Introduction: Total body irradiation (TBI) is a form of external beam radiotherapy which is used in conjunction with chemotherapy with the purpose of immunosuppression. Since the target in TBI is the whole body so a uniform dose distribution throughout the entire body during TBI is necessary. As recommended by AAPM dose variation must be within ±10% of prescription dose. A revi...
distortion of the ideal domain shape and size thus making fabrication of fine domains challenging [3]. Poling inhibition (PI) induced by UV laser irradiation [6, 7] in congruent (CLN) and MgO-doped LN can overcome the limitation of EFP by reducing the aspect ratio of the inverted domains allowing for the fabrication of finer domain structures. This method is capable of producing domains with a ...
– By means of layer resolved ion irradiation the mechanisms involved in the irradiation driven modifications of the exchange bias effect in NiFe/FeMn bilayers have been investigated. It is shown that not only the locations of the defects but also the magnetic coupling between both layers during the irradiation process is of crucial importance. This requires an extension of current models accoun...
The purpose of this study is to develop a total body irradiation technique that does not require additional devices or sophisticated processes to overcome the space limitation of a small treatment room. The technique aims to deliver a uniform dose to the entire body while keeping the lung dose within the tolerance level. The technique treats the patient lying on the floor anteriorly and posteri...

Due to the angulation of the breast board used for tangential breast irradiation, additional normal lung tissues are included in the supraclavicular field. This work investigates a method to reduce the lung volume and dose delivered during supraclavicular irradiation for breast cancer. Ten patients included for this retrospective study received chest wall and supraclavicular irradiation followi...
The reliability of sensors that are used to monitor insitu electrochemical corrosion potential (ECP) for water condition of boiling water reactors (BWR) under an irradiation field is quite important [1]. In these sensors, the ion conductivity of yttria stabilized zirconia (YSZ) is utilized to measure the ECP. Therefore, for the accurate estimate of ECP, effects of irradiation on YSZ have to be ...
