Undertake routine and complex treatment planning for external beam radiotherapy. Carry out associated dosimetry calculations, in accordance with clinical prescription and agreed procedures. Analyse requirements and make complex judgements regarding treatment parameters and patient dose effects to produce the required dose distribution over the treatment volume, using computerised planning systems as appropriate. Advise clinical staff on the effects of various treatment plan options on patient dose distributions. Discuss and agree approaches with clinical staff to create optimum treatment plans and advise on aspects of the treatment and patient set-up, as required. Assist with the provision of routine physics support to brachytherapy treatments. Carry out dose calculations and prepare patient dose distributions. Assist with providing routine support for physics dosimetry and quality control in radiotherapy, according to established protocols. Undertake dosimetry measurements to a high degree of accuracy with suitable equipment. Perform quality control and other measurements and procedures on highly complex, expensive (>£1 million) patient-critical equipment. Perform and advise on dosimetry measurements on patients. Provide complex advice to clinical staff and support developments in in-vivo dosimetry and mega voltage imaging. Assist in the maintenance, application and development of treatment planning computer systems. Provide scientific and technical advice to radiotherapy consultants and other staff regarding the treatment of patients. Maintain HCPC registration. Participate in the on-call/bleep Duty Physicist rota. Please see job description/person specification for full details on the role.
