SU-E-T-216: A Clinical Dosimetry Analysis of Total Body Irradiation for Leukemia Patients.
PURPOSE Perform a retrospective dosimetry study of total body irradiation (TBI) on leukemia and bone marrow transplant patients. METHODS The in vivo dosimetry data of 129 patients treated with TBI between 2008 and 2011 were retrieved from the database and analyzed. These patients were mostly treated with the regime of a single fraction or 6 fractions with some exceptions of 8-fraction or 2-fr...
متن کاملPatterns of patient specific dosimetry in total body irradiation.
PURPOSE Total body irradiation (TBI) has been used for bone marrow transplant for hematologic and immune deficiency conditions. The goal of TBI is to deliver a homogeneous dose to the entire body, with a generally accepted range of dose uniformity being within ± 10% of the prescribed dose. The moving table technique for TBI could make dose uniform in whole body by adjusting couch speed. However...
متن کاملDiode calibration for dose determination in total body irradiation
Background: Total Body Irradiation (TBI) is different from standard radiotherapy in many aspects, so it is not easy to predict the delivered dose to the patient under TBI treatment. Diode dosimetry procedures for surface dose reading can help to define variations of the actually delivered dose from the prescribed one. The aim of this study was to describe the measurements made to calib...
متن کاملFabrication of anthropomorphic phantoms for use in total body photon irradiation and total skin electron irradiation studies
Introduction: Total Skin Electron Therapy (TSET) and Total Body Irradiation (TBI) are kinds of treatment which use electron and photon beams to treat special types of cancers. The aim of these techniques are to deliver uniform dose to the entire skin while minimizing delivered dose to organs at risk. To check the homogeneity of dose delivery in TBI and TSET, using a humanoid ph...
متن کاملTotal body irradiation for myelomatosis.
In the first myeloma trial of the M.R.C. working party on leukaemia in adults the deaths that have occurred can be attributed to unrelated diseases (5%h-for example, cosonary thrombosis, etc.); causes indirectly telated to the tumour (80,for example, pneumonia due to the immune paresis); no obvious response of the tumour to treatment (27/); and finally relapse of the tumour after an initial res...
