  • Method of forming an injectable radioactive composition of a carbon encapsulated radioactive particulate
    Patent number: 8778300
    Abstract: A method of forming an injectable radioactive composition, the method comprising the steps of: (a) depositing a solid form of technetium onto a carbon crucible; (b) preheating the solid form of technetium to remove any carrier; (c) plasma ablating the technetium and portions of the carbon crucible; (d) allowing the carbon and technetium metal to co-condense from the gas phase to produce a nanoparticle composite aerosol in an inert gas; (e) dispersing the nanoparticle composite in water containing a low concentration of surfactant using an electrostatic precipitator; (f) size fractionating the nanoparticle dispersion by filtration with hydrophilic membranes of known pore size.
    Type: Grant
    Filed: April 28, 2006
    Date of Patent: July 15, 2014
    Assignee: The Australian National University
    Inventors: William Martin Burch, Timothy John Senden, Ross Wentworth Stephens, Beverley Ann Browitt

  • Process for the production of a radioactive aerosol
    Patent number: 7722856
    Abstract: A method for forming an inhalable isotope compound suitable for use in patient medical diagnosis, the method comprising the steps of: (a) electrolytic loading of a carbon crucible with the isotope; (b) sublimating any isotope carrier in the crucible; (c) ablating the isotope in a carbon crucible, forming an ablation aerosol; (d) directly delivering the aerosol for immediate use by a patient. The isotope can comprise technetium.
