Abstract
The present invention provides a device for delivering an electron beam providing radiation treatment to subcutaneous cells. The device includes a hollow needle having a proximal and a distal end for respectively directing the electron beam therethrough. The proximal end of the needle is adapted for attachment to the source of the electron beam. A scattering target for the electron beam is also provided. The scattering target is adapted for positioning at the distal end of the hollow needle whereby the distal end of the hollow needle is capable of insertion directly to the subcutaneous cells for radiation treatment. The present invention also provides a system for providing electron radiation treatment directly to subcutaneous cells that includes a source of an electron beam of selectively variable content and energy levels effective for electron radiation treatment and a hollow needle with a scattering target as described above. The present invention also contemplates a method for providing electron radiation treatment directly to subcutaneous cells.
