UK manufacturer e2v technologies announced it has supplied 40 of its radio frequency (RF) systems to TomoTherapy Inc., of Madison, Wisc., for use in its Hi-Art radiotherapy system. The modulator is a high-voltage, direct switching unit designed for linear accelerator (LINAC) machines, which provide x-rays used in the imaging and treatment of tumors. The RF system incorporates the compact modulator, a three-phase power supply, a control system, a magnetron with electromagnet and a microwave launching system. ev2 will exhibited it at ASTRO 2004, the annual exhibition of the American Society for Therapeutic Radiology and Oncology, Oct. 3-7 in Atlanta. . . . Toshiba Corp. on Tuesday unveiled a flat-panel TV that uses surface-conduction electron-emitter display (SED) technology, which it developed with Canon. The new displays use beam-emitting technology similar to the old-style cathode-ray tube televisions and deliver similar clear imagery but onto a flat panel. Toshiba said it plans to market SED TVs by April 2006 and that they will be compatible with high-definition DVDs. It also plans to sell liquid-crystal and plasma displays with SED technology meant for 40-inch and larger models, it was reported. The SED was created through the merging of Canon's proprietary electron-emission and microfabrication technologies with Toshiba's cathode-ray-tube technology and mass-production technologies for liquid-crystal displays and semiconductors.
