Abstract

Radical radiotherapy of pelvic malignancies (e.g., vulva, anus) includes therapeutic dosage to the inguinal nodes. To minimize the dosage to the femoral head, the transmission block technique has been developed to fully irradiate the central pelvis midplane and inguinal nodes. Originally, this technique compensated for dose inhomogeniety in the transverse plane only. In some patients, however, we have observed a significant dose variation along the sagittal plane. The authors have developed a lead compensation technique to homogenize the sagittal dose variations due to the longitudinal sloping in the patient, along with further refinements in this technique. Dosimetric and technical details are also discussed.
