Radiation therapy treatment is used in nearly two-thirds of all cancer patients. Accurate targeting of the tumor over the treatment period is critical to effective therapy. Placement of permanent tattoos is the current standard practice to aid in the alignment and targeting of radiation therapy over multiple treatments. Existing tattoo methods involve the use of freehand needle sticks, non-sterile inks, and methods with potential for inaccuracies.

A Mayo Clinic researcher has developed an improved device to reliably and safely place tattoos for radiation therapy treatment alignment. Design features include sterile ink reservoir, retractable safety needle, and single push button deployment. Versions that allow for single tattoo and single patient disposable devices have been described.
