Summary of Work

The 3D digital head and neck is constructed from sources including anatomical data acquired from 3D laser scans and radiography of human cadavers. This data is then integrated within a bespoke visualization platform to create a high quality real-time interactive 3D digital model. Furthermore, haptic force feedback interaction is added for dental training purposes.

Take-home Messages

The 3D medically verified head and neck model is the first highly detailed 3D stereoscopic model of human body. This model aims to improve knowledge and skills among medical professionals through real-time interaction of realistic data sets. Thereby it seeks to increase the efficiency and productivity in healthcare and to enable remote learning. The simulation of dental injection allows students to simultaneously learn the anesthetic technique and its relevant anatomy. Further integration with haptic force feedback enables students to touch and feel the oral tissues while practicing anesthetic techniques in a safe and repeatable environment.

Background

The sound understanding of human anatomy is vital for students pursuing medical, dental and paramedical careers. However, restricted availability of cadaveric dissection sessions and the lack of accurate anatomic models of the human body have posed problems in medical education over the last decade. The 3D Definitive Head and Neck project, a pioneering collaborative project between Digital Design Studio, University of Glasgow and NHS Education for Scotland has addressed this problem by providing highly detailed interactive 3D anatomic visualizations.

Summary of Results

The 3D Definitive Human allows students and teachers to learn the anatomy by interacting with the fully labeled model in a real-time 3D environment and by performing virtual dissections layer by layer. 

A user can learn about individual structures in great detail by interacting with them in 360 degrees. By turning superficial structures transparent, the deeper layers can be explored for a better understanding. The spatial distribution of various structures can be studied with the help of the bespoke explore tool. Integrating this with MRI/CT Scan data helps students to correlate with the radiographic anatomy.

Conclusion

High-resolution data capture and accurate modeling supported by specialist clinical inputs makes the 3D head and neck a highly reliable resource to support anatomic learning, by allowing intuitive and self-paced exploration with a level of details never possible before. Real-time interactivity and haptic force feedback provide increased scope for training and research.

Further development of this project includes a complete model of male and female human bodies. With the head and neck model already medically verified by experts, the next big challenge is to complete the validation of the haptic simulation of dental injection, which is currently under progress.
