3 ABSTRACT Biological treatment optimization aim at improving radiation therapy by accounting for the radiobiological tumour and normal tissues response properties when optimizing the dose delivery. Generally traditional methods, using only dosimetrical measures, disregard the non-linear radiation response of different tumours and normal tissues. The accumulated knowledge on tissue response to ...
Background: Radiation Pneumonia (RP) is one of the most extensive side effects in Stereotactic Body Radiotherapy (SBRT) of lung cancer. SBRT are performed by means of Intensity Modulated Radiotherapy (IMRT), Intensity Modulated Arc Therapy (IMAT), CyberKnife (CK) or Helical Tomotherapy (HT) treatment methods. In this study, we performed a plan study to determine the plan parameter such as the M...
The Intensity Modulated Radiation Therapy (IMRT) together with Image Guided Radiation Therapy (IGRT) improves radiation therapy for head and neck cancer. On the one hand tumors can be better covered with radiation dose and on the other hand normal tissue can be better preserved. Carefully applied this leads to the same tumor control rate with reduced toxicity compared with conventional radiatio...
Intensity modulated radiation therapy (IMRT) and volumetric intensity-modulated arc therapy (VMAT) are two commonly used modalities to treat lung cancer. VMAT has established increasing interest in treating cancer due to shorter treatment delivery time and less number of monitor units (MUs). The main purpose of this article was to review the relevant current literature on planning studies for l...
Purpose: In the current study, using different radiobiological models, tumor control probability (TCP) and normal tissue complication probability (NTCP) of radiotherapy plans were calculated for three-dimensional conformal radiation therapy (3D-CRT) and intensity modulated radiation therapy (IMRT) of prostate cancer.Methods and Materials: 10 prostate plans were randomly selected among patients ...
