  • The impact of robotics on neurosurgery

    Stuart Campbell, Clinical Sales Development Manager of the Neurological Products Division at Renishaw, discusses key trends on the use of robotics in neurosurgery. The curious case of Phineas Gage is one of the earliest and best known cases of serious brain injury. On September 13th, 1848, Gage was working as a railway foreman in Vermont when an explosion caused a three foot long iron rod to be ...

  • Virtual 3D reconstruction, diagnosis and surgical planning with Mimics software

    CT scans interpretation is no longer strictly related to the machine. They can be analysed with specialised software that allows for diagnosis, surgical and dental procedures planning. So, medical doctors can analyse and determine the step–by–step procedure in the actual phase with a computer. There are presented some real examples computed with Mimics software. Keywords: CT scans, 3D ...

  • Three–dimensional seismic tomography with tetrahedra element on isoparametric mapping

    The author has developed a method of three–dimensional seismic tomography on concrete structures. This method is based on ray–trace and identification technique, and the distribution of slowness or energy dissipation is identified based on simultaneously iterative reconstruction technique (SIRT) or the other kind of statistical identification technique. This kind of technique was originally ...

  • Vision-based 3D surface motion capture for the DIET breast cancer screening system

    Breast cancer is one of the most prevalent forms of cancer in the world today. The search for effective treatment and screening methods is a highly active area of research. The Digital Image-based Elasto-Tomography (DIET) project is a new breast cancer screening system under development, where surface motion from the mechanically actuated breast is measured in 3D, and used as input to an inverse ...

  • Small scale mechanical properties of polycrystalline materials: in situ diffraction studies

    The recent developments in the fields of processing, mechanical characterisation as well as simulation allow for a deeper study of the relationships between the microstructure and the mechanical properties of nanostructured materials (thin films and bulk nano materials). The understanding of size effect on the elastic and plastic deformation mechanisms is of both fundamental and practical ...

  • Atomic resolution analyses of nano-structured materials by atom probe tomography

    The three dimensional atom probe (3DAP) is a well established and widely used nanoanalysis tool in materials science (mainly metallic materials). Due to its ability to map out in 3D the distribution of atoms in the real space on a nearly atomic scale, it has been extensively applied for the investigation of a large variety of materials, allowing a better understanding of physical phenomena ...
