DOI: 10.1109/tuffc.2022.3169082
Abstract: The successful integration of computer vision, robotic actuation, and photoacoustic imaging to find and follow targets of interest during surgical and interventional procedures requires accurate photoacoustic target detectability. This detectability has traditionally been assessed with… read more here.

DOI: 10.1111/1754-9485.12561
Abstract: Computed tomography perfusion (CTP) is increasingly employed in the diagnosis and management of ischaemic stroke but radiation dose can be significant and optimising contrast‐to‐noise ratio (CNR) is challenging. This study aimed to quantify and optimise… read more here.
