Selection of Effective Features from Raw US RF Signals to Enhance Intelligent Breast Lesion Classification Using Machine Learning

Mahsa Arab; Ali Fallah; Saeid Rashidi; Maryam Mehdizadeh Dastjerdi; Nasrin Ahmadinejad

Volume 17, Issue 2 , September 2023, , Pages 140-150

  Breast cancer stands as the most prevalent form of cancer among women, with over 80% of early-stage breast abnormalities being benign. Timely detection is therefore crucial for prompt intervention. Ultrasound Radio Frequency (US RF) signals represent a non-invasive, and real-time screening method for ...  Read More

Comparison of the Cervical Multifidus Muscle Dimansions Change During the Shoulder Joint Activities using of Predictive Models

Sharare Kian-Bostanabad; Mahmoud Reza Azghani; Leila Rahnama

Volume 9, Issue 4 , February 2015, , Pages 341-350

  The cervical multifidus muscle is known as one of the deep neck extensor muscles that its dysfunction have been reported in people with neck pain.With regard to the limits on the evaluation of this muscle activity using electromyography, ultrasound was used to find out its function recently. The aim ...  Read More

Domestic Construction of Soft Tissue Phantom for Validation Linear Quasi –Static Elastography

Zahra Saghaei Noosh Abadi; Atefe Aghajani; Mohammad Haghpanahi

Volume 7, Issue 1 , June 2013, , Pages 1-11

  We introduce how we may produce an experimental phantom for modeling the mechanical properties of soft tissue. Gelatin materials are used to construct the phantom. Our phantom comprises of two different types of tissue; tumor and background normal tissue. Weight ratio of the dry gelatin and deionized ...  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

Design And Prototyping Of An Ultrasonic Pulsed Doppler System For Blood Velocity Measurement In Vessels

Nima Hemati; Mohammad Javad Abolhassani

Volume -2, Issue 1 , July 2005, , Pages 35-46

  Nowadays, various methods have been suggested to measure and monitor blood velocity variation in arteries and veins. Ultrasonic velocimetry is one of these methods, which is based on Doppler shift frequency measurement and the blood flow velocity calculation using Doppler shift signal. Using velocity-time ...  Read More

Optimal Design Of Beam Pattern Of Ultrasound Arrays Considering Sensitivity Of Transducer

Seyed Mahmoud Sakhaei; Ali Mahloojifar

Volume -2, Issue 1 , July 2005, , Pages 47-56

  The beam pattern profile of an ultrasound array is of great importance in ultrasound imaging. This profile could be enhanced by weighting the elements of array. However, this technique will decreases the signal to noise ratio (S/N) and consequently the quality of the obtained image. In this study, the ...  Read More
