Figure 4

Simulated diagram of cumulative dose distribution in Patient 1. The dose distribution was simulated in a case if the re-irradiation of 50 Gy were to be administered by 3D conformal X-ray radiotherapy using an orthogonal 4-field technique. The cumulative radiation dose to the bowels is greater than 70 Gy because of the overlap of the initial and re-treatment radiation fields. The red lines indicate the anterior-posterior field of the initial radiotherapy.
