20100176301 | HIGH RESOLUTION MEDICAL IMAGING DETECTOR - A detector arrangement providing imaging information at the edge of the scintillator is provided. The detector arrangement provides complete information and improved spatial resolution. SiPMs can be used in place of PMTs in order to provide the geometrical coverage of the scintillator and improved spatial resolution. With such detector arrangements, the spatial resolution can be under 2 mm. Furthermore, the overall thickness of the detector can be substantially reduced and depth of interaction resolution is also improved. | 07-15-2010 |
20110007958 | APPARATUS AND METHOD FOR GENERATION OF ATTENUATION MAP - A method of image reconstruction corrected for attenuation is provided for use with radioemission-based imaging, such as SPECT and PET. This method includes collecting measured emission projection data. The emission projection data, a reconstruction of the emission projection data, and a priori organ information are collectively analyzed to generate a body region estimate of the imaged subject. Each voxel of the body region estimate is then homogenously assigned an attenuation coefficient to generate an initial attenuation map estimate. An initial emission assumption is also generated based on a reconstruction of the emission projection data. The initial emission assumption and initial attenuation map estimate are then processed and refined to produce an image reconstruction. | 01-13-2011 |

20130142411 | DUAL MODALITY IMAGING INCLUDING QUALITY METRICS - An anatomical image data set and an emission image data set are acquired for a subject. An attenuation map is generated from the anatomical image data set. The emission image data set is reconstructed to generate an emission image. The reconstructing includes correcting for attenuation of emission radiation in the subject using the attenuation map. A value is calculated for a quality assurance (QA) metric quantifying alignment of the attenuation map with the emission image. The emission image is displayed or printed together with the calculated quality assurance metric. In some embodiments, prior to the reconstructing the attenuation map is registered with the emission image data set by performing a global rigid registration followed by a local non-rigid registration of a region of interest. | 06-06-2013 |

20100046817 | CARDIAC SPECT SYSTEM WITH TRAJECTORY OPTIMIZATION - In a disclosed imaging method, the instantaneous speed or data acquisition dwell times of a detector head ( | 02-25-2010 |
20120205542 | CARDIAC SPECT SYSTEM WITH TRAJECTORY OPTIMIZATION - In a disclosed imaging method, the instantaneous speed or data acquisition dwell times of a detector head is optimized as a function of position along a path of the detector head around a subject. The optimization is respective to an expected radioactive emission profile of a region of interest that is less than the entire subject. The detector head is traversed along the path using the optimized instantaneous speed or data acquisition dwell times. During the traversing, imaging data are acquired using the detector head. The acquired imaging data are reconstructed to generate a reconstructed image of at least the region of interest. A gamma camera configured to perform the foregoing imaging method is also disclosed. | 08-16-2012 |

20100098956 | Coating Material for Protecting Metals, Especially Steel, From Corrosion and/or Scaling, Method for Coating Metals and Metal Element - The invention relates to a coating material for protecting metals, especially steel, from corrosion and/or scaling, to a method for coating metals and to a metal element. The aim of the invention is to provide a coating material that protects steel from corrosion and/or scaling and that can be welded after heat treatment of the coated steel at temperatures of more than 800° C. For this purpose, substances are provided that render the applied coating material suitable for welding, especially for spot welding. The coating material can be applied by wet chemical methods, it changes its structure when subjected to high temperature processes of more than 600° C. and is suitable as a primer for additional coating materials. It was surprisingly found that when a suitable binder including a suitable filler is used during the high temperature treatment of a curing process, the coating materials of the invention change in such a manner that electrically conducting reactive layers are formed that allow welding and especially spot welding together with the metal substrate even after treatment at temperatures of more than 800° C. | 04-22-2010 |

20120009340 | METHOD FOR PRODUCING DEFORMABLE CORROSION PROTECTION LAYERS ON METAL SURFACES - The invention relates to a method for producing deformable corrosion protection layers on a metallic surface and to use of the method. In order to create an economical process for cathodic corrosion protection of metal for a broad range of applications, the invention proposes a method for producing deformable corrosion protection lavers on a metallic surface, consisting of the following steps: a) Mixing 5 to 95 wt. % metallic magnesium, zinc, aluminum or titanium particles, or mixtures or alloys containing at least one of these metals, in the form of pigments, powders, pastes (flakes) or pellets with 5 to 95 wt. % of at least one metal compound, wherein a reaction between the metal particles and metal compound(s) results in surface-modified metal particles; b) Applying the resulting surface-modified metal particles to the metallic surface; c) Hardening the layer produced from the surface-modified metal particles at temperatures between room temperature and 350° C. It has been shown within the context of the invention that the metal substrate coated according to the method of the invention can be deformed, overpainted, welded, coated and colored, and reflects heat. | 01-12-2012 |

20100166536 | Apparatus for the separating of stacked plate-shaped elements - The invention relates to an apparatus for the separating of stacked plate-shaped elements. It is the object of the invention to provide possibilities with which stacked plate-shaped elements, in particular plate-shaped elements prone to breakage, can be reliably separated in a short time and to increase the useful operating time of an apparatus. In the invention, a stack of plate-shaped elements is placed onto a lifting device with which a stepped raising in vertical stages takes place. A conveying device for plate-shaped elements is arranged above the stack, with at least one conveying element being fastened to a conveyor belt made in the form of a continuous conveyor or to at least one rotating roller at said conveying device. Conveying elements are made from an elastically deformable material and have at least one end face in the direction of the surfaces of plate-shaped elements to be separated. | 07-01-2010 |
