| Abstract | In this paper, we present a method for simulating the field intensity of ultrasound beam using a two dimensional phased array transducer for High Intensity Focused Ultrasound (HIFU) based surgery. The parameters used and the field modeling is based on Huygen's principle. We further simulated the field intensity of ultrasound beam in two media, taking into consideration the effect of different attenuation coefficients and beam refraction at the interface. Simulation results show that a focused HIFU beam can be obtained by means of manipulating the phase of the signal in each of the elements in a generic ntimesn-element square array transducer. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
