CT‐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 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 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 کاملTotal body irradiation dose optimization based on radiological depth
We have previously demonstrated the use of Eclipse fluence optimization to define aperture sizes for a novel aperture modulated translating bed total body irradiation (TBI) technique. The purposes of the present study were to identify, characterize, and correct for sources of error inherent in our previous fluence optimization technique, and to develop a clinically viable fluence optimization m...
