Abstract
Electron beam therapy of lesions such as cutaneous metastatic carcinoma and reticulum cell sarcoma is performed via multiple portals for a wide irradiation field. However, the dose distribution in border areas is generally uneven, resulting in hot and cold dose areas depending on the intervals of the portals. We performed electron irradiation by the pendulum technique, especially on curved areas, and evaluated the technique in various respects. Pendulum electron beam irradiation is indicated when the length of the cone must be reduced in order to deliver the target volume near the skin surface as well as to avoid the occurrence of hot spots deep in the body. We prepared a 15cm rotating cone by cutting a 30cm fixed irradiation cone. The modification posed no disadvantages in terms of extent and flatness of the beam, or stability during rotation. After determining the relationship between the rotation speed and the dose, the technique was successfully applied to a patient with adult T-cell lymphoma, at a total of 3000cGy.
