Abstract
    In this chapter we describe computer-based tomographic methods using magnetic resonance imaging (MRI) and X-ray absorption as well as X-ray phase-contrast imaging techniques. The latter are based on refraction and near-field diffraction of X-rays and are gaining increased attention due to the increase in sensitivity they offer over conventional, attenuation-based X-ray techniques. The increased sensitivity is of particularl interest in marine biology imaging, especially for soft tissue visualization and analysis. The basic principles of the imaging formation process, followed by a review of several tomography methods, such a MRI or X-ray imaging, and practical guidelines for parameters selection. Finally, two relevant examples of imaging are presented: imaging in marine biology (segmentation and visualization) and small animal (sea horse) imaging. These examples illustrate imaging under different conditions and using the different reconstructrion options.
