Design of an Innovative Water Filter for Total Body Irradiation
Total Body Irradiation (TBI) is a radiological therapy mainly used for patient conditioning before bone marrow transplantation. Basically, the therapy consists in delivering a suited X-ray dose to the entire body of the patient. Achieving a uniform dose over the whole body is one of the major problems because of variations in thickness and density of patient’s tissues. This paper presents the d...
متن کاملIntensity-modulated Total Body Irradiation (TBI) with TomoDirect™
BACKGROUND The new TomoDirect™ modality offers a non-rotational option with discrete beam angles. We have investigated this mode for TBI with the intention to test the feasibility and to establish it as a clinical routine method. Special foci were directed onto treatment planning, dosimetric accuracy and practical aspects. PATIENTS AND METHODS TBI plans were calculated with TomoDirect™ for a ...
متن کاملTotal Body Irradiation (TBI) using Helical Tomotherapy in children and young adults undergoing stem cell transplantation
BACKGROUND Establishing Total Body Irradiation (TBI) using Helical Tomotherapy (HT) to gain better control over dose distribution and homogeneity and to individually spare organs at risk. Because of their limited body length the technique seems especially eligible in juvenile patients. PATIENTS AND METHODS The cohort consisted of 10 patients, 6 female and 4 male, aged 4 - 22 y with acute lymp...
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 کاملInvestigation on using high‐energy proton beam for total body irradiation (TBI)
This work investigated the possibility of using proton beam for total body irradia-tion (TBI). We hypothesized the broad-slow-rising entrance dose from a monoen-ergetic proton beam can deliver a uniform dose to patient with varied thickness. Comparing to photon-based TBI, it would not require any patient-specific com-pensator or beam spoiler. The hypothesis was first tested by simulating 250 Me...
