Development and Translation of intra-Tracheal Multiplexed Sensing Endotracheal Tubes (iTraXS) (2020)
Presentation / Conference Contribution
Morgan, S. P., Correia, R., Korposh, S., Al-Badri, M., Hayes-Gill, B. R., Norris, A. M., Sinha, R., Hardman, J. G., Gardner, D. S., & Talbot, S. (2020, April). Development and Translation of intra-Tracheal Multiplexed Sensing Endotracheal Tubes (iTraXS). Presented at Biophotonics Congress: Biomedical Optics 2020 (Translational, Microscopy, OCT, OTS, BRAIN), virtual

An endotracheal tube with integrated optical fibre sensors (fibre Bragg grating and photoplethysmography) is described. The system aims to ensure the appropriate cuff inflation pressure to achieve a gas seal but reduce pressure injury.

Ultrasound modulation of bioluminescence generated inside a turbid medium (2017)
Presentation / Conference Contribution
Ahmad, J., Jayet, B., Hill, P. J., Mather, M. L., Dehghani, H., & Morgan, S. P. (2017, January). Ultrasound modulation of bioluminescence generated inside a turbid medium. Presented at Photons Plus Ultrasound: Imaging and Sensing 2017, San Francisco, California, United States

In vivo bioluminescence imaging (BLI) has poor spatial resolution owing to strong light scattering by tissue, which also affects quantitative accuracy. This paper proposes a hybrid acousto-optic imaging platform that images bioluminescence modulated... Read More about Ultrasound modulation of bioluminescence generated inside a turbid medium.
