Abstract
Radiation shielding devices are provided herein. In particular, the devices provided herein can be adapted to shield radiation emitted by one or more radioactive brachytherapy seeds contained within, for example, a vial or a cartridge.
Claims39
A radiation shielding device configured to engage a brachytherapy seed holding device, wherein:
- a) said shielding device comprises a member having an interior surface and an exterior surface;
- b) said seed holding device defines an external screw thread;
- c) said interior surface of said member defines an internal screw thread configured to engage said external screw thread;
- d) said seed holding device comprises a compartment configured to retain a brachytherapy seed;
- e) said member extends over at least a portion of said compartment when said internal screw thread is engaged with said external screw thread;
- and f) said member defines an opening in a wall of the member extending between said interior surface and said exterior surface such that there is no direct line of sight from the exterior of said member through said opening to said compartment when said shielding device is engaged with said seed holding device.
3 more elements
A radiation shielding device configured to retain a brachytherapy seed holding device, said shielding device comprising:
- a) a first member having a first interior surface, a first exterior surface, and a first mating edge, said first mating edge defining a protrusion, and b) a second member having a second interior surface, a second exterior surface, and a second mating edge, said second mating edge defining a recess configured to receive said protrusion, wherein said first member defines a first opening in a wall of the first member extending between said first interior surface and said first exterior surface, such that when said shielding device contains at least a portion of a seed holding device, there is no direct line of sight from the exterior of said first member to said portion of said seed holding device.
