These diagnostic techniques offer sections on colors, but do not allow to view images directly in three dimensions, so that we unite these brain structures in 3D images, indicates Juanes, which ensures that this new material for neuroscientists was impressive, since it assumed a very important contribution to know which anatomical structures were affected. The raw material is the radiological image and, from there, we rebuild what can do the unit, since there is no automatic segmentation, is the great challenge that we set, to get a MRI or CT scan computer to recognize a structure automatically and individualized, for example, that a bone appears only if it is the part that interests us. This is especially important in the case of the brain, since by its density do not allow to discriminate different structures. The researchers are working with DICOM images, a special format of teams of diagnostic imaging that is subsequently processed with software called Amira, the tool used for its reconstruction. Thus, we can read it, we do a mesh structure, give texture and this can embed inside the morphologic MRI, CT scan or in sections of the Visible Human project, explains. You can add to this information the mechanism of action of a drug, i.e., how it would act to treat certain diseases, which is analyzed with graphic animations based on real images. From the formative point of view they are a very didactic tools, but some have more relevant applications already used. For example, an anatomical Viewer for anaesthesia, developed recently, helps us in the operating room to locate a nerve and be able to anesthetize a zone, it indicates. In short, are open projects that can be applied to the study of pathology and treatment, which may be pharmacological and surgical. Viewers: similar work for multiple applications although anatomical viewers projects are diverse and encompass many different medical areas, share the same philosophy of facilitating learning through interactivity.
