During my undergraduate degree I was introduced to Biomedical Ultrasound on a project where I was designing large scale Transcranial Doppler Ultrasound flow phantoms for use at public engagement events. At this time, I also took a strong interest in secondary education, and volunteered as a maths tutor in local schools for two years. I decided to train to teach with the charity ‘Teach First’ and worked in a school on the South Coast for two years, where I qualified as a Science Teacher.

I joined the Biomedical Ultrasound Group in September 2018, as part of the Centre for Doctoral Training in Medical Imaging.

Current Work

Existing Ultrasound Computed Tomography (UCT) systems are custom-built at high cost and with a long lead time, which can be prohibitive for some research groups. I am working on ‘FlexUCT’, which will be an open-source, low-cost UCT ring array, that can be manufactured in-house with a short lead time, using commonly available rapid prototyping technology and workshop equipment, and will be easily adaptable so that research groups can customise the system to suit their requirements. The hardware distribution will provide the complete specification needed to build a UCT ring array, including 3D printing design files, and printed circuit board (PCB) layouts.

I am currently developing a novel method for depositing matching layers with a known and controllable thickness, which improves on previous work in the literature. This is significant, because the method is flexible and independent of both the PZT element geometry and the required matching layer thickness. I am also working on a novel method to align PZT elements during manufacture which has resulted in excellent element alignment both in the scan and orientation planes for the prototypes, which has been demonstrated experimentally using microCT scans and an analysis of the beam orientation in the pressure field.
