Abstract: A nuclear powered quantum dot light source, having a holder having at least a portion that is a radiolucent and a mixture of quantum dots, a radionuclide, and a radiolucent binder material into which the quantum dots and radionuclide are located. Alpha and/or beta particles from the radionuclide energize the quantum dots and cause them to give off light at one or more predetermined wavelengths.

Abstract: A multimodal source for imaging with at least one of a gamma camera, a positron emission tomography (PET) scanner and a single-photon-emission computed tomography (SPECT) scanner, and at least one of a computed tomography (CT) scanner, magnetic resonance imaging (MRI) scanner and optical scanner. The multimodal source has radioactive material permanently incorporated into a matrix of material, at least one of a material that is a target for CT, MRI and optical scanning, and a container which holds the radioactive material and the CT, MRI and/or optical target material. The source can be formed into a variety of different shapes such as points, cylinders, rings, squares, sheets and anthropomorphic shapes. The material that is a target for gamma cameras, PET scanners and SPECT scanners and/or CT, MRI and/or optical scanners can be formed into shapes that mimic biological structures.
Abstract: A lesion phantom with no inner cold encapsulation. The phantom has a plurality of lesion analogues formed without any encapsulation by a dissimilar material and formed of a matrix of solidified material. A background matrix into which at least one radionuclide is dispersed to form a background level of radioactivity. The background matrix is placed in a container. The background level of radioactivity of the background matrix is different than that of the level of radioactivity of the plurality of lesion analogues.
Abstract: A process for implanting radioisotope ions into a substrate to create a radioisotope source, utilizing the chemical binding of selected ions to the surface of the substrate. Extraneous material not chemically bound to the substrate is removed and the chemically bound ions are diffused below the surface of the substrate in a non-oxidizing environment.
