A new method for ideal dose distribution of two adjacent fields for external beam radiation therapy
Abstract Background: Adjacent treatment fields are commonly used in external beam radiation therapy, such as mantle and inverted-Y fields for the treatment of Hodgkin’s disease and craniospinal fields used in the treatment of medulloblastoma and head and neck tumors when the lateral neck fields are placed adjacent to the anterior supraclavicular field. In each of these situations, there is a p...
متن کاملExternal beam radiation therapy for prostate cancer.
Men with non-metastatic prostate cancer have many treatment options. For over 35 years, radiation therapy has been a mainstay of treatment for this disease. With improvements in technology and better use of pretreatment prognostic factors, such as prostate specific antigen level and Gleason score, biochemical and clinical results have steadily improved. This article reviews the current status o...
متن کاملRadiation optic neuropathy after external beam radiation therapy for acromegaly.
For diagnosing radiation optic neuropathy (RON) ophthalmological and imaging data were evaluated from 63 acromegalic patients, irradiated between 1967 and 1998. Two patients developed RON: one patient in one optic nerve 10 years and another patient in both optic nerves 5 months after radiation therapy. RON is a rare complication after external beam radiation therapy for acromegaly, which can oc...

متن کاملDosimetric impact of computed tomography calibration on a commercial treatment planning system for external radiation therapy.
The Hounsfield units into density conversion for a commercial treatment planning system (TPS) is discussed. The impact of an average calibration table provided by the manufacturer on computed doses was investigated when a customer calibration could not be included in the TPS. The maximum error determined on the computed monitor units per Gy was found to be about 2%, being below 1% on average. T...
