I am a PhD student, developing medical ultrasound devices for breast imaging and brain therapy.
I studied Acoustic Engineering for my undergraduate degree, and then trained and worked as a secondary science teacher for two years before joining the Biomedical Ultrasound Group in September 2018, as part of the Centre for Doctoral Training in Medical Imaging.
My main interests are medical device engineering to EN 60601 / ISO 14971, transducer characterisation. and image reconstruction.
Ultrasound Tomography (UST) is a promising new imaging modality that generates sound speed and absorption maps of the breast, and is being developed as a non-ionising, pain free alternative to mammograms. I am developing an open-source UST system that end-users can manufacture in-house. The system is modular so that different system configurations can be used to meet specific research needs, without the high costs and long lead times associated with custom commercial transducers.
The production workflow has been optimised to be as simple as possible for end-users, whilst still producing ultrasound transducers with acoustic performances that consistently match their specification.
The design uses off the shelf parts, with no special equipment required other than a 3D printer. The cost for a 256-element system will be £1.6k.
The freely available hardware distribution will be released in summer 2021, and will include parametric CAD models, Gerber and STL files for PCB production and 3D-printed parts, a bill of materials, and extensive documentation of manufacture and calibration procedures.
I’m part of a multidisciplinary team developing a device that will be used to modulate the neural activity in the deep brain of Parkinson’s patients, non-invasively. A multielement array is used to focus ultrasound energy towards a very small target region, which can be tightly controlled using electronic steering.
I work on the electrical subsystem for the device, which must drive the ultrasound elements according to a treatment plan, requiring high signal integrity. The main challenges here are cross talk, MRI compatibility/EMC, and electrical safety to EN 60601.
