| Abstract | In this live demonstration, a Tactile Imaging Sensor is presented, which is used for quantifying the mechanical properties of breast tumor. A tumor or malignancy feels different from the tissue surrounding it, which motivates the development of this system. Currently, a subjective method of clinical breast examination is performed for early detection of breast cancer. The method only provides qualitative information about the size and elastic modulus of suspicious lesion. To complement this method, we introduce a tactile imaging sensor that provides quantitative interpretations of the mechanical properties of embedded inclusion. In this sensor, a flexible Polydimethylsiloxane (PDMS) optical waveguide is used as the sensing probe. The sensing probe is illuminated by light emitting diodes in such a way that the total internal reflection occurs. When the embedded inclusion is compressed from the surface by the probe, the internally reflected light inside the probe is scattered. This scattered light is then captured by a near-infra-red CMOS camera, and forms the tactile images. Simultaneously, a load cell records the force reading. These images and force readings are then analyzed for estimating the size and elastic modulus of the embedded inclusion. This high resolution optical sensor offers a non-invasive and non-ionized technique for tumor screening. It is also a cost-effective and portable system, which requires minimal training of the operator. The demo will highlight the sensor use by estimating the mechanical properties of embedded inclusions inside a silicone phantom. |

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.
