Modeling of 2d Array Transducer for Beam Optimization in 3d Ultrasound Imaging
Ultrasound imaging has become an effective imaging system in medicine. The ultrasound images are generally created in two-dimensional format; however three dimensional images offer better observation and interpretation. To create three-dimensional images, special transducers with two dimensional arrays should be used. These transducers consist of piezoelectric elements arranged in two dimension...
متن کامل2D Transducer Array for High-Speed 3D Imaging System
3D imaging system was developed utilizing a combination of sparse 2D arrays, the synthetic aperture focusing technique, and coded excitation of a solution for high-speed 3D ultrasound imaging, since it could formulate multiple transmitting beams as well as receiving beams with a minimum number of transmissions. A 40 × 40 array of PZT elements was fabricated with a conventional dice-and-fill pro...
متن کاملQuantitative, 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...
متن کامل2D array design based on Fermat spiral for ultrasound imaging.
The main challenge faced by 3D ultrasonic imaging with 2D array transducers is the large number of elements required to achieve an acceptable level of quality in the images. Therefore, the optimisation of the array layout, in order to reduce the number of active elements in the aperture, has been a research topic in the last years. Nowadays, array technology has made viable the production of 2D...
متن کامل1.5-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...
