3-D measurement of body tissues based on ultrasound images with 3-D spatial information.
In this study, we developed a new method to perform 3-D measurements between the recorded B-scans using the corresponding spatial location and orientation of each B-scan, without the need to create a 3-D volume. A portable ultrasound (US) scanner and an electromagnetic spatial locator attached to the US probe were used. During data collection, the US probe was moved over the region-of-interest....
متن کاملSpatial Compounding of 3-D Ultrasound Images
One of the most promising applications of 3-D ultrasound lies in the visualisation and volume estimation of internal 3-D structures. Unfortunately, the quality of the ultrasound data can be severely degraded by artifacts, especially speckle, making automatic analysis of the 3-D data sets very di cult. In this paper we investigate the use of 3-D spatial compounding to reduce speckle. We develop ...
متن کاملAutomatic Registration of 3-D Ultrasound Images
One of the most promising applications of 3-D ultrasound (US) lies in the visualisation and volume estimation of internal 3-D structures. Unfortunately, artifacts and speckle make automatic analysis of the 3-D data sets difficult. In this study, we investigated the use of 3-D spatial compounding to improve data quality, and found that precise registration is the key. A correlation-based registr...
متن کاملCompensation of log-compressed images for 3-D ultrasound.
In this study, a Bayesian approach was used for 3-D reconstruction in the presence of multiplicative noise and nonlinear compression of the ultrasound (US) data. Ultrasound images are often considered as being corrupted by multiplicative noise (speckle). Several statistical models have been developed to represent the US data. However, commercial US equipment performs a nonlinear image compressi...
متن کامل3-D Compounding of B-Scan Ultrasound Images
Two applications of volume registration in 3-D ultrasound imaging, extended volume imaging (EVI) and 3-D Spatial compounding, are demonstrated both in phantom and clinical scans. Extended volumes were composed by obtaining partly overlapping scans, registering the overlapping volumes, and displaying the complete set of volumes in their relative spatial orientations as determined by the registra...
