Aim The purpose of the current paper is to present a computational solution to accurately quantify a specific to a non-specific uptake ratio in [123I] FP-CIT single photon emission computed tomography (SPECT) images and simultaneously measure the spatial dimensions of the basal ganglia, also known as basal nuclei. A statistical analysis based on a reference dataset selected by the user is also automatically per...
This paper proposes a fully automated computational solution to segment the incus and malleus ear ossicles in conventional tri-dimensional (3D) X-ray computed tomography (CT) images. The solution uses a registration-based segmentation paradigm, followed by image segmentation refinement. It was tested against a dataset comprising 21 CT volumetric images of the ear acquired using standard protocols and with resol...
O presente estudo identifica as espécies vegetais nativas utilizadas pelos moradores da Vila dos Pescadores localizada na RESEX Marinha Caeté-Taperaçu, em Bragança, Pará. Através de entrevistas baseadas em protocolos semi-estruturados realizadas com 30 moradores, foi traçado o perfil sócio-econômico dos entrevistados, identificadas as espécies vegetais úteis e seus respectivos usos. No total foram citadas 23 es...
