Abstract

Objectives: To survey kilovoltage (kV) radiotherapy in the UK, updating a 2016 study, focussing on radiotherapy physics, including equipment quality control (QC) and radiation dosimetry, with information on installed equipment and clinical activity.

Methods: All UK radiotherapy physics departments (n = 68) were invited to complete a comprehensive survey. An analysis of the installed equipment base, patient numbers, clinical activity, QC testing and radiation dosimetry processes were undertaken.

Results: 91% of centres (n = 62) responded to the survey. kV radiotherapy was available in 70% of UK radiotherapy departments, with a wide variation in workload; 7 to 436 patients/centre annually. There has been an increase in the centres using treatment calculation software rather than manual methods, up from 36% in 2016 to 50% in the current study. Only 50% of centres use a calculation check method different to the primary method. There was also an increase in use of the addendum to the UK dosimetry code of practice, enabling medium energy calibration in-air rather than at depth in phantom, citing "clinical relevance". Appropriate levels of quality control testing were being conducted at UK centres, with IPEM Report 81 cited as a primary source of guidance. Good consensus for the frequency and tolerance values used for QC was seen across UK centres.

Conclusions: A comprehensive review of consensus practice for quality control and dosimetry in kV radiotherapy across the UK is presented, with supporting information on equipment installation and clinical use.

Advances in knowledge: Updated data is presented on kV radiotherapy treatment in the UK, with focus on physics aspects of QC and dosimetry.

期刊介绍: BJR is the international research journal of the British Institute of Radiology and is the oldest scientific journal in the field of radiology and related sciences. Dating back to 1896, BJR’s history is radiology’s history, and the journal has featured some landmark papers such as the first description of Computed Tomography "Computerized transverse axial tomography" by Godfrey Hounsfield in 1973. A valuable historical resource, the complete BJR archive has been digitized from 1896. Quick Facts: - 2015 Impact Factor – 1.840 - Receipt to first decision – average of 6 weeks - Acceptance to online publication – average of 3 weeks - ISSN: 0007-1285 - eISSN: 1748-880X Open Access option
