Irregular-shaped fields in electron radiotherapy

Department of Radiotherapy Physics, Walsgrave Hospital, Clifford Bridge Road, Walsgrave, Coventry CV2 2DX, UK

This excerpt was created in the absence of an abstract.

We read with interest the technical note describing an irregular field technique for electrons, (Plane & Usher, 1990). On our SL 25, at Coventry, we have used a similar technique for over a year with satisfactory results.

On our SL 25, no modification to the applicator is required which makes this technique readily applicable. Perhaps more importantly the shielding alloy we use is MCP 69, and the accessories are cast in an aluminium moulding tray of a size specific to the applicator used. No pre-heating or forced cooling is required making the casting process simpler and possible without special equipment in addition to the moulding trays.
