20100130190 | Method for Controlling the Synchronization in a Communication System Covering at Least One Cell for Wireless Communication With a Line-Limited or Across-Line Wireless Direct Communication Possibility Between Mobile Parts That is Synchronized with a Base Station - In order to prevent in a communication system covering at least one cell for wireless communication, the system having a line-limited or across-line wireless direct communication possibility between mobile phones that is synchronized with a base station, that mobile parts attempt to synchronize in the communication system with a continuous broadcast downlink service provided by a hybrid mobile part, it is proposed to mark the continuous broadcast downlink service of the hybrid mobile part, which assumes the role of a radio fixed part, so that mobile parts, which want to synchronize with a true radio fixed part, can detect that the service provided by the hybrid mobile part is not permanently available, or even incomplete. | 05-27-2010 |
20100272095 | Device and Method for Controlling the Creation of a User Channel Connection in a Communication System and Associated Communication System, Digital Storage Medium, Computer Program Product, and Computer Program - In order to be able to control the creation of a user channel connection in a communication system using wireless communication between at least one mobile part and one wired part in such a way that a user channel connection is established more quickly upon a connection request indicated by the mobile part or the wired part for the purpose of transmitting user data and, at the same time, due to market requirements, no synchronization pulses are sent by the wired part in the idle state, an initiating device of the communication system (for example, for an incoming call: base station; for an outgoing call: mobile part) sends, from an asynchronous idle state, synchronization pulses (SB) to all available physical resources. Due to the plurality of the sent, available synchronization pulses (SB), rapid synchronization is ensured because the probability is sufficiently increased thereby that a pulse will fall in the search window of a receiver. | 10-28-2010 |

20080217540 | Incorporation of axial system response in iterative reconstruction from axially compressed data of cylindrical scanner using on-the-fly computing - A method and system for reconstructing PET image data from a cylindrical PET scanner by incorporation of axial system response. The method includes the steps of: assuming the decomposition of axial components into individual line-of-response (LOR) contributions, approximating each LOR spreading in image space as depth-independent, implementing each LOR response, combining the LORs to produce large span projection data, implementing the back projector as a transposed matrix, and assembling the LOR projections and spans for each azimuthal angle. | 09-11-2008 |
20080219525 | Acceleration of Joseph's method for full 3D reconstruction of nuclear medical images from projection data - A method for interpolating at least one oblique line of response ray representing nuclear image projection data through a rectangular volume and a system for using the method. The method consists of steps of interpolating all the direct rays in a rectangular volume, making a projected ray by projecting the oblique ray onto a surface of the rectangular volume, matching the projected ray to a coinciding interpolated direct ray, shearing the rectangular volume to match the projected ray, and interpolating the oblique ray in the sheared volume. | 09-11-2008 |
20140056500 | Generating Attenuation Correction Maps for Combined Modality Imaging Studies and Improving Generated Attenuation Correction Maps Using MLAA and DCC Algorithms - The DCC (Data Consistency Condition) algorithm is used in combination with MLAA (Maximum Likelihood reconstruction of Attenuation and Activity) to generate extended attenuation correction maps for nuclear medicine imaging studies. MLAA and DCC are complementary algorithms that can be used to determine the accuracy of the mu-map based on PET data. MLAA helps to estimate the mu-values based on the biodistribution of the tracer while DCC checks if the consistency conditions are met for a given mu-map. These methods are combined to get a better estimation of the mu-values. In gated MR/PET cardiac studies, the PET data is framed into multiple gates and a series of MR based mu-maps corresponding to each gate is generated. The PET data from all gates is combined. Once the extended mu-map is generated the central region is replaced with the MR based mu-map corresponding to that particular gate. On the other hand, in dynamic PET studies the uptake in the patient's arms reaches a steady state only after the tracer distributes throughout the body. Hence, for dynamic scans, the projection data of all frames is summed and used to generate the MLAA based extended mu-map for all frames. | 02-27-2014 |
20150289832 | Multi-Bed Elastic Motion Correction - A set of first modality data (e.g., MR or CT) is provided. The set of first modality data comprises a plurality of mu-maps, a plurality of motion vectors and a plurality of gated data. Each of the mu-maps corresponds to one of the beds. A set of second modality data (e.g., PET/SPECT) is provided. The set of second modality data comprises a plurality of frames for each of the beds. Each of the plurality of frames is warped by one or more motion vectors of the plurality of motion vectors. A single-bed image is generated for each bed by summing the frames corresponding to the bed. A whole body image is generated by summing the single-bed images for each of the beds. | 10-15-2015 |
20150302613 | Method To Compensate Gating Effects On Image Uniformity And Quantification For PET Scan With Continuous Bed Motion - Methods and systems for processing data for medical imaging are disclosed. The method includes obtaining a set of continuous bed motion (CBM) data from a first imaging modality. The set of CBM data includes a plurality of gating signals. A CBM normalization matrix is calculated. The CBM normalization matrix calculation includes the plurality of gating signals. An image is reconstructed from the CBM data and the CBM normalization matrix. The first imaging modality can be a PET imaging device. | 10-22-2015 |
