purpose t1wi (t1 weighted image) was acquired in order to grade bone fusion following the studies by fifa (federation internationale de football associations). research using images other than t1wi has not been reported. the aim of this study is to evaluate the grade of epiphyseal fusion by t2* weighted images (t2*wi) and to investigate new findings on t2*wi as compared with t1wi. methods a tot...

A method for optimizing MR imaging pulse sequence parameters in a statistical framework is presented. Parameters are defined to be optimal when the resulting scalar images yield optimal image segmentations using Bayesian pixel classification. Thus, Bayes risk is used as the objective function to minimize. Approximations are made to give a tractable solution in a four-step procedure. A sample ca...

ADAPTIVE SPACE-TIME PROCESSING FOR DIGITAL MOBILE RADIO COMMUNICATION SYSTEMS

introduction: it has been shown that joint click, an initial and common finding in internal derangement (id), respond to neither conservative treatment nor surgical intervention. this raises the question as to whether it must be treated in the absence of other pertinent signs and symptoms, so the aim of this study was to investigate and compare the mri findings of tmj in both normal subjects an...
