Introduction

The fundamental pillar of patho-anatomical education (in addition to lectures and illustrated textbooks) is laboratory dissections still to date. But handling of cadaver the litigations related to funeral rights prompted more and more medical teaching institutions to look for alternative means of education to teach anatomy.

The opportunity for medical students in the cadaver dissection lab is limited to few hours a week. This short time frame is insufficient to validate their knowledge with reality and compare the human model they built to what they built in their mind by reading illustrated textbooks or using other means of education.

Increased demand of education tools and the rapid development of computer science resulted in more sophisticated computer applications for anatomy education. Universities prefer to use novel technologies and create digital content which is easily accessible and editable.

Rare patho-anatomical specimens are only visible at museums thus they are not commonly accessible and not presented in common curriculum and thus, no chance for in depth study. These  cases are only presented in the marginal notes of textbooks. However the knowledge of such rare diseases are mandatory in medical education.

Our goal will be to scan with the Neuro-Arc Imaging System, 20 Pathology specimens from the Semmelweis University Museum, enable students and teachers to study the intricate details of rare specimens, and enhance the reputation of Semmelweis University across the Globe.

 Image reconstruction

Existing 3D, CT, MR technologies and special methods such as 3D DSA to examine the vascular architecture, created opportunity for object rotation and manipulation. Rotation offers enhanced visualization and additional information as compared to static 2D imaging.

Hidden structures may become visible , however major disadvantages of these imaging methods is that their appearance looks artificial in terms of display and do not reflect true color texture and shadows.

On the other hand photography based imaging was only available in 2D format. No interaction was provided up until recently. Photographic image manipulation was not available and invisible structures were not be able to be seen due to the lack of rotation.

4D Anatomy technology offers enhanced visualization, provides advanced image manipulation and navigation to simulate anatomic dissections and surgical procedures. The patented technology consist a spatial scanner which provides photographic images at any point of a spherical scan around the object. Image reconstruction offers enhanced 4D display thus reconstructs dissection in a virtual fashion.

Images of the image grid was captured in spherical manner around the object at the same focal point thus each image displays the same focal point from a slightly different angle.

During dissection process the specimen is kept in position, repeated scanning results multilayered image grid. Each element of these grids shows the same focal point from multiple angles at various stages of dissections. The entire multilayered imager grid system is later reconstructed into a single interactive multidimensional montage. The specimens are subject to rotation, tilting, panning, and zooming. Layering shows the actual steps of simulated surgical or dissection process. Users are able to virtually grab and study the specimen rotate and tilt it to any selected angle.

The image shows the actual effect of rotation as the pituitary stalk becomes visible as the specimens is rotated. A.c.i.: Arteria cerebri interna, L.t.: Temporalis lebeny L.f.: Frontális lebeny, S.: Sylvius árok, N.o.: Nervus opticus

The picture shows the effect of layering. Two images show consecutive stages of dissections but at the same spatial orientation. Notice as removal of the optic nerve the pituitary stalk becomes visible.

Project

Technology background

20 e-Learning syllabus to be developed by using the interactive multidimensional imager reconstruction technology of 4D Anatomy. (www.4danatomy.com)

The technology includes robotic equipment and related image reconstruction application which enables the to create interactive 4 dimensional modular e-Learning education material.

This unique technology provides full image manipulation and navigation features. It also offers users to virtually grab the specimen navigate to any selected angle view and manipulate the specimens form various spatial orientations. Layering offers pealing away layers of anatomy to reveal otherwise hidden elements. The application provides an unprecedented life-like environment of lab dissections anytime reproducible fashion.

The interactive multidimensional modular montages are enhanced with multimedia elements such as images, videos, illustrations and notes to create  a comprehensive eLearning material. to support education.

Interactivity helps comprehension of the complicated 3d dimensional architecture of the human body as opposed to simple video recordings which requires passive viewing. Animation recently used for anatomy education has artificial appearance just like drawings and illustrations. Animation  doesn’t reflect true color and texture and is not able to provide details that photography is able to display. According to surveys education tools containing photographic imaging is far superior and preferred to animated or illustrated ones.

4D anatomy software is fare superior in terms of portraying and effectively communicate the complexity of anatomy as opposed to illustrated textbooks which is difficult to assemble the complex 3D model of the human body.

Therefore the new innovative 4D Anatomy technology overcomes these limitations and being able to provide a photographic environment in an interactive and anytime reproducible fashion will captivate students and teachers interest and enhance their learning.

Goals and results

Long term aims and results

  • To strengthen reputation of Hungarian medical education which is well recognized all around Europe by further elevating standards of education.

Result: number of foreign student will increases by 10% in 5 years.

  • Increasing efficacy of diagnosis by higher level medical education. This cost-effective opportunity doesn’t assume installation of diagnostic tools in healthcare supply system.

Result: Number of misdiagnosis will reduce with 1% in 20 years.

  • Time lost from work will be reduced, time of patient care is reduced as the results of faster diagnosis and targeted treatment process.

Result: Number of sick days are to be reduced by 1% in 20 years.

Immediate goals of the project

  • to apply a globally unique Hungarian Innovation a patented IT technology (4D Anatomy) for medical training and to develop related educational methodology, and digital curricula.
  • to create and enhance individual, independent student work, and opportunities to work in study groups.
  • to define educational methodology of this unusual approach, which focuses on a specific disease in simultaneous but multidisciplinary approach (pathology, anatomy, radiology, clinical relevance) within the same curriculum.
  • trainings to be held by well prepared teachers possessing advanced IKT competencies.
  • to create training materials by the administration of this novel technology and related methodology which can be easily accessible, continuously updated, containing 06modern multimedia enhanced digital 06content.
  • to create flexible training procedures.
  • to develop training content attractive for international students as well.
  • to provide life-long learning opportunities and incorporate the material into the curricula for post-graduate training to achieve strategic requirements by making it available in modular fashion.
