ین پایان نامه با هدف سنتز و شناسایی چهار نوع از نانو ذرات آغاز می شود. نانو ذرات آلوم اکسان از واکنش بوهمیت و کربوکسیلیک اسید مربوطه حاصل شدند. هدف از سنتز این نوع نانو ذرات ساخت غشاهای عامل دار شده با خاصیت آب دوستی و انتخاب پذیری جهت جداسازی روغن از مخلوط های آب و روغن، می باشد. tg-dta، ftir، sem، tem، uv/vis spectrophotometer، digital camera،contact angle measurement goniometer، ultrasonic b...
Methods Data was obtained retrospectively from 28 AIS patients who had finished treatment (27 girls, 1 boy, aged 11-15 (mean 13), Cobb angles 20-44 degrees (mean 31), 21 daytime and 7 nighttime braces.) Patients were labelled ‘progressed’ if their Cobb angle had increased more than 5 degrees by the end of treatment, and ‘non-progressed’ otherwise. A fuzzy model was developed to predict treatmen...
The objectives of this study were: To investigate computer-assisted digital radiographic measurement of Cobb angles in dogs with congenital thoracic vertebral malformations, to determine its intra- and inter-observer reliability and its association with the presence of neurological deficits. Medical records were reviewed (2009-2013) to identify brachycephalic screw-tailed dog breeds with radiog...
Background: Scoliosis is a health problem that causes a side-to-side curvature in the spine. The curvature may have an “S” or “C” shape. To evaluate scoliosis, the Cobb angle has been commonly used. However, digital image processing allows the Cobb angle to be obtained easily and quickly, several researchers have determined that Cobb angle contains high variations (errors) in the measurements. ...
Objective: Accurate measurement of thoracic kyphosis has high value in the evaluation of patients with spinal kyphosis and in assessing the effectiveness of different treatment methods. Recently, Dual Digital Inclinometer (DDI) has introduced as a non-invasive tool that can measure the kyphosis angle. According to available information there is only one published study regarding the validity an...
Background. Idiopathic scoliosis is a three-dimensional deformity of the spine and the trunk. The principle clinical method of estimation of the rotational deformity in the transversal plane of the body is the measurement of the angle of trunk rotation with a scoliometer. The aim of the study was to investigate the relationship between the angle of trunk rotation and the two radiological parame...
STUDY DESIGN Automatic measurement of Cobb angle in patients with scoliosis. OBJECTIVE To test the accuracy of an automatic Cobb angle determination method from frontal radiographical images. SUMMARY OF BACKGROUND DATA Thirty-six frontal radiographical images of patients with scoliosis. METHODS A modified charged particle model is used to determine the curvature on radiographical spinal i...
OBJECTIVE The aim of this study was to formulate an objective clinical and geometric relationship between Cobb angle and the difference between the lengths of convex and concave sides (convexo-concave vertebral difference) of the structural curve in scoliosis. Is it possible to express Cobb angle in such a way that it could be visualized as a length, especially while planning for surgical corre...
Material and methods We have used the Formetric 4D-Dicom II system, which is supplied also with lateral Cobb angle measurement. We have examined 616 patients (432 females and 184 males), age 5 y to 21 y. The patients have been visited clinically by inspection, Adams forward bending test and Perdriolle scoliometer. We have fit, to every patient, 4-8 reflectors on the apex of T1 through L4 spinal...
Methods Nine AIS patients undergoing casting for new braces participated in this pilot study (2 males, 7 females, aged 11-16, Cobb angles 16-44 degrees). An ultrasound scan was used to measure the patient’s (baseline) Cobb angle. The orthotist then used a custom standing Providence system to apply corrective pressures simulating a brace. A second ultrasound scan measured the new (corrected) Cob...
