摘要： A vaginal brachytherapy applicator has an insertable tip section, preferably rigid or at least firm enough to retain its shape when inserted, and a tubular handle section extending proximally from the tip section. A common lumen extends from the handle into and through most of the length of the tip section. In one embodiment the tip section is made of a flexible open-celled foam material with a substantially impermeable outer skin, and in this case the tip section can be contracted, or stretched lengthwise to reduce its diameter, for ease of insertion, then re-expanded to its nominal and working configuration prior to insertion of a radiation source into the lumen and irradiation of tissue surrounding the tip section.

摘要： A charged particle beam (e.g., ions or electrons) apparatus including two electrostatic focusing lenses and an electrode having a diameter limiting aperture positioned between the lenses is further provided with two electrode assemblies which interact with an extractor electrode and with a source of charged particles such that the trajectories of the particles in the beam passing through the second of the two assemblies are substantially parallel. This feature and other disclosed improvements facilitate the production of a substantially monoenergetic beam which under a first set of conditions can be focused to provide a small-diameter, spherical-aberration limited beam and which under another set of conditions, can be focused to provide a high current beam.

摘要： The radial dose function of an electronic x-ray brachytherapy source is flattened by filtering with transition metals in the fourth row of the periodic table, i.e. titanium through nickel. Titanium-walled applicator devices of small diameter, under 10 mm, and with wall thicknesses of about 0.2 mm to 0.6 mm, are disclosed. The walls can be of titanium or alloys thereof, providing adequate strength and flattening the radial dose function curve particularly for x-rays in an energy range of about 45 kV to 55 kV.

摘要： Methods and apparatus are described for irradiating living tissue via a cavity or lumen, using an inflatable balloon applicator. In a preferred embodiment the applicator balloon has a balloon skin with x-ray contrast material in relatively low concentration, so that an outline of the balloon will appear sharply when imaged externally. In another preferred embodiment the balloon catheter has a drain for withdrawing liquids from the cavity, which may include channels or texture on the exterior of the balloon. Methods are described for using a switchable miniature x-ray tube, variable as to voltage and current, to achieve accuracy in an isodose profile.

摘要： A device, system and method for administering radiation therapy to a tissue surface of a patient utilizes an applicator capable of controlled movement and repositioning over a selected area of tissue, under the control of a computer or controller. A servo-controlled manipulator can effect a raster scan of the desired area, such as an area of the skin, and this can be in any desired pattern such as serpentine, spiral, parallel but unidirectional, or irregular patterns. Preferably a third direction of control is included, i.e. a depth direction, with an appropriate form of depth sensor, a signal from which can be used to adjust the radiation source so that radiation of the tissue surface is consistent over varied contoured.

摘要： An applicator for brachytherapy radiation avoids over-radiation in the distal axial direction from a source positioned in the applicator, by attenuating distal axial radiation which tends to over-radiate, causing a “hot spot” in tissue in the axial direction, when the radiation travels through air space in the lumen.

摘要： A miniature x-ray tube has an anode assembly capable of transmitting x-rays through the anode and over a wide angular range. The anode is in the shape of a cone or truncated cone with an axis on the x-ray tube frame axis, formed of low-Z material with high thermal conductivity for heat dissipation. A target material on the anode body is in a thin layer, which may be approximately 0.5 to 5 microns thick. In one embodiment a tube evacuation exhaust port at the tail end of the anode assembly forms a cavity for a getter, with a pinched-off tubulation at the end of the cavity.
