the Shape and Motion of the Lungs and Heart in Dynamic Pulmonary Imaging
and ) between the blood and ambient air; therefore, adequate pulmonary ventilation (air flow) and perfusion (blood flow) are essential for the lungs to function properly. Inadequate pulmonary function may…
Detection of Lumbar Vertebrae in CT Spine Images
computed tomography (CT) images of the lumbar spine. The resulting mean symmetric absolute surface distance of mm and Dice coefficient of %, computed from the final vertebra detection results against…
Segmentation of the Thoracic and Lumbar Vertebrae
