Background: A thoracic curve degree of greater than 45° leads to thoracic hyperkyphosis, and its common treatment method is orthotic treatment. The acceptance rate of spinal orthosis depends on in-brace correction, patient`s compliance and quality of life. Objective: In this study, we aimed to compare in-brace correction, compliance and quality of life in patients with thoracic hyperkyphosis ...

to investigate the effect of preprocessing techniques including contrast enhancement and illumination correction on retinal imagequality, a comparative study was carried out. we studied and implemented a few illumination correction and contrast enhancementtechniques on color retinal images to find out the best technique for optimum image enhancement. to compare and choose thebest illumination c...

Background: In this study, Quantitative 32P bremsstrahlung planar and SPECT imaging and consequent dose assessment were carried out as a comprehensive phantom study to define an appropriate method for accurate Dosimetry in clinical practice. Materials and Methods: CT, planar and SPECT bremsstrahlung images of Jaszczak phantom containing a known activity of 32P were acquired. In addition, Phanto...

Introduction: In nuclear medicine imaging, detection of the scattered photons along with the primary photons is one of the major problems that can lead to a decrease in ddiagnostic accuracy. Therefore, use of a suitable scatter correction method can help to improve of the image quality and increase of diagnostic accuracy. The aim of this study is evaluation of five energy wind...

The present study is an attempt to explore any significant relationships between learners’ preferences for error correction, demotivation, and language proficiency (LP). One hundred Iranian EFL students, including both males and females, studying at the departments of foreign languages of Shahid Bahonar University of Kerman and Tehran University took part in this study. In order to obtain the r...

The present study was aimed at investigating intermediate Iranian EFL learners’ feedback preferences on their L2 writing and examining the possible differences between learners with entity and incremental language mindsets with respect to their feedback preferences. To this end, 150 EFL learners were recruited from several language institutes in Isfahan, Iran, and their language proficiency lev...

  Introduction: Attenuation correction is a useful process for improving myocardial perfusion SPECT and is dependent on activity and distribution of attenuation coefficients in the body (attenuation map). Attenuation artifacts are a common problem in myocardial perfusion SPECT. The aim of this study was to compare the effect of attenuation correction using different a...

In this paper, we improve b-spline collocation method for Benjamin-Bona-Mahony-Burgers (BBMB) by using defect correction principle. The exact finite difference scheme is used to find defect and the defect correction principle is used to improve collocation method. The method is tested on somemodel problems and the numerical results have been obtained and compared.
