“…Nakamura et al [11] and O'Doherty et al [12] both observed inconsistent bladder volume during the course of radiotherapy when using a full bladder protocol, whilst irregular prostate motion has been attributed to both bladder filling and patient movement [13]. Previous studies have also investigated the impact of rectal diameter on prostate motion [14][15][16]. However, in these studies either real-time imaging or bladder volumes was missing in the study design.…”

“…This was further investigated by Oates et al, concluding that a mean rectal diameter measured on daily CBCT of less than or equal to 3.5 cm would result in a prostate displacement of less than or equal to 5.5 mm. 16 Rotation was evident in our results, particularly when considering the magnitude and frequency of pitch (Table 5 and Fig. 3).…”

“…Bowel protocols minimise these rectal differences, however, even if the patient has an acceptable rectal diameter on planning scan, a small difference in rectal diameter at treatment can produce a large difference in prostate displacement and rotation. This was further investigated by Oates et al, concluding that a mean rectal diameter measured on daily CBCT of less than or equal to 3.5 cm would result in a prostate displacement of less than or equal to 5.5 mm …”

“…While the variability in location of external skin markers relative to internal anatomy in obese patients caused a signi cant difference in terms of interfractional prostate shift (15), there was no relationship between body mass index (BMI) and intrafractional prostate motion (16). It was reported that the shorter the maximum rectal diameter is, the less the intrafractional prostate motion is (17).…”
