the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Background: Magnetic resonance imaging (MRI) has long been considered a perfect imaging study for evaluation of shoulder pathologies despite occasional discrepancies between MR reports and arthroscopic findings. In this study we aim to evaluate impact of imaging center as an indicator of image quality on accuracy of MRI reports in diagnosis of rotator cuff tendon pathologies. Methods: We re...
introduction: hemothorax is one of the most prevalent injuries caused by thoracic traumas. early detection and treatment of this injury is of utmost importance in prognosis of the patient, but there are still controversial debates on the diagnostic value of imaging techniques in detection of hemothorax. therefore, the present study aimed to evaluate the diagnostic value of chest ultrasonography...
Introduction: Glioma is the most common type of brain malignancy among adults. Treatment for this type of tumor involves surgery, radiotherapy, and in higher grades, including chemotherapy. The precise grading of the tumor is critical for treatment planning and prognosis determining. Considering the possibility of problems such as errors in tissue sampling during surgery, as we...
background: breast cancer is third order malignancy in women among other malignancies. various studies showed that incidence of breast cancer can be lower down by early detection of breast cancer. mammographic screening is considered more effective modality in detecting early stage breast cancer in women who are at elevated risk for breast cancer. the aim of this study is to report the result...
در این پژوهش به منظور برآورد تابش خالص برای مکان یابی نیروگاه های خورشیدی با پردازش تصاویر ماهواره ای در استان کردستان از دو روش sebal و روش solar analysis استفاده شده است در روش sebal از داده های تصاویر ماهواره ای مودیس 2000، 2003، 2006، 2009، 2012 داده های ساعات آفتابی در7 ایستگاه سینوپتیک در سطح استان کردستان ( داده های روزانه) و برای روش solar analysis از تصاویر دم منطقه با قدرت 30 و 90 متر...
Coronavirus (COVID-19) is spreading rapidly around the world and, as of October 2020, more than 1,966,000 people have been infected in 200 countries. Early detection COVID-19 essential for provision and protection HIV-negative adequate health care patients. To do this, we developed an automated diagnostic program from pneumonia (CPA) obtained chest tomography (CT). We propose, particular, Noise...
background: ultrasonography is an imaging method which, due to its relative economy, is becoming more widely available in regions of the world where fasciola hepatica infection occurs most frequently. in this report, we describe the sonographic findings of hepatic lesions in patients with fascioliasis to help confirmation of the sonographic characteristics of this disease and thus aid in its di...
