IEEE Symposium (IUS) Ultrasonics

作者： J.-U. Kluiwstra Y. Zhang P. VanBaren S.A. Strickberg E.S. Ebbini C.A. Cain Electrical Engineering and Computer Science Department And Bioengineering Program University of Michigan Ann Arbor MI USA

Catheter based ablation of cardiac tissue has been shown to provide an immediate and long lasting cure for cardiac arrhythmia. However, the procedure does not always allow placing the catheter in close proximity to the pathological tissues requiring ablation. Use of non-invasive focused ultrasound ablation in the moving heart is an attractive potential alternative to catheter based ablative therapy. In this paper, initial studies have been performed to explore the feasibility of using ultrasound phased array technology for this application. A 3-D treatment planning software package was developed to study the available acoustic windows allowing ultrasound to be focused on the myocardium. Numerical simulation studies of the feasibility of precise beam forming by propagating ultrasound around the ribs shows that the beam, even though formed by an irregularly shaped subset of phased array elements not blocked by ribs and air, was very sharply focused at the target. Using invasive phase aberration correction algorithms developed in the authors' lab, experiments with pork and human rib phantoms confirm the ability to precisely form beams with phased array through the available noncontiguous windows.

Frontiers in Education (FIE) Conference

作者： J.G. Harris B. Black Computer Engineering Program Cal Poly San Louis Obispo CA USA Electrical and Computer Engineering Rose Hulman Institute of Technology Terre Haute IN USA

Six computer assisted instruction modules are available on the Internet that provide tutorials and demonstrations for nonlinear circuit analysis and design. These modules introduce the student in a sequence to the concept of a nonlinear two terminal device (one port) and its analysis and of a nonlinear three terminal device (two port) and its analysis. In addition, through interactive, graphics driven animation, the user can be provided with experience in the design of circuits with these nonlinear devices. The specific devices presented to illustrate these concepts are the pn diode and the bipolar junction transistor; there are three modules available for each. These modules are available on the Internet, either by anonymous FTP or through the auspices of NEEDS, the National engineering Education Delivery System, being developed by the NSF SYNTHESIS engineering Education Coalition.

Conference on Advanced Research in VLSI

作者： A.G. Andreou K.A. Boahen Electrical and Computer Engineering Johns Hopkins University Baltimore MD USA Caltech CNS Program Pasadena CA USA

We present an experimental analog VLSI focal plane processor for the phototransduction, local gain control and edge enhancement of natural images. The single chip system incorporates 590,000 transistors in 48,000 pixels, and it has been fabricated on a 9.5/spl times/9.3 mm die in a 1.2 /spl mu/m n-well double metal, double poly, digital oriented CMOS technology. The organization of the system abstracts from the structure and function of the vertebrate distal retina. The adopted design style, current-mode subthreshold CMOS using circuits of minimal complexity offers the possibility of ultra low power dissipation and area efficiency, commensurate with VLSI integration.

IEEE Symposium (IUS) Ultrasonics

作者： O.S. Haddadin S.D. Lucas E.S. Ebbini Electrical Engineering and Computer Science University of Michigan Ann Arbor MI USA Bioengineering Program University of Michigan Ann Arbor MI USA

Presents a new distorted Born iterative algorithm for diffraction tomography which introduces kernel distortions only at carefully selected pixel locations. This algorithm attains the performance levels achieved by existing distorted Born iterative techniques, while maintaining the robustness of the Born iterative technique, especially in noisy situations. In addition, the algorithm has lower computational complexity and faster convergence rate when compared with existing distorted Born iterative algorithms. The authors present numerical simulations of the algorithm in noisy and noise-free environments. They also discuss an elementary experimental setup which is being used to validate their tomographic imaging algorithms.

