EMVISION®

The software package by TechnoImaging® that allows for processing, 3D inversion and 3D modeling of all kinds of geophysical data. EMVision® makes it possible to transform data sets of any size, including extremely large surveys, with the option of the integration and joint inversion of different types of geophysical data.

EMVision® features the following:

  • High stability and accuracy in 3D modeling with the suite of numerical methods, including integral equation, finite difference, and finite element techniques

  • Large-scale 3D inversion with fine grids by using the moving sensitivity domain approach

  • Integrated geophysical model based on multimodal geophysical data with joint 3D inversion using Gramian and joint focusing constraints 

  • Sharp, focused images with 3D focusing regularization

  • Parallelized and optimized for the in-house powerful TechnoImaging®’s PC cluster
