Uniformity of Dose Distribution in Target Volume in Radiotherapy Techniques for Breast after Mastectomy.
Background & Objective: Radiotherapy has a very special significance in the treatment of cancer. Beam radiation therapy using photons and electrons produced by a linear accelerator is used extensively in the treatment of breast Cancer. In this article, In addition to providing a description of t...

| description | Background & Objective: Radiotherapy has a very special significance in the treatment of cancer. Beam radiation therapy using photons and electrons produced by a linear accelerator is used extensively in the treatment of breast Cancer. In this article, In addition to providing a description of three techniques of radiotherapy in the treatment of breast cancer, has been Evaluating the effectiveness of this method in the base of uniformity of the dose distribution in the target volume in breast cancer as an important factor in the effectiveness of treatment by radiation.Materials & Methods: Photon, electron and arc Techniques in radiotherapy have been implemented practically using phantom trunk and EDRII films. At the time of practical Techniques, films were placed between the slice of the phantom and were irradiated under selected conditions and the data of these images are analyzed by MATLAB software.Results: Studies show that as a result of using adjacent fields in whole radiotherapy techniques, Parts of the target volume received dose twice or more than the prescribed dose. Meanwhile, by the photon dose technique, rate of receiving dose is more uniform and closer to the prescribed dose.Conclusion: According to scientific studies done by different protocols in breast radiotherapy, tangential photon technique has very less overlap of the field by comparison to other methods and more uniform dose distribution than the prescribed dose .In The base of this research results can be announced the photon techniques in breast cancer treatment was preferred over other methods. |
