Biography

John Stowe joined the UCD School of Medicine and Medical Science in January 2007. This followed from 20 years of experience in the Diagnostic Imaging industry. The years from 1986 to 1999 were spent in Siemens Ireland as a service engineer specialising in Computerised Tomography (CT), Nuclear Medicine & Picture Archiving and Communications Systems (PACS). John was also an Advanced Clinical Applications Specialist for Siemens workstations and software. By 1999 John had become Service Manager for these imaging specialities. During this time John successfully undertook a Higher Diploma in Physical Sciences in Medicine.

In late 1999, John took up a position with GE Healthcare (Ireland) as Medical Systems Product Specialist. Shortly afterwards, he became the Diagnostic Imaging Service Manager for Ireland. In 2003, John took up the role of PACS Business Manager for Ireland. In this role he grew GE's market share from its fledgling position to the dominant supplier of this product in the Irish marketplace by January 2007.

For 17 years prior to joining UCD in a full time capacity, John had also been a guest lecturer at under & post graduate level for UCD in the areas of CT Technology, Image Quality, Healthcare IT and Medical Standards.

Research

Research Interests

I am currently engaged in PhD research in the field of CT Beam Hardening image artefact. The research will investigate a novel predictive algorithm correction technique that may identify structures generating beam hardening, and effectively reduce or even eliminate the artifact in an independent single iteration correction step.

The research is now in it's third year and has attracted funding & support from sources including UCD, GE Healthcare & Enterprise Ireland. The prototype program containing the automated correction algorithm is currently undergoing validation through the use of the UCD onsite CT reconstruction engine funded by Enterprise Ireland.

An additional research project is commencing into data protection and anonimisation is now commencing.
