comparison of metrezoate-labeled gallium transmission with different 50, 60 and 75% concentrations in malignant lymphatic cells

radiation therapy is considered as one of the main methods in cancer treatment. in this method, determination of exact location and geometric properties of tumor is necessary for treatment planning that leads to increased accuracy and output of treatment and reduction of healthy tissue dose. for this purpose, the aim of the present study has been physiological transmission of gallium as a pharmaceutical carrier which is bonded with an x-ray opaque media for treatment of lymphatic tumor via smart radiotherapy method (photoelectron therapy). using radiography or ct scan has provided determination of geometric features of tumor.
