Diode 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 کاملCT‐based analysis of dose homogeneity in total body irradiation using lateral beam
A computed tomography (CT) based treatment planning system for total body irradiation (TBI) is presented and compared with the commonly practiced lateral treatment delivery. The TBI regimen has been proved to be an essential conditional regimen for patients undergoing bone marrow transplantation. The advantage of the TBI regimen with bone marrow transplantation (BMT) in hematological malignanci...
متن کاملDose Homogeneity of the Total Body Irradiation in vivo and in vitro confirmed with Thermoluminescent Dosimeter
INTRODUCTION Although radiotherapy is generally used as a local modality, it also can be used as systemic modality in number of occasions. Indications of total body irradiation (TBI) or whole body irradiation are immune suppression prior to bone marrow transplantation (immunologic diseases, aplastic anemia), eradication of malignant cells (leukemia, lymphoma and some solid tumor), and eradicati...

متن کامل3D heterogeneous dose distributions for total body irradiation patients
One major objective of total body irradiation (TBI) treatments is to deliver a uniform dose in the entire body of the patient. Looking at 3D dose distributions for constant speed (CstSpeed) and variable speed (VarSpeed) translating couch TBI treatments, dose uniformity and the effect of body heterogeneities were evaluated. This study was based on retrospective dose calculations of 10 patients t...
