Abstract
Влияние конволюционных ядер и эффекта «упрочнения луча» на оценку минеральной плотности губчатой костной ткани с использованием количественной компьютерной томографии
Highlights
Quantitative computed tomography (QCT) along with dual energy x-ray absorptiometry (DXA) are used to assess mineral density and strength of bone tissue
When performing computed tomography (CT), the projections of the scanned object using the reconstruction kernel are converted into a series of images
This paper investigated the influence of various effects and CT scanner settings on Hounsfield units (HU) of trabecular bone tissue samples and K2HP O4 samples with known mineral density
Summary
Quantitative computed tomography (QCT) along with dual energy x-ray absorptiometry (DXA) are used to assess mineral density and strength of bone tissue. When performing computed tomography (CT), the projections of the scanned object (synograms) using the reconstruction kernel are converted into a series of images. The result is parallel slices located at equal distances from each other These data are converted by means of convolution kernels. Convolution kernels are used to achieve greater visual expressiveness of objects on the tomogram. In other words, they are needed for a more detailed and informative presentation of objects of a certain density range.
