Stereoscopic and autostereoscopic techniques are widely used in numerous scientific applications. Imaging techniques such as radiography, ultrasound, computerized tomography (CT) and magnetic resonance imaging (MRI), have gained considerable importance in the field of medicine, where it is used to study organs or organisms in vivo with techniques that allow us to study the inside of the body without intervention. Imaging also plays an important role in biochemistry, where it is used for molecular modeling. Scientific visualization is concerned about the presentation of concrete data with an intrinsic representation. This chapter talks about the ways in which stereoscopic capacities can vastly improve biomedical imaging and molecular graphics; the applications for hospital practitioners for teaching, diagnosis and patient treatment, and for biochemists to achieve a clearer structural understanding of the macromolecules which they study.
