Abstract: Systems and methods for correcting output signals from non-linear photosensors, specifically silicon photomultipliers (SiPMs). SiPMs are used in a PET detector to readout light emissions from LSO scintillator crystals. The non-linear output of the SiPM can distort and compress the energy spectrum which is crucial in PET imaging. The non-linearity effect for inter-crystal scattered events can place an energy event outside of the PET detector energy window, resulting in a rejected event. Systems and methods to correct the SiPM non-linearity for inter-crystal scattered events, so as to be able to obtain the proper energy event and produce an accurate medical image, are disclosed.

Abstract: The device enables the detection of positions of the navigation marking elements on a reference star by way of at least two projection images taken by an X-ray system at different pivoting angles of a C-arm. The positions of the navigation marking elements on the reference star are also calculated by a navigation system tracking camera. The transformation from the coordinate system of the navigation system into the coordinate system of the X-ray system is calculated from the position of the reference star detected by the X-ray system and the position of the reference star detected by the tracking camera. The navigation marking elements are located outside of the volume which is reconstructed by way of the imaging process in order to prepare tomographic images. The positions of the navigation marking elements are determined from two-dimensional projections. All the navigation marking elements need only be detected by at least two projection images.

The conductor and return conductor of the inductor lines are guided essentially vertically in the capping to the bottom of the deposit, at a small maximum lateral distance of 10 m compared to the length of the lines, but especially less than 5 m. Preferably, the inductor lines are guided horizontally in the deposit and are at different distances in certain areas. Furthermore, the electrical conductors and return conductors perpendicularly extending in the capping preferably combine to form a conductor pair. In this way, the conductor pair can be introduced into a single borehole which reaches into the reservoir and splits only once it has arrived in the reservoir.

Abstract: A generalized pattern recognition is used to identify faults in machine condition monitoring. Pattern clusters are identified in operating data. A classifier is trained using the pattern clusters in addition to annotated training data. The operating data is also used to cluster the signals in the operating data into signal clusters. Monitored data samples are then classified by evaluating confidence vectors that include substitutions of signals contained in the training data by signals in the same signal clusters as the signals contained in the training data.

A total penalty of the graph is minimized. A denoised image is provided based on the total penalty-minimized graph.
