Background and Aim: Generally, in patients with cervical cancer, careful preliminary evaluation is necessary for avoiding improper surgical procedures and making effective clinical decisions for treatment. The aim of this study was to determine surgeons’ errors, which necessitate a combination of surgery and radiotherapy for cervical cancer patients.    Methods: In this retrospective study, med...

Introduction: The accuracy of the patient setup and tumor location are major factors that determine the efficacy of radiotherapy treatment planning. In the prostate radiotherapy, reproducibility of the prostate location for each treatment fraction is problematic owing to varying filling of the rectum and bladder. According to this, the aim of this study was to measure the inte...

PURPOSE The purpose of this article was to highlight the importance of data management systems in radiotherapy. METHODS We performed a database search to review the errors or potential errors in radiotherapy planning and delivery which could be prevented in case of using the DICOM communication system. RESULTS We registered the following rates of errors: 1) Errors caused by manual rewriting...

Introduction: Despite growing interest in the use of magnetic resonance imaging (MRI) in the external radiotherapy design process (RT), Computer Tomography (CT) remains a gold standard and is regarded as a basic imaging modality in radiotherapy. MRI shows the high contrast in soft tissues without any radiation exposure to patients. As a result, MRI is used in functional tissue ...

Introduction: Successful radiotherapy requires the precise application of a radiation dose to cancerous tissue, which can be achieved by the design of proper treatment methods by radiotherapy physicists. Tasks performed by radiotherapy physicists include verifying the accuracy of dose calculations, correct treatment planning and the proper functioning of accelerators. They are...

In vivo dosimetry seems an appropriate method for quality assurance in radiotherapy with CO-60, which can be considered as a routine program in radiotherapy centers. In this study, entrance and exit dose in tangential fields were measured in phantom for 30 breast cancer patients by using TLD in radiotherapy section of Imam Khomeini Hospital. TLD crystals were calibrated against SSDL (Secondary...
