    A Short Synthesis Concerning Biological Effects and Equivalent Doses in Radiotherapy

    Cyril Voyant* and Daniel Julian

    The limits of classical equivalent computation based on time, dose, and fractionation (TDF) and linear quadratic models have been known for a long time. Medical physicists and physicians are required to provide fast and reliable interpretations regarding the delivered doses or any future prescriptions relating to treatment changes.

    Inter-Observer Variability of a Commercial Patient Positioning and Verification System in Proton Therapy

    Yuanshui Zheng* and Xiaoning Ding

    Purpose: Accurate patient positioning is crucial in radiation therapy. To fully benefit from the preciseness of proton therapy, image guided patient positioning and verification system is typically utilized in proton therapy. The purpose of this study is to evaluate the inter-observer variability of image alignment using a commercially available patient positioning and verification system in proton therapy.

    Using Mathematical Procedure to Compute the Attenuation Coeffi cient in Spectrometry Field

    Mohamed Elsafi, Mona. M. Gouda, Mohamed. S. Badawi*, Abouzeid. A. Thabet, Ahmed. M. El-Khatib, Mahmuod. I. Abbas and Kholud. S. Almugren

    In gamma-ray spectrometry, the analysis of the environmental radioactivity samples (soil, sediment and ash of a living organism) needs to know the linear attenuation coefficient of the sample matrix. This coefficient is required to calculate the self-absorption correction factor through the sample bulk.

    Empirical formulae for calculating γ-ray detectors effective solid angle ratio

    Ahmed. M. El Khatib, Mohamed. S. Badawi*, Mohamed. A. Elzaher, Mona. M. Gouda, Abouzeid. A. Thabet, Mahmoud. I. Abbas and Kholud. S. Almugren

    Determination of the detector efficiency using volumetric cylindrical sources is very important in various scientific and industrial fields, especially in the field of quantitative analysis. To calculate the absolute activity of any sample, the full-energy peak efficiency (FEPE) of the detector is needed. By applying the efficiency transfer method, the FEPE of the detector would be determined easily without using the standard sources. This approach depends on two main factors.

    New Approach for Analysing the Discrepancy of Pretherapeutic Tc-99m and Intra-therapeutic I-131 uptake in Scintigraphies of Thyroid Autonomies using a Parametric 3D Analysis Program

    Maaz Zuhayra, Marlies Marx, Ulrich Karwacik, Yi Zhao and Ulf Lützen*

    Introduction: Radioiodine therapy is a standard procedure in thyroid autonomy treatment. Discrepancies in the visual comparisons of the scintigraphies prepared for this purpose using Tc-99m-O4- and I-131 have been known for years. In this study a new method is used to calculate and perform a quantitative comparison of both uptakes using subtraction analysis and 3D imaging. The results and their causes are discussed together with practice-relevant conclusions for better clinical results.
