A study of the possibility of using diode lasers in tissue burn treatment
Abstract: The photobiostimulation is one of the interesting laser applications in medicine. Practically in Iraq there is no real attention paid to these medical applications of laser and there is no much knowledge about the benefits of the laser biostimulation of skin and tissue burn healing. This work focused on studying the effect of diode laser (637-785nm) with two different powers on the burn healing.
Finite element analysis of the total hip joint prostheses against fatigue fracture
Abstract: Forces applied to the implant due to human activity generate dynamic stresses varying in time and resulting in the fatigue failure of implant material. Therefore, it is important to ensure the hip prostheses against static, dynamic and fatigue failure. This study about two types of implants; the Austin Moore, cemented Thompson, and cementless Thompson hip replacements. The three dimensional solid models were built using AutoCAD 2007 software and then transferred to the finite element software (ANSYS Workbench).
Study of breast tumor diagnosis using optoacoustic technology
Abstract: Photonic technology plays an important role in the development of new medical diagnostic and therapeutic instruments. Readily available compact solid-state lasers and various types of light sources allow one to examine tissues in a clinical environment using new and emerging photonic technologies. The objective of this work is to provide theoretical and experimental procedure of laser optoacoustic imaging to address breast cancer diagnosis using thermo-acoustic imaging principles, where the analytical simulation and experimental results have been represented.
Design and implementation of FPGA download interface
Abstract:The FPGA download interface is a major problem in Iraq due to the shortage of resources and components in the electronic field which leads to simulate most projects in Iraq. The aim of the project is to design and implement an interface circuit to configure the Field Programmable Gate Array (FPGA) by downloading the configuration file from the computer to the FPGA via the designed circuit. For this the Parallel Port in the Enhanced mode is used to implement the downloading operation and to debug the downloaded file in the FPGA .
A comparative analysis of blood flow measuring methods
Abstract:The purpose of this thesis is to serve as a general introduction to the blood flow physics and blood flow measuring methods, and as a comparative study and analysis for these methods. Blood flow is an important concept in medical field; it represents the function of the heart and the blood vessels of the body. Any abnormality in the heart or blood vessel will be expressed as change in the blood flow velocity from the assumed normal value.
The biomechanics and modeling control of human eye movements
Abstract: Today science has witnessed major developments and rapid increase in ecent creations and inventions in all fields including medical engineering, which has witnessed a marked improvement in human creations that serve this field and explain the design of the mechanical movement of the human eye, which consists of three movements, primary and secondary and tertiary. A biomechanical model will be modified upon a homomorphic saccadic eye movement model by adding and calculating the mass of eye and the elasticity of eye tendon and take a primary position only.
Tracking methods of stone in extracorporeal shock wave lithotripsy
Abstract:The efficiency of the extracorporeal shock wave lithotripsy treatment depends to a great extent on the capability to focus the shock waves on the stone, so to achieve this goal, recognition of the stone and tracking it is essential for good treatment. Two algorithms were proposed to track the renal stone; their results were compared, to determine the most successful among them.
