The department provides a comprehensive physics service to support the delivery of radiotherapy treatment atNorth Middlesex Hospital. This includes all treatment planning, machine quality assurance and the provision of molecular radiotherapy. The department consists of 10 clinical scientists, including this post, 6 dosimetrists and 6 engineering and technical staff.

The Radiotherapy department has a mix of Varian TrueBeam and Halcyon Linacs and an XStrahl superficial unit. Varian Eclipse is used for all treatment planning activities, and we have ongoing projects to implement and expand knowledge based planning, AI auto-contouring, scripting and automation, and lots more besides.

Main duties of the job

The senior physicist's role is to ensure the safe delivery of the Radiotherapy Physics Service at North Middlesex University Hospital, assisting the Head of the service as well as other designated Medical Physics Experts (MPE) in their various areas of responsibility.

About us

North Mid is part of North Central London integrated care system - consisting of the NHS and Local authority organisations in Camden, Islington, Barnet, Enfield and Haringey. As with other ICS's, we are working increasingly closely with partners and indeed many of our financial and performance objectives are measured at this system level. Whilst all organisations remain as standalone, statutory bodies we have an ICS infrastructure for making shared decisions and agreeing shared approaches.

We are proud of our staff and want to ensure their training allows them to provide excellent clinical care. We are also a training unit for medical students from UCL and St George's University Grenada, and for nursing and midwifery students from Middlesex and City Universities.
