Background Traditionally, embryo incubation and assessment daily has been under a light microscope, these observations are inevitably restricted to specific times and considering that the development of the embryo is a dynamic process, several critical stages in between observations may go unnoticed. For this reason, the new technologies, time lapse monitoring, have focused on the research for ...

Dynamic imaging provides an effective way to integrate previous surveys seismic data in order to estimate current velocity model. It is particularly useful for time-lapse imaging, which has been successfully applied to reservoir monitoring over the years by oil industry and developed for CO2 sequestration monitoring more recently. This work aims to introduce a new dynamic imaging method for per...

Ž . Ž . Four-dimensional 4D or time-lapse three-dimensional 3D ground penetrating radar surveys can be used to monitor and image subsurface fluid flow. This information can be used to create a model of hydrogeological properties. The massive amount of data, which is present in and can possibly be generated from 4D GPR data sets, precludes a manual interpretation. Consequently, 4D data sets have...

The development of an organism consists of processes occurring in space and time. To analyze this 4-dimensional development in embryogenesis, an appropriate method should be chosen. We present here a sophisticated method, 4D microscopy (3D time-lapse microscopy), initially developed to analyze the cell lineage of wild-type and mutant embryos of the nematode Caenorhabditis elegans. Our method re...
