Radiation Oncology/Simulation devices

Patient immobilization devices BOHAP - Blue OverHead Arm Positioner Karolinska Hospital (Sweden)(1998-2001) -- head mask vs head-and-neck mask setup Randomized. 241/260 patients. H&N cancers excluding NPC. Arm 1) Head mask vs. Arm 2) Head-and-shoulder mask. Both Posicast thermoplastic masks. Assessed reproducibility (port films and table positions), patient tolerability (fit, pain, movement within, claustrophobia), and skin damage 2005 15629618 -- "Randomized trial on two types of thermoplastic masks for patient immobilization during radiation therapy for head-and-neck cancer." (Sharp L, Int J Radiat Oncol Biol Phys. 2005 Jan 1;61(1):250-6.) Outcome: No difference in reproducibility of setup Toxicity: Claustrophobia head mask 45% vs. head-and-shoulder masks 58% (SS), otherwise no difference in tolerability. Skin toxicity Grade 3 head mask 21% vs. head-and-shoulder mask 39% (SS) Conclusion: Smaller head masks reduced claustrophobial and skin reactions, without compromising reproducibility of the setup External links Medtec products patient positioning and fixation devices bolus and patient shielding skin markers, rectal and vaginal markers, tattooing Other: Medtec - Radiation detector (doesn't have anything to do with simulation)
