roles based modular isozentrischer carriers and methods for its use.

摘要

An earthquake resistant, roller-supported, modular, isocentric gantry for supporting and rotating a radiation beam transport and delivery system on an axis of rotation around a stationary patient so as to precisely deliver a treatment beam to a predetermined target isocenter within the patient from several different angles during patient treatment. The gantry is formed of three primary building blocks: a conical inner support structure, an outer segmented, modular truss structure and a ladder truss which may be assembled in the field to form an isocentric gantry.
