Abstract

<abstract abstract-type="normal"> <title>Abstract</title> <sec id="abs1" sec-type="general"> <title>Purpose</title> <p>The aim of this study was to assess the feasibility of radiographer led verification of cone-beam computed tomography (CBCT) images for patients with solitary lung tumours treated with stereotactic body radiotherapy treatment (SBRT).</p> </sec> <sec id="abs2" sec-type="general"> <title>Material and methods</title> <p>CBCT setup images of 20 patients from the first fraction of each patient were retrospectively registered by therapeutic radiographers. The displacements recorded were compared with the clinical oncologist's original online match. The time taken by radiographers to verify the CBCT images was also recorded.</p> </sec> <sec id="abs3" sec-type="results"> <title>Results</title> <p>Overall agreement for all radiographers when compared with the clinical oncologist match was 91%. Interobserver variations between radiographers were <italic>X</italic> plane 0·87 (0·76–0·94); <italic>Y</italic> plane 0·74 (0·51–0·88); and <italic>Z</italic> plane 0·88 (0·78–0·95) intraclass correlation coefficient and 95% confidence interval. The average time taken for verification was 128 seconds.</p> </sec> <sec id="abs4" sec-type="conclusion"> <title>Conclusion</title> <p>Therapeutic radiographers are able to verify CBCT images for thorax SBRT with results comparable to the 'gold standard' clinical oncologists' match, however additional training will be provided for online verification. The time taken was within acceptable limits.</p> </sec> </abstract>
