Helical Tomotherapy® is a Safe and Feasible Technique for Total Scalp Irradiation
Angiosarcoma of the scalp is a rare aggressive tumor that affects elderly patients. Chemoradiation is the treatment of choice for multicentric and extensive disease. The shape of the scalp represents a dosimetric challenge in terms of achieving a homogeneous concave dose distribution with coverage of the entire target volume and an acceptable organs-at-risk sparing. We report a case of an 81-ye...
متن کاملA simpler method for total scalp irradiation: the multijaw‐size concave arc technique
The lateral electron-photon technique (LEPT) and intensity-modulated radiation therapy (IMRT) are commonly used for total scalp irradiation. However, the treatment planning and irradiation are laborious and time-consuming. We herein present the multijaw-size concave arc technique (MCAT) as a total scalp irradiation method that overcomes these problems. CT datasets for eight patients previously ...
متن کاملVirtual bolus for total body irradiation treated with helical tomotherapy
Intensity-modulated radiation therapy (IMRT) for total body irradiation (TBI) is practiced in several centers using the TomoTherapy System. In this context the planning target volume (PTV) is the entire body including the skin. A safety margin in the air surrounding the body should be added to take into account setup errors. But using inverse planning, over-fluence peak could be generated in th...
متن کاملAPPLICATION OF MICROWAVE IRRADIATION TECHNIQUES FOR THE WITTING REACTION
The Wittig reaction rate can be dramatically enhanced by irradiation of the reaction mixture containing an aldehyde or ketone; methoxymethyl(triphenyl)phosphonium chloride, potassium t-butoxide, and t BuOH with a commercial microwave oven. Carbonyl compound are converted to Witting products within three min. in good yields.
متن کاملVolumetric arc therapy for total scalp irradiation: case report for a recurrent basal cell carcinoma of the scalp
Total scalp irradiation may be used to treat numerous conditions including squamous and basal cell carcinomas. These conditions are relatively uncommon and patients are frequently treated with palliative intent. In this report, we describe a volumetric arc therapy technique using photon beams for curative intent in an 84 years old patient with recurrent basal cell carcinoma of the scalp. Dose w...
