Abstract

Accurate radiotherapy delivery is required for curing cancer. Historical radiotherapy accuracy studies at Leeds (1983-1991) are discussed in context of when radiographers were not involved in practice design. The seminal research was unique in being led by a radiographer practitioner, and in prospectively studying the accuracy of different techniques within one department. The viability of alignment of treatment beams with marks painted on a patient's skin varied daily, and, using film I showed that the alignment of treatment on anatomy varied. I then led 6 sequential studies with collaborating oncologists. Unique outcomes were in identifying the origins of treatment inaccuracies, implementing and evidencing changes in multi-disciplinary practice, thus improving accuracy and reproducibility generally and achieving accuracy for the pelvis to within current norms. Innovations included: discontinuation of painted skin marks and developing whole-body patient positioning using lasers, tattoos, and standardised supports; unification of set-up conditions through planning and treatment; planning normal tissue margins round target tissue to allow for inaccuracies (1985); improved manual shielding methods, changed equipment usage, its quality assurance and design; influenced the development of portal imaging and image analysis. Consequences and current implications. The research, still cited internationally, contributed to clinical management of lymphoma, and critically underpins contemporary practice. It led to my becoming the first radiographer invited into multi-disciplinary collaborative work, to advise in the first multi-centre clinical trials to consider treatment delivery accuracy, contribute to books written from within other disciplines and inform guidelines for good practice so helping to improve practices, with recent publications. I thus led my profession into research activity. Later work included development of a national staffing formula for radiotherapy Centres, and contributing to the evidence-base for improved National radiotherapy resourcing. I recently researched and developed a textbook (second edition) on quality in treatment delivery.
