Job description

A Vacancy at University College London Hospitals NHS Foundation Trust.

We are looking for a motivated and experienced Medical physicist to join a team of physicists, dosimetrists, engineers and technologists in the provision of Radiotherapy Physics services. You will have specific responsibility for the oversight of Scientific computing within the photon physics team acting as the Medical Physics Expert in that area.

You will have achieved state registration and must be a registered MPE or eligible to apply for MPE status. You will have a proven track record in software development as applied to Radiotherapy, project management experience and a good working knowledge of Quality Management Systems.

You will have a solid background in all aspects of Radiotherapy Physics; External beam treatment planning techniques; Radiotherapy machine quality assurance. Knowledge of Brachytherapy would be an advantage but not essential.

Experience in leading and motivating a team is essential as well as a track record in staff training and teaching.

The main purpose of this post is to provide senior oversight of the work of the Photon Physics team within the Radiotherapy Physics group. The main area of responsibility will be in the management of software development and oversight of integration of software into the clinic.

Close liaison with the radiotherapy radiographers, clinical oncologists and the Clinical Scientific Computing group is expected for the ongoing delivery of the Radiotherapy service.

Main duties

• The main role of this post is to provide scientific and managerial support within a particular aspect of the work of the Radiotherapy Physics group.
• To act as a Medical Physics Expert, as defined in IR(ME)R 2017, to ensure that Trust complies with all safety legislation in the remit of the radiotherapy physics department.
• The postholder will work over a range of areas in Radiotherapy Physics and will undergo continual professional development in Radiotherapy and associated techniques.
• The post-holder will lead and take responsibility for major developments in the radiotherapy physics service, including equipment specification, acceptance testing and commissioning, managing teams to complete and implement developments to agreed timescales.
• The postholder will be responsible for and supervise on a day-to-day basis the development and management of in-house software applications.
• The post-holder will deputise for the Leads in the major sub-sections of Treatment Planning and Dosimetry and QA, including day-to-day management of teams to ensure services are delivered as intended.
• The post requires handling of highly complex dosimetry equipment to perform and supervise routine calibration and monitoring of highly complex radiation producing equipment.
• The post requires the provision of highly specialised advice and guidance, where necessary, to the Radiotherapy Department in matters relating to treatment plans, dosimetry, and radioactive isotope treatments.
• The post requires the presentation of clinical data to medical staff and the upholding of legal requirements.

Radiotherapy Physics Services consists of a team of over 80 staff consisting of clinical scientists, dosimetrists and engineers.

The Radiotherapy Physics Section is part of a multi-disciplinary team in the Department of Clinical Oncology, which sees about 2000 new patients per year. The Radiotherapy Department is equipped with four Varian TrueBEAM linear accelerators and one Halcyon machine. The department equipment also includes one orthovoltage unit and an Elekta High Dose Rate Brachytherapy unit. Planning equipment includes a Siemens CT simulator with full 4D imaging capabilities for Respiratory Gated studies. The department offers a variety of specialised treatment services and is continually developing advanced treatment techniques.

UCLH provides one of two national Proton Beam Therapy (PBT) centres for the UK. The proton department is equipped with four Varian ProBEAM gantries with dedicated CT and MR planning. ARIA and Eclipse is in use across both radiotherapy and proton therapy. The proton service is sited within the Trust’s campus in the heart of the capital where it enjoys a close collaboration with UCL on ground breaking research projects. The site has direct access to the Trust’s existing radiotherapy department and will be a closely located to the University College Hospital Macmillan Cancer Centre.
