Effects of Non-Elevation-Focalized Linear Array Transducer on Ultrasound Plane-Wave Imaging

Effects of Non-Elevation-Focalized Linear Array Transducer on Ultrasound Plane-Wave Imaging

Plane-wave ultrasound imaging (PWUS) has become an important method of ultrasound imaging in recent years as its frame rate has exceeded 10,000 frames per second, allowing ultrasound to be used for two-dimensional shear wave detection and functional brain imaging. However, compared to the traditional focusing and scanning method, PWUS images always suffer from a degradation of lateral resolutio...

1.5-d Ultrasound Transducer Array Charlacterization

The objective of this work was twofold. The first was to investigate theoretically and cxperimentally the acoustical and electrical parameters of 1.5-D ultrasound transducer arrays for 3-D imaging applications. Modeling and simulations of arrays of various geomctry, center frequencies, and materials were performed, analyzed and optimized. The optimization criteria was the best achievable latera...

Quantitative, Free-Hand 3D Ultrasound Imaging based on a Modified 1D Transducer Array

An approach for acquiring dimensionally accurate 3D ultrasound data, based on a modified 1D transducer array, is presented. The method avoids many of the drawbacks of conventional approaches to 3D ultrasound data acquisition. Scanning is simple and easy to perform in a clinical setting. A modified 1D transducer array is employed comprising a central conventional 1D ‘Imaging’ array and two perpe...
