    摘要: This invention helps achieve accurate focussing of therapeutic radiation at an internal structure (e.g. cancerous organ), which is often substantially movable within a living body. For this purpose, suitable sensors are laproscopically or surgically implanted at the location of the organ. These sensors may include semiconductor materials, scintillation materials, piezo-acoustic materials, x-ray emitters, or other materials which emit a signal when they are scanned by a beam of harmless investigative radiation, such as low intensity therapeutic radiation. The emitted signal is then monitored via implanted wires or light fibers or via external detectors during scanning to determine the targetted location at which a signal maximum occurs, whereupon the desired intensity of therapeutic radiation is focussed on this targetted location.

    摘要: The invention allows more accurate localization of radiation volumes during radiation treatment of tumors. The equipment includes radiation detector elements placed behind the patient during radiation, for treatment of a tumor condition. Such a detector may be constructed of semiconductor or a scintillating material. The radiation treatment plan for the patient includes an additional calculation of the treatment beam energy required for to enable the treatment beam to transit the patient. The energy required for patient transit is then measured, using a treatment beam with a beam current below that which will induce significant tissue damage. The experimental transit flux is then compared to the calculated transit flux, and the difference is used to correct the beam transport parameters in the original radiation treatment plan. Hence lower radiation doses and smaller radiation volumes can be achieved, reducing deleterious radiation side effects.

    摘要: The invention provides a system for therapeutic treatment of an organ, tumor, or other internal structure of a living body with therapeutic radiation after implantation, at the organ, of a magnetic element to identify the location of the organ, the element being capable of emitting a magnetic signal in response to an applied magnetic field. The system comprises a magnetic field generator for irradiating the magnetic element with an applied magnetic field, a movable magnetic field sensor for detecting the magnetic signal from a plurality of selected mutually displaced positions to produce a corresponding plurality of element-locating signals, a computing apparatus for converting the signals to a location image of the internal structure, and a controlled source of therapeutic radiation for focussing a selected degree and duration of therapeutic radiation at a target determined from the location image of the magnetic element. Preferably, the magnetic element is a length of wire of an amorphous magnetic material which produces a magnetic signal that exhibits non-linear Bark+hausen jumps in response to an applied ac magnetic field.

    摘要: A method of formation of a microelectromechanical system (MEMS) resonator or filter which is compatible with integration with any analog, digital, or mixed-signal integrated circuit (IC) process, after or concurrently with the formation of the metal interconnect layers in those processes, by virtue of its materials of composition, processing steps, and temperature of fabrication is presented. The MEMS resonator or filter incorporates a lower metal level, which forms the electrodes of the MEMS resonator or filter, that may be shared with any or none of the existing metal interconnect levels on the IC. It further incorporates a resonating member that is comprised of at least one metal layer for electrical connection and electrostatic actuation, and at least one dielectric layer for structural purposes. The gap between the electrodes and the resonating member is created by the deposition and subsequent removal of a sacrificial layer comprised of a carbon-based material. The method of removal of the sacrificial material is by an oxygen plasma or an anneal in an oxygen containing ambient. A method of vacuum encapsulation of the MEMS resonator or filter is provided through means of a cavity containing the MEMS device, filled with additional sacrificial material, and sealed. Access vias are created through the membrane sealing the cavity; the sacrificial material is removed as stated previously, and the vias are re-sealed in a vacuum coating process.
