“…By applying Levenberg-Marquardt algorithm [28] with the formula of D fit = b.net OD + c.net OD n on calibrating curve in Figure 2, the results of fitting curves were as following: f(x)=(0.0113×x^0.0469)+(0.1300×x) (8) Where the matching parameters b and c are 0.1300 and 0.0113. Also the power of nonlinear word (n), and the regression coefficient in the curve function matching to the EBT3 film data acquired as 0.04697 and 0.9989 respectively.…”

“…Besides, the Total Skin Electron Therapy (TSET) was initiated in 1950 for the treatment of T-cell skin lymphoma (CTCL), Kaposi's sarcoma, inflammation of breast cancer and scleroderma [6,7]. 90% of people at the early stages of mycosis fungoid disease (MF) were recovered totally by TSET, while this cannot be achieved with chemotherapy and other methods [8,9]. TSET targets the entire skin and acts at a depth of several millimeters using 6 -10…”

Background:The Total Skin Electron Therapy (TSET) targets the whole of skin using 6 to 10 MeV electrons in large field size and large Source to Surface Distance (SSD). Treatment in sleeping position leads to a better distribution of dose and patient comfort.Objective: This study aims to investigate the uniformity of absorbed dose in the sleeping Stanford technique on the Rando phantom using dosimetry. Material and Methods:It is an experimental study which was performed using 6 MeV electron irradiation produced by Varian accelerator in the AP and PA positions with gantry angles of 318/3, 0 and 41/5 degrees, and RAO, LAO, RPO and LPO with 291/4 gantry angle and 45 degrees of collimator angle in the sleeping position. Results:The results show that the dose uniformity achieved in this technique is in the range of (100 ± 25%) and, the dose accuracy was 6%. Conclusion: Total Skin Electron Therapy (TSET) technique in sleeping positionis very suitable for elderly and disabled patients, and meets the required dose uniformity. Furthermore, the use of a flattening filter is recommended for the more dose distribution uniformity.
