Recent updates from PURL including conference attendances, papers and awards.


Mengjie Shi delivered two fantastic presentations at the @SPIE Photonics West! She demonstrated how deep learning can be used to improve blood oxygen saturation measurements using LED photoacoustic imaging and reduce skin tone bias.


Mengjie Shi focusing presented her work on learning-based sound-speed correction for dual-modal photoacoustic/ultrasound imaging at the 2023 IEEE International Ultrasonics Symposium (IUS). Watch the presentation here. A proceedings paper is due for publication.


Dr Tianrui Zhao has been awarded the prestigious Royal Academy of Engineering Research Fellowship for his research into new methods of photoacoustic imaging to improve the diagnosis of breast cancer. The RAEng Research Fellowships programme supports outstanding early-career researchers to become future research leaders in engineering.


Dr Tianrui Zhao presented his work "All-optical multimode fibre photoacoustic endomicroscopy with scalable spatial resolution and field-of-view" at the SPIE Opto-Acoustic Methods and Applications in Biophotonics VI event, part of European Conferences on Biomedical Optics. An accompanying proceedings paper has also been published.


Dr Tianrui Zhao and Dr Wenfeng Xia have submitted a patent application for their work on spatial light modulation for endoscopy (Wenfeng XI, Tianrui ZH, Vercauteren T, Ourselin S. Apparatus and method for spatial light modulation. United States patent application US 17/792,914. 2023 Jul 27.)


Christian and Mengjie attended SPIE Photonics West in San Francisco. Christian presented an invited paper on his needle tracking work, and a second paper introducing the new 3D tracking project. Mengjie presented a paper on improving the frame rate of photoacoustic microscopy with deep learning, and two posters: one on denoising LED photoacoustic imaging and another on photoacoustic visualisation of needles. 


A new collaborative project "Next-generation 3D ultrasonic needle tracking" with BICI has officially started. The project will utilise recent developments in tracking technology from PURL to deliver a new 3D tracking platform for minimally invasive surgical and interventional procedures, working towards commercialisation. Christian Baker is the technical lead.


Tianrui has had a paper describing his work in photoacoustic microscopy published in Applied Sciences.
