[ 1 ] - Dosimetric Effects of Rotational Setup Error in Volumetric Modulated Arc Radiotherapy on Brain Tumor Patients
Introduction: This study examined the dosimetric effects based on the rotational setup error to correct patient setup errors occur during volumetric modulated arc radiotherapy (VMAT) for brain tumor patients. Material and Methods: This study included 1129 cases of cone beam computed tomography (CBCT) images obtained from 46 brain tumor patients, who experienced VMAT and used the 6DoF (degree o...
[ 2 ] - Performance Evaluation of Diagnostic X-Ray Equipment Regarding the Hospital Size in the Republic of Korea
Introduction: The Republic of Korea has developed a national standard based on which diagnostic X-ray equipment must be tested every 3 years. Accordingly, the performance of X-ray equipment used in all hospitals is evaluated by national certification bodies in compliance with the safety management regulations for X-ray equipment. However, if the equipment i...
[ 3 ] - Therapeutic effects of high intensity focused ultrasound for in patients with benign uterine tumors with regard to lifestyle and obstetric characteristics
Background: The present investigation compared the decrease in the volume of benign tumor before and after High Intensity Focused Ultrasound (HIFU) treatment to evaluate the therapeutic effects of HIFU. in terms of Lifestyle and obstetric characteristics of in patients with Benign Uterine Tumors.

[ 4 ] - Usability assessment of cone beam computed tomography with a full-fan mode bowtie filter compared to that with a half-fan mode bowtie filter
Background: In intensity modulated radiation therapy, cone beam computed tomography (CT) has been used to evaluate patients prior to treatment. This study conducted a comparative evaluation of the image reconstruction ability of the clinically used half-fan bowtie filter and the full-fan bowtie filter. Materals and Methods: A CT simulation marker was inserted inside a human phantom, and the pel...
