Fast computation of optimized electrode arrays for 2D resistivity surveys
Four different methods to automatically select an optimal set of array configurations that gives the maximum resolution of the subsurface with a limited number of measurements for 2D electrical imaging surveys were tested. The first method (CR method) directly calculates the change in the model resolution for each new array added to the base data set, and uses this to select array configuration...
متن کاملSize-optimized 32-channel brain arrays for 3 T pediatric imaging.
Size-optimized 32-channel receive array coils were developed for five age groups, neonates, 6 months old, 1 year old, 4 years old, and 7 years old, and evaluated for pediatric brain imaging. The array consisted of overlapping circular surface coils laid out on a close-fitting coil-former. The two-section coil former design was obtained from surface contours of aligned three-dimensional MRI scan...

متن کاملSparse 2 D Arrays for Real - Time 3 D Ultrasound
Existing 3D ultrasound systems are based on mechanically moving 1D arrays for data collection and post-processing of data to achieve 3D images. To be able to both collect and process 3D data in real-time, a scaling of the ultrasound system from 1D to 2D arrays is necessary. A typical 2D-system uses 1D arrays with about 100 receive and transmit channels. Scaling of this system to get a 3Dsystem ...
متن کاملSparse Arrays for Real - Time 3 D Imaging , Simulated and Experimental Results
Abstract – This work presents the outputs from a project which aimed to lay the foundation of a 3D ultrasound imaging system where the emphasis was on real-time data acquisition and near real-time data visualization. To be able more precisely to describe the behavior of a sparse array system, a 25 Gbyte dataset containing every transmit and receive combination of a 50× 50-element fully connecte...
