Reconstruction of spine geometry using computed tomography and optical 3D scanner

design and construction of an optical computed tomography scanner for polymer gel dosimetry application

polymer gel dosimeter is the only accurate three dimensional (3d) dosimeter that can measure the absorbed dose distribution in a perfect 3d setting. gel dosimetry by using optical computed tomography (oct) has been promoted by several researches. in the current study, we designed and constructed a prototype oct system for gel dosimetry. first, the electrical system for optical scanning of the g...

3D reconstruction of lumbar vertebrae from computed tomography images

INTRODUCTION: Accurate 3D reconstruction of bony structures is essential for many clinical applications, such as evaluation of bone deformation, surgical planning and clinical follow-up of patients. Computed tomography (CT) is a widely used medical imaging technique in clinical routine, especially for bones which provide high contrast. However accurate bone segmentation still remains challengin...

diffuse optical tomography: image reconstruction and verification

introduction: in this study, we intend to use diffuse optical tomography (dot) as a noninvasive, safe and low cost technique that can be considered as a functional imaging method and mention the importance of image reconstruction in accuracy and procession of image. one of the most important and fastest methods in image reconstruction is the boundary element method (bem). this method is introdu...