IEEE Symposium (IUS) Ultrasonics

作者： Hong Wan P. VanBaren E. Ebbini C. Cain Bioengineering Program University of Michigan Ann Arbor MI USA Department of Electrical Engineering and Computer Science University of Michigan Ann Arbor MI USA

The possibility of using phased array generated multiple-focus patterns to reduce the overall treatment time in ultrasound surgery while restraining prefocal heating was investigated by simulating the performance of different possible schemes, i.e., single-focus scans, multiple-focus scans, and simultaneous multiple focusing without scanning, when used to "ablate" a 10/spl times/10/spl times/10 mm/sup 3/ volume 100 mm deep. In all cases, forty-one foci were used to cover the treatment volume. Multiple-focus scans were arranged into nine groups which were scanned in a raster fashion, as with single-focus scans. Keeping the treatment time constant, the maximum intensities, maximum thermal doses, dose distributions and prefocal heating zones for the different schemes were compared. It was found that the non-scanned simultaneous multiple-focus case required the smallest maximum intensity and dose, and resulted in the most even dose distribution. Single-focus raster scanning of individual lesions, as currently used with fixed-focus transducer, gave the worst results. These results show that multiple-focus patterns help considerably in reducing the maximum intensity and dose, and in generating a more even dose distribution assuming the same treatment time and prefocal heating. Alternatively they can be used to significantly reduce treatment time while keeping the maximum intensity and prefocal heating below predetermined limits.

2D large aperture ultrasound phased arrays for hyperthermia cancer therapy: design, fabrication and experimental results

IEEE Symposium (IUS) Ultrasonics

作者： P. VanBaren J.-U. Kluiwstra R. Seip Y. Zhang E.S. Ebbini C.A. Cain Electrical Engineering and Computer Science Department University of Michigan Ann Arbor MI USA Bioengineering Program University of Michigan Ann Arbor MI USA

Ultrasound has proven to be an effective modality for inducing hyperthermia for cancer therapy because of the spatial control of the SAR that may be achieved. The use of phased-array ultrasound applicators provides additional benefits because the ultrasound field may be changed rapidly (at electronic speeds) and may be used to focus the field at several locations simultaneously. To obtain these qualities, large apertures with element counts exceeding several hundred are needed. However, with the increase in the number of elements, both the control and fabrication process involve greater complexity. Therefore the construction of phased array systems, especially those using geometric focusing to increase intensity gain, has proven technically difficult. In order to avoid complex machining and mounting procedures, a modular approach to array construction has been developed. To test this approach, phased arrays with 192 and 512 elements have been designed, fabricated and characterized in the authors' laboratory. These arrays are composed of flat panels arranged to approximate a spherically shaped aperture. Experimental acoustic measurements for both arrays are presented and compared with computer simulations, showing good agreement. In addition, experimental results using these arrays, in conjunction with a control algorithm developed in the authors' lab, to induce and maintain hyperthermia in in vivo canine thigh muscle are presented. These results demonstrate the flexibility of such applicators, and the control which they can achieve over the SAR field.

Presents two methods for determining significant frequencies in surface EMG recordings. In the first method, time-frequency distributions (TFDs) are analyzed to determine the ten most powerful frequencies (over time). The TFD frequencies are further analyzed using a "cyclostationary" approach. In the second method, AR modeling is used to evaluate how significant spectral components in the surface EMG signals change over time. These methods are important for identifying significant spectral components in multichannel surface EMG recording so that these excitations can be localized within the muscle.

IEEE International Conference on Systems, Man and Cybernetics

作者： R.M. Voyles J.D. Morrow P.K. Khosla Robotics Ph.D. Program Carnegie Mellon University Pittsburgh PA USA Department of Electrical and Computer Engineering Carnegie Mellon University Pittsburgh PA USA

This paper explores shape from motion decomposition as a learning tool for autonomous agents. Shape from motion is a process through which an agent learns the "shape" of some interaction with the world by imparting motion through some subspace of the world. The technique applies singular value decomposition to observations of the motion to extract the eigenvectors. The authors show how shape from motion applied to a fingertip force sensor "learns" a more precise calibration matrix with less effort than traditional least squares approaches. The authors also demonstrate primordial learning on a primitive "infant" mobile robot.

Integrating sensors into robot systems is an important step towards increasing the flexibility of robotic manufacturing systems. Current sensor integration is largely task-specific which hinders flexibility. The authors are developing a sensorimotor command layer that encapsulates useful combinations of sensing and action which can be applied to many tasks within a domain. The sensorimotor commands provide a higher-level in which to terminate task strategy plans, which eases the development of sensor-driven robot programs. This paper reports on the development of both force and vision driven commands which are successfully applied to two different connector insertion experiments.
