A Multicentre Timing Study of Intensity-modulated Radiotherapy Planning and Delivery

Outlining times (minutes) by intensity-modulated radiotherapy technique/department.

Outlining times (minutes) by oncologist.

Process times (days). See text for an explanation of processes.

Task times (hours) for planning and checking.

Task times (hours) for quality assurance measurements and analysis.

Times for each subtask of the process for first fractions. Imaging times at Norfolk and Norwich (N&N) are included in the ‘beam’ times.

Times for each subtask of the process for subsequent fractions. Imaging times for Cambridge step-and-shoot (Cam S&S) are averaged over the course of treatment, including fractions without imaging. Imaging times at Norfolk and Norwich (N&N) are included in the ‘beam’ times.
