摘要:
An apparatus and method for treatment of lesions or imperfections in or near exposed anatomic surfaces using low-level ionizing radiation includes a substantially transparent applicator to administer radiation from an energy source to a surface area with the lesion. The applicator is positioned over the lesion to be treated, a treatment plan is created to achieve the desired therapeutic effect to the lesion, and execution of the treatment plan is executed by the energy source. Verification of the treatment to plan and safety methods are disclosed.
摘要:
The radial dose function of an electronic x-ray brachytherapy source is flattened by filtering with transition metals in the fourth row of the periodic table, i.e. titanium through nickel. Titanium-walled applicator devices of small diameter, under 10 mm, and with wall thicknesses of about 0.2 mm to 0.6 mm, are disclosed. The walls can be of titanium or alloys thereof, providing adequate strength and flattening the radial dose function curve particularly for x-rays in an energy range of about 45 kV to 55 kV.
