The vertebra and muscles of the upper arm

The task was to create realistic 3D models of the vertebra and muscles of the upper arm. A number of techniques were employed to achieve the final result. The techniques include retopology (in the case of the vertebra) and modelling using primitive shapes, which were modified in order to create organic shapes while keeping the mesh tidy. Textures were later applied to both models using UV mapping technique.

The modelling, lighting and animation processes were completed in 3DS Max. The video was then composed in Adobe After Effects.

Volumetric Visualisation

Visualisations of the medical datasets (CT and MRI) produced by using direct and indirect volume rendering techniques.

Fractured Pelvis

Direct Visualisation of the Fractured Pelvis After Operation

Direct Volume Rendering of the Tooth

Direct Volume Rendering of the Tooth

The anatomy of the tooth can be observed due to lowered opacity of the enamel and the root.
Indirect Volume Rendering of the Tooth

Indirect Volume Rendering of the Tooth

Indirect volume rendering allows to create anatomically accurate 3D models.
Carcinoma of the Lungs

Carcinoma of the Lungs

Combination of manual and automatic segmentation techniques allowed to visualise the tumour in the lungs.
Visualisation of the Brain Tumour

Visualisation of the Brain Tumour

Manual and automatic segmentation techniques were employed to create this visualisation of the brain tumour. Adjusting opacity levels allowed to demonstrate the size and location of the tumour.

Master’s Project: AR and 3D-based mobile application exploring brain anatomy

Neuroanatomy is the section of anatomy that many students find especially challenging. This phenomenon was defined by Ralph F. Jozefovicz as “Neurophobia”. To master neuroanatomy learner must possess strong spatial mapping skills in order to visualise complex neuroanatomical structures and understand how they relate to each other. Textbooks and anatomical atlases are currently the most commonly used resources for teaching neuroanatomy. However, these have some major limitations due to their two-dimensional nature. Cadaveric dissections, which are currently considered a gold standard for studying anatomy, present some serious challenges, from both practical and ethical angles. Considering growing demand for neurologists and specialists in adjacent disciplines, neurophobia amongst medical and life-science students is a serious issue.

Using emerging technologies such as 3D and AR for teaching anatomy (including neuroanatomy) has been proven to be effective in improving learning outcomes of the students. These technologies provided elements of novelty, which helped making the learning experience more exciting and enjoyable. This, in turn, increased students’ motivation and, subsequently, their academic performance.

Building upon previous research, the decision was made to develop an AR and 3D-based mobile application which could be used as a learning aid by anyone willing to master neuroanatomy. The app features AR, 3D and 2D scenes, as well as a short quiz. AR functionality relies on an accompanying booklet, which contains AR-targets.

The application together with the accompanying booklet can be downloaded here: https://drive.google.com/drive/folders/12W9aYfWYVBVDZD-3x-Gju2dyruJTA0gh?usp=sharing

Demo of the AR and 3D-based mobile application exploring brain anatomy

This application was developed to be used by anyone who wishes to introduce themselves to the basics of neuroanatomy. There are three modes: AR, 3D, and 2D, as well as a short quiz. AR scene relies on a booklet containing illustrations of the brain structures, serving as AR targets. 2D mode features labelled illustrations and MRI scans. Finally, the 3D scene features the complex, anatomically accurate model of the brain. The user has the opportunity to zoom in and out using the slider, as well as to explode the model if they wish to see the inner neuroanatomical structures. The user can also rotate the model by swiping the screen along the X axis.

Brain in AR

This is an accompanying booklet containing basic instructions on how to install and use the app. It contains AR targets (the illustrations with "AR" mark), as well as labelled images and MRI scans.

The Life of Yeast

Yuliya was commissioned to create series of educational animations about the life cycle of yeast cells. The software used: Blender, Adobe After Effects

This video concisely describes life cycle of the yeast cells, as well as their inner structure.
