Abstract:

Introduction:
Throughout medical training we can find different areas. One of them is Human Anatomy, a course shared by many degrees in health sciences. The study of this topic has evolved over the years. Given the advance of knowledge and technology nowadays, the study is supported by different means such as radiological images, videos, podcasts, open access, scientific articles. Even with so, it is not always easy to understand all the elements of the anatomical structures and the relationships between them. Although current techniques have improved, they also have their limitations. That is why the advance in the development of new techniques helps and improves the quality of the studying. In this context, the aim of our study is to complete the education in the field of human anatomy by developing new tools for anatomical study. This tool is based on the creation of three-dimensional anatomical reconstructions through the post-process of radiological images. We will focus on the anatomical region of the orbit and visual pathway given the confluence of several structures (4 walls formed by 7 bones, 4 cranial nerves, among many others) and their interest in different medical specialities such as ophthalmology, otorhinolaryngology, neurosurgery, maxillofacial surgery.

Goals:
• Create three-dimensional anatomical models that facilitate the study of the structures of the orbit and visual pathway for both students and medical practitioners.
• Demonstrate the importance of integrating new technologies and the advantages they offer in the didactic field, including medical training as well as updating teaching methods in the field of Human Anatomy.
• Assess the possibility of other novel techniques or other protocols, such as 3D printing, based on three-dimensional anatomical models using radiological images.
• Analyse the different capacities presented by several software (Osirix, Amira, 3D slicer) comparing them to each other.

Material and methods:
Applied research; comparison, observation and analysis. We will three-dimensionally represent the components of the orbit and visual pathway from two-dimensional images obtained by different methods of diagnostic imaging: computerized tomography (TC) and magnetic resonance (RM). The devices we will use are: Helical TC General Electrics, Helical TC Philips, 1.5 teslas RM General Electrics, 1.5 teslas RM Phillips. We will use the images from the database of the radiodiagnosis service of the Complejo Asistencial Universitario de Salamanca and the Affidea center.

Results:
The three-dimensional vision has become a crucial tool for the learning and understanding of many complex anatomical structures such as the orbit, enabling the introduction of novel techniques for the teaching and learning of anatomical models.

Conclusions:
Our work aims to demonstrate the advantages of these new systems. Among them we can find: helpingin medical training, facilitating new study tools in this area, accessibility, morphological comprehension, improvement of spatial perception, establishing a better anatomo-radiological and clinical correlation, carrying out a wider differential diagnosis, possible application for the planning of technically complex surgeries, practicing surgical procedures on anatomical models before the patients themselves.
