Abstract | A new Pigeon Hole Imaging (PHI) method was conceived based on the 4-electrode Focused Impedance Method (FIM) developed by members of our group earlier. The FIM uses a group of 4 electrodes placed at the corners of a square region giving an enhanced sensitivity within the square, and the PHI uses many such groups arranged in a square or rectangular matrix in which the individual FIM values in the matrix elements form the pixel values of the image directly. The present work is the first approach to generate a graphical image for one or more objects within a prescribed area using the new PHI concept. Since the sensitivity outside the focused zone is not necessarily zero, though small, these may contribute to an erroneous image when a number of objects are present at close proximity. Some rules were developed to minimise such errors, and necessary software has been developed based on these rules to achieve an apparent higher image resolution. As a test for the software, simulated data were generated for assumed distributions of one or more objects within a specified area based on published experimental sensitivity values of 4-electrode FIM. PHI images were then produced using the developed software which gave a satisfactory rendition of the original object distribution. Although defined in 2D, both FIM and PHI may be useful in studying body organs using surface electrodes because of current flow in the $3^{rd}$ dimension, giving 3D sensitivity. In the study of the functions of different body organs that changes in size or position with time, PHI may be useful. |

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.
