We use integral images of a three-dimensional (3D) scene to estimate the longitudinal depth of multiple objects present in the scene. With this information, we digitally reconstruct the objects in three dimensions and compute 3D correlations of input objects. We investigate the use of nonlinear techniques for 3D correlations. We present experimental results for 3D reconstruction and correlation...

normal 0 false false false en-us x-none ar-sa digital breast tomosynthesis (dbt) is a technology that creates three dimensional (3d) images of breast tissue. tomosynthesis mammography detects lesions that are not detectable with other imaging systems. if image reconstruction time is in the order of seconds, we can use tomosynthesis systems to perform tomosynthesis-guided interventional procedur...

We demonstrated a three-dimensional (3D) dental scanning apparatus based on structured illumination. A liquid lens was used for tuning focus and a piezomotor stage was used for the shift of structured light. A simple algorithm, which detects intensity modulation, was used to perform optical sectioning with structured illumination. We reconstructed a 3D point cloud, which represents the 3D coord...

In order to perform intra-operative or post-implant dosimetry in prostate brachytherapy, the 3D coordinates of the implanted radioactive seeds must be determined. Film or fluoroscopy based seed reconstruction techniques use back projection of x-ray data obtained at two or three x-ray positions. These methods, however, do not perform well when some of the seed images are undetected. To overcome ...

Deconvolution of three-dimensional (3D) fluorescence microscopy images using computational restoration algorithms may be seen as a cheaper alternative to modern 3D microscopy techniques. We have recently developed a digital deconvolution microscope based upon a standard upright fluorescence microscopy setup, which allows us to perform precise optical-sectioning procedures by positioning the sam...
