SYNCHRONOUS SHIELDING AND FIELD SHAPING FOR MEGAVOLT IRRADIATION OF ADVANCED CERVICAL CARCINOMA

DAVID N. ILFELD B.S., KENNETH A. WRIGHT M.S., and FERDINAND A. SALZMAN M.D.

A method of synchronous shielding and field shaping for megavolt x-ray rotational therapy of carcinoma of the cervix is presented.

Metal absorbers protect the bladder, rectum, and small intestine during 360° rotation while other blocks contour the shape of the x-ray beam to the known and estimated tumor volume.

Tests with a masonite phantom indicate a tumor dose homogeneity of ± 10 per cent. The head of the femur received 30 to 50 per cent, the bladder 60 to 85 per cent, the rectum 60 to 70 per cent, and the small intestine 30 to 70 per cent of the tumor dose.

This technique optimizes the tumor dose relative to the adjacent normal tissue dose, thereby permitting higher radiation levels to be delivered to the entire tumor by external irradiation alone.
