摘要： The present invention is directed to a kit for delivering x-rays to the interior surface of a body cavity. The kit includes an x-ray source and an x-ray source guidance tube. The guidance tube includes an inflatable inelastic balloon disposed about and affixed at its distal end such that when inflated, the central axis of the balloon is coaxial with and is disposed about the central axis of the tubular element. Inflation and deflation of the balloon is controllable from the proximal end of the tubular element. The x-ray source may include an electron activated target for generating x-rays in response to electrons incident on the target. The x-ray source may also includes means for generating an electron beam and steering the beam so that it is incident on the target. The target end is slidably positionable within an interior channel of the source guidance tube.

摘要： The present invention is directed to an x-ray source for irradiating a surface defining a body cavity in accordance with a predetermined dose distribution. The source comprises a housing, an elongated tubular probe, a target assembly, and an inflatable balloon. The housing encloses an electron beam source and includes elements for generating an electron beam along a beam path. The tubular probe extends along a central axis from the housing about the beam path. The target assembly extends along the central axis and is coupled to the end of the probe distal from the housing. The target assembly includes a target element is positioned in the beam path. The target element is adapted to emit x-rays in response to electrons incident thereon from the beam. The probe tip assembly and associated control electronics include elements for positioning the target element in the beam path, and is substantially x-ray transparent. The balloon is affixed to the distal end of the probe and is inflatable so that when that probe end is inserted into a body cavity, the balloon may be inflated to stretch the cavity to a known shape. Positioning the probe tip inside the inflated balloon allows delivery of a uniform, or other desired, dose of radiation to the surface defining a body cavity.

摘要： A support system for a radiation treatment system includes a rotatable extension arm extending from a vertical shaft and a rotatable counterbalance extending diametrically opposed to the extension arm from the vertical shaft. The vertical shaft is rotatably supported by a support base. The support base may include a damping mechanism to damp the rotational motion of the vertical shaft relative to the support base, wherein the damping force is preferably proportional to the velocity of the vertical shaft. The radiation treatment system is suspended from a cable extending from a distal end of the extension arm. The extension arm can be formed from a first arm extending from the vertical shaft and a second arm rotatably coupled to the first arm in order to permit the radiation treatment system to be moved in horizontal direction. The cable supporting the radiation treatment system can be coupled to a vertical counterbalance weight to allow the vertical position of the radiation treatment system to be adjusted. In addition, mass of the vertical counterbalance weight can be adjusted to compensate for attachments which may be used with the radiation treatment system during treatment. The radiation treatment system can be supported to permit rotation about a horizontal axis that extends through the center of mass of the radiation treatment system. In addition position of the horizontal axis of rotation relative to the center of mass of the radiation treatment system can be adjusted to compensate for attachments which may change the center of mass of the radiation treatment system.
