摘要： A particle analyzer in which tagged particles to be analyzed are drawn through a suspended capillary tube where a predetermined volume in the capillary tube is illuminated. The illumination scattered by said particles is detected by a detector to count all particles. The fluorescent illumination emitted by tagged particles is detected and the output signals from the fluorescent detectors and scatter detector are processed to provide an analysis of the particles.

摘要： Described here are conformable brachytherapy applicators. The conformable brachytherapy applicators generally follow the contour of tissue surfaces so that distances between radiation sources and target tissues can be precisely determined and radiation dose clouds can be readily shaped. Systems and methods for using the conformable brachytherapy applicators are also described.

摘要： A multi level multileaf collimator employs leaves with leaf tips having a non-square shape in a beam's eye view to improve beam shaping effect and penumbra performance. The multi level multileaf collimator includes a first multileaf collimator in a first level comprising beam blocking leaves longitudinally movable in a first direction, and a second multileaf collimator in a second level comprising beam blocking leaves longitudinally movable in a second direction. The first direction may be generally parallel with the second direction and the leaves of the first multileaf collimator may laterally offset the leaves of the second multileaf collimator. The beam blocking leaves of the first multileaf collimator may comprise an end portion having a non-square shape in a beam's eye view.

摘要： An x-ray tube includes an evacuated envelope, and a cathode assembly and an anode assembly both disposed in the evacuated envelope. The cathode assembly includes a cathode shield, a supporting body disposed inside the cathode shield, and an electron source attached to the supporting body and partially enclosed by the cathode shield. The anode assembly includes a target configured to produce x-rays upon impingement by electrons produced by the electron source. The cathode shield comprises a shield base material and a layer over at least a portion of the base material. The layer comprises an emissivity enhancer having an emissivity greater than the emissivity of the shield base material. The layer may comprise an emissive coating applied on the portion of the base material. Alternatively, the layer may comprise a greened surface formed by a greening process.
