The induction of thymic lymphomas by whole-body X irradiation with four doses of 1.8 Gy (total dose: 7.2 Gy) in C57BL/6 mice was suppressed from a high frequency (90%) to 63% by preirradiation with 0.075 Gy X rays given 6 h before each 1.8-Gy irradiation. This level was further suppressed to 43% by continuous whole-body irradiation with 137Cs gamma rays at a low dose rate of 1.2 mGy/h for 450 d...

Background: Inclusion of inhomogeneity corrections in intensity modulated small fields always makes conformal irradiation of lung tumor very complicated in accurate dose delivery.Objective: In the present study, the performance of five algorithms via Monte Carlo, Pencil Beam, Convolution, Fast Superposition and Superposition were evaluated in lung cancer Intensity Modulated Radiotherapy plannin...

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...

Despite of the studies on widespread biological effects of irradiation, surprisingly only little number of papers can be found dealing with its in vivo hemorheological impact. Furthermore, other studies suggested that low-dose irradiation might differ from high-dose in more than linear ways. On Balb/c Jackson female adult mice hematological and hemorheological impacts of total body irradiation ...

PURPOSE To investigate the incidence of, and possible factors associated with, seroma formation after intraoperative placement of the MammoSite catheter for accelerated partial breast irradiation. METHODS AND MATERIALS This study evaluated 38 patients who had undergone intraoperative MammoSite catheter placement at lumpectomy or reexcision followed by accelerated partial breast irradiation wi...
