In this paper, we present an evaluation of seven automatic brain tissue classifiers based on level of agreements. A number of agreement measures are explained, and we show how they can be used to compare different segmentation techniques. We use the Simultaneous Truth and Performance Level Estimation (STAPLE) of Warfield et al. but also introduce a novel evaluation technique based on the Willia...

background: physical examination (pe) and breast mri are two of the current methods which have usually used in diagnosis of primary breast cancer. their accuracy in detection of: either complete response or presence of residual tumor, however, has not yet been established in patients who have been received neoadjuvant chemotherapy (nac). the purpose of this study was to evaluate the diagnostic ...

background: this study aimed to determine relationship between mri imaging results and demographic characteristics of patients with low back pain and lower extremity radiculopathy. methods: this analytic-comparative study was carried out from april 2007 until march 2008   on patient   referred to imam reza hospital in kermanshah. demographic features and mri imaging results of 242 patients with...

ARCHITECTING PROTOCOLS TO ENABLE MOBILE APPLICATIONS IN DIVERSE WIRELESS NETWORKS

In this paper, we consider the perfonnance of a cellular radio, : direct sequence, code division multiple access system. We analyze the performance of the mobile-to-base link, and we use a model corresponding to independent flat Rayleigh fading of each user.

Base stations represent the main contributor to the energy consumption of a mobile cellular network. Since traffic load in mobile networks significantly varies during a working or weekend day, it is important to quantify the influence of these variations on the base station power consumption. Therefore, this paper investigates changes in the instantaneous power consumption of GSM (Global System...

Increasing computing power in smartphones allows for their transformation into point-of-care diagnostic devices. Mobile medical diagnostic applications enable utilization of the processing capabilities of smartphones through their cameras. Hardware attachments or stand-alone versions of smartphone diagnostics have the capability to revolutionize quantitative readouts. Here, we describe a protoc...
