a controllable magnetic moment for this purpose and the direction of movement of the object is determined by control of the magnetic moment. In the case of a magnetic resonance device whose static magnetic field is used, the object (11) is preferably includes as a coil system.

The invention relates to a magnetic resonance tomography method where a plurality of sequences act on an object to be examined in the presence of a steady, uniform magnetic field, each of said sequences including the generating of a magnetic rf pulse in conjunction with a first magnetic gradient field and the reading of a spin resonance signal in the presence of a second magnetic gradient field having a gradient extending perpendicularly to the gradient of the first field, an image of the nuclear magnetization distribution being reconstructed from the spin resonance signals by Fourier transformation. In order to produce a survey image therefrom in an as short as possible period of time, the object to be examined is displaced during the examination in the direction of the gradient of the first magnetic gradient field, the image of the nuclear magnetization distribution being line-wise reconstructed by way of a one-dimensional Fourier transformation of the spin resonance signal each time obtained.

A scanner (10) is used to provide images for automated diagnoses of neurodegenerative diseases, such as Alzheimers disease. The images are registered (90) to a template (78). The aligned image is analyzed (60) in relation to reference image data (76, 80) which has been registered to the template which is contained in a knowledge maintenance engine (70) for similar patterns of hypo-intensity that would indicate (in the case of an FDG tracer) reduced glucose uptake in the brain. The most appropriate reference images for the analysis of the present study are chosen by a filter (74). The present study is then given a dementia score (84) as a diagnostic feature vector that indicates to a clinician the type and severity of the ailment based on the analysis. The scanner (10) can produce PET or other metabolic and MR images for diagnosis. The MR can be used to measure blood flow rate into the brain. From the blood flow rate and the metabolic image, tracer, e.g. FDG, uptake maps can be generated for use in the automated diagnoses.
