Speckle Noise Removal By Genetic Neuro-Fuzzy System In Sonography Images

Ali Rafiei; Mohammad Hasan Moradi; Mohammad Reza Farzaneh

Volume 1, Issue 2 , June 2007, Pages 83-93

  A new filter was designed and approved for speckle noise removal in sonography images. In this filter, a new idea is used by using neural network learning, fuzzy information and genetic algorithm optimization. The multi-layer perceptron neural network with binary weights is used in this filter. The neighborhood ...  Read More

Determination Of Elastic Modulus Of Artery Wall By Modeling Of Artery Wall And Blood Flow

Mehdi Maerefat; Asghar Khoushkar Shalmani; Manije Mokhtari Dizaji

Volume 1, Issue 2 , June 2007, Pages 95-104

  Modeling of blood flow and arterial wall in large arteries such as carotid artery, using ultrasonic measurements, allows non-invasive evaluation of clinically interesting homodynamic variables. In this study, a nonlinear mathematical model for the pulsatile arterial flow is proposed using the approximation ...  Read More

Effect Of Liquid Phase Concentration On Setting Time And Compression Strength Of Hydroxyapatite Bone Cement

Seyed Mahmoud Rabiei; Fathollah Moztarzadeh; Mehran Solati Hashjin; Saeed Hesaraki

Volume 1, Issue 2 , June 2007, Pages 105-110

  In this research, the influence of NaH2PO4.2H2O with different concentrations on setting time and compressive strength of bone cement based on hydroxyapatite was investigated. Hydroxyapatite cement is of calcium phosphate bone cements, which can be considered as the best substitute for hard tissues. ...  Read More

Blood Flow Simulation And Comparing Of Hemodynamic Factors In Aorta-Coronary And Coronary-Coronary Bypasses

Farzan Ghalichi; Majid Ahmadlouy Darab; Ahmad Ramezani Saadatabadi

Volume 1, Issue 2 , June 2007, Pages 111-117

  In order to compare the aorta-coronary and coronary-coronary bypasses blood flow fields in the Endto-Side Anastomosis, we carried out numerical simulation of three dimensional pulsatile blood flow for 50% stenosis by using FLUENT 5.2.3 software. In this study, the blood was assumed to be as the Newtonian, ...  Read More

An Edge Detection Method Based On Computational Model Of Simple Cells In Primary Visual Cortex

Naser Mehrshad; Mohammad Hasan Ghasemian Yazdi

Volume 1, Issue 2 , June 2007, Pages 119-129

  Simple cells in primary visual cortex respond to the local, oriented edge segments within their receptive fields. In this study, we present a new edge detection method based on the computational model of these cells. Firstly, the response of a set of simple cells for a number of different preferred orientations ...  Read More

A 3d Finite Element Analysis Of The Second Cervical Vertebra (Axis) To Study The Odontoid Fracture

Mohammad Haghpanahi; Ali Gorginzadeh; Saba Sohrabi

Volume 1, Issue 2 , June 2007, Pages 131-136

  Considering the life threatening consequences of the cervical spine injuries, the study of its biomechanical behavior has become important. The most common axis (second cervical vertebra) injury is called odontoid fracture, the majority of which is type II or dens fracture. In this study, an exact 3D ...  Read More
