Dose volume histogram (DVH) reflecting dosimetric advantages with temporary organ displacement (TOD), bowel. The planning target volume (PTV) D95 increased from 1351 cGy to 2372 cGy while the D05 decreased from 2711 cGy to 2516 cGy. The GTV Dmin increased from 1025 cGy to 2262 cGy. The pre-TOD and post-TOD bowel Dmax were 1600 cGy and 743 cGy, respectively. Dose delivered to bowel by cone-beam computed tomography was 794 cGy. *DVH corresponds to patient 3 in Table 1.
