Abstract
A low attenuation radioactive seed utilizing a core having a fluted or non-circular cross section is utilized for increasing the dose rate, decreasing the dwell times and improving the clinical outcomes by increasing the dose consistency throughout the treatment zone. The fluted or non-circular cross section core would increase the surface area for the deposition of the radioactive substance thereby increasing the therapeutic efficacy of the seed. In addition, the fluted or non-circular cross section may be designed in a manner to reduce photon emission attenuation by reducing the distance an inwardly directed photon would have to travel to traverse the core.
