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.John now lectures on topics such as CT, Healthcare Information Technology (HCIT) including PACS and Radiology Information Systems (RIS), Physics, Quality Assurance & supports both under graduate and post graduate research. In 2014, John was a awarded a PhD for his CT research entitled "A study of the efficacy of a predictive correction technique for the metallic beam hardening streak artifact in Computed Tomography of the head".

Research

Research Interests

John has successfully completed a PhD in the field of CT Beam Hardening image artefact suppression. The research investigated a novel predictive algorithm correction technique that identified structures generating beam hardening, and effectively reduced the artifact in an independent single iteration correction step.

The research attracted funding & support from sources including UCD, Siemens Healthcare & Enterprise Ireland.

In addition John supports both post graduate research in the fields of CT and RIS/PACS in addition to under graduate research as part of the BSc Radiography programme.
