| Abstract | The purpose of our study is a measurement of 3D (three dimensional) distance between an artificial cement-type cup and a artificial femoral head in a living patient's body after THR(total hip replacement) from an AP(anterior-posterior) Roentgen image and a lateral image, when the angle between the two images is unknown. Recently we proposed a measurement method for non-cement-type cup. We modified the 3D measurement method for a non-cement cup with evolutionary computation(EC) and extend the framework for a cement-type cup. Our method needs only two times of shots using an ordinary Roentgen equipment without measurement the angle of the two images. So our method is superior to Martell's Method. And it needs no metal balls in a patient body unlike RSA (Roentgen stereophotogrammetric analysis). We show the result of a computer simulation with CG (computer graphics) image we made and the result in vitro with Roentgen images of artificial cup and head moved by a micro-manipulator. |

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.
