Registration of intra-operative Ultrasound to CT images using Two-stage point based registration algorithm for Correction of Deformation in liver phantom

Fateme Nazem; Alireza Ahmadian; Mohammad Javad Abolhasani; Nasim Dadashi; Masoume Gity; Mohammad Bagher Shiran

Volume 5, Issue 4 , June 2011, , Pages 351-358

  Abstract: Image guided liver surgery based on intra-operative ultrasound images has received much attention in recent years. Using an efficient point-based registration method to improve both the accuracy and computational time for registration of pre-deformation CT liver images to post-deformation Ultrasound ...  Read More

Estimation of Transient Evoked Otoacoustic Emission Based on Reverse Middle Ear Transfer Function

Mohammad Javad Abolhassani; Yousef Salimpour; Parisa Rangraz

Volume 4, Issue 3 , June 2010, , Pages 249-256

  An otoacoustic emission is a low-level acoustic signal which is generated in cochlea. It could be recorded with a sensitive probe in the outer ear canal. OAEs are considered to be related to the amplification function of the cochlea. Outer hair cells are the elements that enhance cochlear sensitivity ...  Read More

Fast And Noninvasive Thermal Monitoring In Ultrasound Digital Images Using Optical Flow Method

Bahram Momen Mehrabani; Mohammad Javad Abolhassani; Alireza Ahmadian; Javad Alirezaie

Volume 3, Issue 1 , June 2009, , Pages 47-54

  The main purpose of this work is introducing a novel method of temperature monitoring using B-Mode Ultrasound digital images. Thermal dependence of sound speed causes a virtual displacement of scatterer particles. The virtual displacement is computed using speckle tracking methods. Horn-Shunck algorithm ...  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
