ABSTRACTThe emergency of consciousness continue to be open challenge the scientific community. Tools such as diffusion weighted imaging (DWI) and tractography try to settle this debate by showing the processes at the biological level of the a conscious states. Even...

A deep learning approach for automatic segmentation of ground-glass opacities and consolidation in small Chest-CT dataset

por jorge boada | Abr 12, 2022 | Documentos de investigación

ABSTRACTGround-glass opacities (GGO) and consolidation are findings typically observed in pneumonia and other acute lung diseases. For radiologists, segmentation and analysis of GGO and consolidation on chest computed tomography (CT) images are critical to quantify...
