About Our Team
Within the Photonics Instrumentation Group (PhI), and specifically the TannerLab sub group, we exploit novel photonic techniques such as time resolved single photon technologies, spectral imaging, and optical fibre sensors to tackle clinical/biomedical challenges and other real world applications.
Our work is primarily experimental, developing measurement systems and principles, with theory and analysis to support this. We strongly collaborate with clinical practitioners in order to move those systems towards application.
Some of our work is research level lab development, however some projects are strongly focused on practical translation – taking novel or well established principles from the lab to useful implementation. We have pathways to take new medical devices and techniques through to pre-clinical testing and early in-human testing, with full support for regulatory approval, to perform patient trials in the hospital wards in collaboration with the University of Edinburgh and NHS Lothian.
This position is a funded impact project focused on working closely with an external company, Tiny Air, a growing company who develop surgical instrument cleaning systems. This will be a great opportunity for experience working with industry colleagues, expanding Tiny Air's capabilities through incorporating imaging technologies with their current systems, and being involved in the pathway to real implementation in surgical decontamination facilities.
This work will also be supported by Business Development teams at Heriot-Watt University.
The position is available for immediate start, however timing can be discussed.
For further information or to discuss the role, contact the Principal Investigator, Dr Michael Tanner, M.Tanner@hw.ac.uk.
Detailed Description
This project has a broad multidisciplinary scope – it is not expected that a candidate will have experience in every aspect mentioned, and our team can support you. We will be very happy to hear what you can bring to the project, and we will work together to achieve the goals.
In collaboration with Tiny Air Limited we are seeking to develop a cobot inspection system to assist surgical instrument decontamination. Tiny Air are transforming surgical decontamination with their pre-cleaning technology. A new cobot inspection system would augment this technology and create stand-alone units within washroom and cleanrooms.
We will develop widefield fluorescent imaging techniques to segment contamination from instruments, with automated multi-spectral overlay, to delineate tissue types (bone/flesh/adhesives/other). Practical translational demonstration, TRL advancement, and system integration of the photonic techniques is the project deliverable, for commercial and health economic impact.
Further Detail
We have demonstrated proof of concept on the lab bench of a UV 'elucidation' method. This identified previously missed bone fragments that had passed manual inspection at a decontamination facility. This project aims to expand the capabilities of this fluorescence imaging technique, increase the automation and analysis, and work with Tiny Air for practical integration with their automated systems.
In this collaborative project we will lead technical development and integration of dual photonic imaging systems (one early integration, one advanced). The current prototype single fluorescence channel system will be translated with Tiny Air automation. Alongside this, an advanced multi-colour system will be developed for later substitution once demonstrated at sufficient TRL. Characterisation of tissue/bone/adhesive spectral properties will be performed with existing facilities, guiding interpretation of spectral images. As such, tissue, blood, and bone will be separately labelled for the user. Systems will be tested with instruments of varying degrees of contamination with the identified partners.
