Title

Effects of Beamforming Techniques on Quality of Ultrasound Computed Tomography Images

Pages

  349-358

Abstract

 Background: In body tissues, tumors generally have different speeds of sound (SOS) than normal tissues. In this respect, Tomography/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">ultrasound computed tomography (UCT) can generate a cross-sectional SOS map as an innovative ultrasound imaging method. This technique can produce images with a resolution of millimeters and a high signal-to-noise ratio. Objective: This study aimed to improve UCT image quality without increasing breast cancer screening and diagnosis time. Material and Methods: In this analytical study, a ring-shaped UCT breast imaging system was simulated using the K-wave toolbox of MATLAB. The system has a 20 cm diameter and 256 ultrasonic piezoelectrics placed in the ring’, s circumference. Different beamforming techniques imaged two designed phantoms (i. e., resolution and contrast), and the resolution and contrast to noise ratio (CNR) were calculated. Results: The results of resolution phantom imaging without any beamforming showed that only bars with the value of 0. 125 and 0. 167 lp/mm were distinguishable, and the 0. 1 bars were not recognizable in the imaging. In addition, increasing the number of transmitters led to no noticeable change in resolution for 0. 125 and 0. 167 lp/mm bars. In all beamforming techniques for imaging the contrast phantom, the CNR parameter up to an object with a diameter of 8 mm increases with increasing diameter without any change. Conclusion: The beamforming technique using three simultaneous transmitters improved the resolution by about 1 mm compared to the normal strategy. In addition to highcontrast images, beamforming with 9 simultaneous transmitters led to a preferable technique.
