Abstract
Uniform electron irradiation of tissue over a large solid angle is accomplished by directing an electron beam of selectively variable energy and intensity through a hollow needle to emerge in the interior of a tissue equivalent scattering body adapted for insertion into a surgical opening. Multiple scattering of electrons in the interior of the scattering body produces a flux emerging from the surface of the body, which flux exhibits a desired distribution of intensity and kinetic energy (depth of penetration) over a large solid angle interval for radiation treatment of surrounding tissue.
