摘要： Blur is one of the most important features related to image quality. Accurately estimating the blur level of an image is a great help to accurately evaluate its quality. A method for calculating blur of video images comprises calculating a horizontal blur value, and determining characteristic parameters of the video images, including at last progressive/interlaced and spatial resolution level. If the video images are progressive, also a vertical blur value is calculated, and combined with the horizontal blur value. The next step is normalizing the horizontal blur value, or the combined horizontal and vertical blur value, according to predefined min and max values, wherein the min and max values are adapted to the spatial resolution level.

摘要： A system and method for displaying MRI parameters measured from a tissue sample such a tumor. A computer system receives MRI data and determines a number of parameters including, a normalized cerebral blood volume (nCBV), a contrast transfer rate constant (kTrans) and apparent diffusion coefficient (ADC) calculated from Bo and B1000 MRI images for data points in the MRI data. These parameters are plotted onto a three-dimensional graph of voxels where the data in the MRI are mapped to a normalized radial distance and angle in the plot. The parameters nCBV, kTrans and 1/ADC are mapped to a color of the voxel and to height of a voxel in the +Z and −Z axes of the three dimensional plot.

摘要： The present invention provides methods for identifying agents capable of modulating RANK-mediated signaling pathways. The present invention also provides compositions and methods of using the same to treat osteoporosis or other RANK-related diseases. The present invention is based on the functional and structural analysis of three TRAF-binding motifs (PTM)—namely, PTM3, PTM5, and PTM6, each of which has been found to play a distinct role in the activation of RANK-mediated intracellular signaling. These PTMs can be used to screen for RANK modulators. These PTMs also represent potential drug targets for diseases that are associated with abnormal RANK expression or activity.
