We evaluate the accuracy of whole-body bone extraction from whole-body MR images using a number of atlas-based segmentation methods. The motivation behind this work is to find the most promising approach for the purpose of MRI-guided derivation of PET attenuation maps in whole-body PET/MRI. To this end, a variety of atlas-based segmentation strategies commonly used in medical image segmentation...

For more clinical applications of deep learning models for medical image segmentation, high demands on labeled data and computational resources must be addressed. This study proposes a coarse-to-fine framework with two teacher student model that combines knowledge distillation cross teaching, consistency regularization based pseudo-labels, efficient semi-supervised learning. The proposed method...

we study umbilic (space-like) submanifolds of pseudo-riemannian space forms, then define totally semi-umbilic space-like submanifold of pseudo euclidean space and relate this notion to umbilicity. finally we give characterization of total semi-umbilicity for space-like submanifolds contained in pseudo sphere or pseudo hyperbolic space or the light cone.a pseudo-riemannian submanifold m in (a ps...

The aim of this paper is to introduce the notion of commutative pseudo BE-algebras and investigate their properties.We generalize some results proved by A. Walendziak for the case of commutative BE-algebras.We prove that the class of commutative pseudo BE-algebras is equivalent to the class of commutative pseudo BCK-algebras. Based on this result, all results holding for commutative pseudo BCK-...

Os autores fazem o relato de três casos clínicos: Papilomatose florida, Epitelioma cuniculatum e Condiloma gigante Buschke Lowenstein, considerados como representativos entidades que compõem grupo das Papilomatoses pseudo-carcinomatosas. São favoráveis à conceituação pseudo-carcinomatosas apoiando-se na semelhança clínica, histopatológica, evolutiva da terapêutica a ser instituída. Discutem, ai...
