Journal Article
Sun, S., Hayes-Gill, B. R., He, D., Zhu, Y., Huynh, N. T., & Morgan, S. P. (2016). Comparison of laser Doppler and laser speckle contrast imaging using a concurrent processing system. Optics and Lasers in Engineering, 83, https://doi.org/10.1016/j.optlaseng.2016.02.021

Full field laser Doppler imaging (LDI) and single exposure laser speckle contrast imaging (LSCI) are directly compared using a novel instrument which can concurrently image blood flow using both LDI and LSCI signal processing. Incorporating a commerc... Read More about Comparison of laser Doppler and laser speckle contrast imaging using a concurrent processing system.

The aimof this work is to demonstrate that the structural and fluidic properties of polymer foamtissue scaffolds, post-fabrication but prior to the introduction of cells, can be engineered via exposure to high power ultrasound. Our analysis is suppor... Read More about Post-processing of polymer foam tissue scaffolds with high power ultrasound: A route to increased pore interconnectivity, pore size and fluid transport.

User needs elicitation via analytic hierarchy process (AHP): a case study on a Computed Tomography (CT) scanner (2013)
Journal Article
Pecchia, L., Martin, J. L., Ragozzino, A., Vanzanella, C., Scognamiglio, A., Mirarchi, L., & Morgan, S. P. (2013). User needs elicitation via analytic hierarchy process (AHP): a case study on a Computed Tomography (CT) scanner. BMC Medical Informatics and Decision Making, 13(2), https://doi.org/10.1186/1472-6947-13-2

Background: The rigorous elicitation of user needs is a crucial step for both medical device design and purchasing. However, user needs elicitation is often based on qualitative methods whose findings can be difficult to integrate into medical decisi...

CMOS sensors for imaging blood flow (2010)
Journal Article
Morgan, S., Hayes-Gill, B., & Crowe, J. (2010). CMOS sensors for imaging blood flow. Optics and Photonics News, 21(1), 32-37. https://doi.org/10.1364/OPN.21.1.000032

Smart CMOS sensors can extract parameters of interest from incoming signals at the sensor and therefore overcome the data bottleneck between sensor and processor. This enables full-field laser Doppler blood flow imaging to be obtained at a frame rate... Read More about CMOS sensors for imaging blood flow.
