Method for automatically indexing cast field shaping blocks to a radiation therapy treatment tray and a cooling tray for cast blocks

摘要

A method is described for indexing a polyfoam block in which a metal field shaping block is cast to both the cutting tray of a hot wire cutting system and the treatment tray of a radiation therapy treatment machine. The cast metal field shaping block is automatically correctly oriented for treatment. A cooling tray for cooling the casting is also described.
