چکیده

Anisotropy measurements of 15 trabecular bone biopsies from the radius estimated by different fabric tensors on images acquired through cone beam computed tomography (CBCT) and micro computed tomography (micro-CT) are compared. The results show that the generalized mean intercept length (MIL) tensor performs better than the global gray-scale structure tensor (GST), especially when the von MisesFisher kernel is applied. Also, the generalized MIL tensor yields consistent results between the two scanners. These results suggest that this tensor is appropriate for images acquired in vivo through CBCT.

مقایسه دقت توموگرافی سه‌بعدی با اشعه مخروطی با توموگرافی کامپیوتری مرسوم در تشخیص بیماری‌های سینوس پارانازال

Background: Paranasal sinus disease is one of the most common problems of patients that refer to ENT centers. Adding to clinical examination imaging plays an important role in diagnosis and treatment. Also the imaging of paranasal sinuses is necessary before surgery. Although computed tomography is the modality of choice for these areas, it has some disadvantages which the most important one is...

Prediction of apparent trabecular bone stiffness through fourth-order fabric tensors.

The apparent stiffness tensor is an important mechanical parameter for characterizing trabecular bone. Previous studies have modeled this parameter as a function of mechanical properties of the tissue, bone density, and a second-order fabric tensor, which encodes both anisotropy and orientation of trabecular bone. Although these models yield strong correlations between observed and predicted st...
