Structure Function Estimated from Histological Tissue Sections |pdf=|usr=}}{{27046871}} gab.com Text Structure Function Estimated from Histological Tissue Sections JO: IEEE Trans Ultrason Ferroelectr Freq Control http://www.kidney.de/pget.php?&tw=1&pmid=27046871 #FOAvip Ultrasonic scattering is determined by not only the properties of individual scatterers but also the correlation among scatterer positions. The role of scatterer spatial correlation is significant for dense medium, but has not been fully understood. The effect of scatterer spatial correlation may be modeled by the structure function as a frequency-dependent factor in the backscatter coefficient (BSC) expression. The structure function has been previously estimated from the BSC data. The aim of this study is to estimate the structure function from histology to test if the acoustically estimated structure function is indeed caused by the scatterer spatial distribution. Hematoxylin and eosin stained histological sections from dense cell pellet biophantoms were digitized. The scatterer positions were determined manually from the histological images. The structure function was calculated from the extracted scatterer positions using two-dimensional fast Fourier transform. The structure function obtained from histology showed reasonable agreement in the shape but not in the amplitude, compared with the structure function previously estimated from backscattered data. Fitting a polydisperse structure function model to the histologically estimated structure function yielded relatively accurate cell radius estimates (error < 15%). Further, two types of mouse tumors that have similar cell size and shape but distinct cell spatial distributions were studied, where the backscattered data were shown to be related to the cell spatial distribution through the structure function estimated from histology. In conclusion, the agreement between acoustically estimated and histologically estimated structure functions suggests that the acoustically estimated structure function is related to the scatterer spatial distribution. 1 Twit Text FOAVip Structure Function Estimated from Histological Tissue Sections ????IEEE Trans Ultrason Ferroelectr Freq Control http://www.kidney.de/pget.php?&tw=1&pmid=27046871 #FOAvip Twit Text # Free Paper on # # # # # LINK http://www.kidney.de/pget.php?&tw=1&pmid=27046871 #FOAvip English Wikipedia <ref>{{Cite pmid|27046871}}</ref> Structure Function Estimated from Histological Tissue Sections #MMPMID27046871 Han A; O'Brien WD IEEE Trans Ultrason Ferroelectr Freq Control 2016[Sep]; 63 (9): 1296-305 PMID27046871show ga Ultrasonic scattering is determined by not only the properties of individual scatterers but also the correlation among scatterer positions.
