Lethal and sublethal damage repair inhibiting image guided simultaneous all field divergent and pencil beam photon and electron radiation therapy and radiosurgery

A medical accelerator system is provided for simultaneous radiation therapy to all treatment fields. It provides the single dose effect of radiation on cell survival. It eliminates the inter-field interrupted, subfractionated fractionated radiation therapy. Single or four beams S-band, C-band or X-band accelerators are connected to treatment heads through connecting beam lines. It is placed in a radiation shielding vault which minimizes the leakage and scattered radiation and the size and weight of the treatment head. In one version, treatment heads are arranged circularly and connected with the beam line. In another version, a pair of treatment heads is mounted to each ends of narrow gantries and multiple such treatment heads mounted gantries are assembled together. Electron beam is steered to all the treatment heads simultaneously to treat all the fields simultaneously. Radiating beam's intensity in a treatment field is modulated with combined divergent and pencil beam, selective beam's energy, dose rate and weight and not with MLC and similar devices. Since all the treatment fields are treated simultaneously the dose rate at the tumor site is the sum of each of the converging beam's dose rate at depth. It represents the biological dose rate. The dose rate at d-max for a given field is the individual machine dose rate. Its treatment options includes divergent or pencil beam modes. It enables to treat a tumor with lesser radiation toxicities to normal tissue and higher tumor cure and control.

Threaded actuator for positioning structure subjected to intense loads

A threaded actuator is disclosed for positioning a core in a molding apparatus. The threaded actuator includes a hydraulic cylinder unit having a piston rod connected to the core for positioning thereof. The core is subjected to intense force during the molding process and this force is transmitted onto the piston rod and hydraulic cylinder unit and its support. The hydraulic cylinder has a threaded nose which is secured within a threaded opening in a support. A rotatable threaded connecting member is threaded between the threaded nose and the threaded opening of the support structure. The outer and inner threaded connections of the rotatable threaded connecting member are of different thread configurations to form a differential thread assembly. The configurations may differ either in pitch and/or in the handedness of the threads. The differential threaded assembly provides for relative positioning of the hydraulic cylinder unit and core relative to the mold. A preload system includes a wall on the cylinder and a wall on the rod for preloading of the locked rod and the supporting components. The hydraulic cylinder and the piston rod are formed with stop wall members which provide for controlled extension of the piston rod for preloading of the piston rod and the supporting structure. A locking unit provides for locking of the rod in an extended position.
