20140119627 | Method for improved estimation of tracer uptake in physiological image volumes - A method of estimating the true uptake of a tracer in a physiological image acquired with a physiological image modality that has limited spatial resolution comprises: co-registering an anatomical image volume and the physiological image volume such that both image volumes have corresponding voxels; segmenting the anatomical image volume into a number of non-overlapping anatomical regions; combining each of the segmented anatomical regions with a function representative of the limited spatial resolution of the physiological image modality to generate a blurred anatomical region volume for each of the segmented regions; assuming the physiological image in each voxel to be a linear sum of the image intensities of the corresponding voxels in the blurred region volumes in that voxel; estimating, for each voxel, a value representative of the contribution to that voxel from each blurred region volume based on the uptake measured by the physiological image for that voxel and for nearby voxels; and using the estimated values for the voxels to estimate a true uptake of the tracer in each voxel and to thereby establish a corrected physiological image volume. | 05-01-2014 |

20120185600 | Control of Codec Negotiation for Communication Connection - The invention relates to a session control entity, method and a computer program product for receiving a request for a session, deciding on removal of a user plane gateway from a user plane of the session, extracting, when the user plane gateway is to be removed, a first codec list in the second encoding and removing the first codec list from the request for the session. Further, removing a second codec list in the first encoding from the request for the session, deriving a third codec list, when the user plane gateway is to be removed, from the first codec list, or, when the user plane gateway is not to be removed, from the second codec list, including in the request for the session, a third codec list in the first encoding, and transmitting the request for the session. | 07-19-2012 |
