Use of Deep Learning in Ultrasound Videos to Improve the Automatic Detection of the Nuchal Translucency in the First Trimester of Pregnancy
, M.Sc. Thesis Sharif University of Technology ; Jahed, Mehran (Supervisor) ; Kaveh Vash, Zahra (Co-Supervisor)
Abstract
Identifying and interpreting standard fetal plates in first trimester examinations with two-dimensional ultrasound is a very complex task that requires years of experience. Aside from the challenge to position and direct the probe to required positions, there is an understandable difficultly for inexperienced sonologists to identify the corresponding structures in the emerging images. Automated image processing can be helpful both to the experienced as well as inexperienced operators to confront these challenges. In this study, we used data from three different devices SAMSUNG WS80A, VOLUSON E6, VOLUSON E8, which includes a total of 2230 images to measure the thickness of the space behind...
Investigation, Design and Simulation of Elastography and IOTA Imaging Modes in Ultrasound Systems
, M.Sc. Thesis Sharif University of Technology ; Vosoughi Vahdat, Bijan (Supervisor) ; Kavehvash, Zahra (Supervisor)
Abstract
Ultrasound is one of the most widely used imaging techniques used by physicians and radiologists as a tool. It has many diagnostic and therapeutic uses. In particular, ultrasound imaging is used for prenatal imaging due to relative safety, low cost, nature Non-ionizing, instant display and ease of use by the operator, widely used in many countries around the world. According to the Ministry of Health, ovarian cancer is the most important cause of death in women The effect of cancer in Iran. Breast cancer is also one of the most common cancers in women, followed by cancer Cervix and ovarian and uterine cancers are also among the most common cancers in women. This issue is not only in Iran It...
Design and Analysis of Breast Cancer Detection System using Ultrasound Imaging and Deep Learning
, M.Sc. Thesis Sharif University of Technology ; Fakharzadeh, Mohammad (Supervisor) ; Kavehvash, Zahra (Co-Supervisor)
Abstract
One of the most important factors that make breast cancer such a dangerous and deadly disease is its hidden. One of the most important methods of revealing this disease is imaging. There are different types of imaging to reveal cancerous tissues (tumors), such as ultrasound, mammography, X-ray, etc. Ultrasound imaging is a cheap, convenient and accessible imaging. The aim of this project is to provide a breast cancer detection system that uses the images taken with this method according to the characteristics of ultrasonic imaging. Regarding cancer diagnosis, doctors identify the tumor with the help of their personal experience, which is based on the characteristics of the tumor image. In...
