By the help of technological advances such as the development of computer and imaging technologies, surgical navigation has started to be used rapidly in medical literature. It is one of the recent methods used to track surgical tools inside the operation volume. In light of vital advantages as operation safety, minimally invasive application compatibility, reduction of operation times and reduced post operation complication risks, surgical navigation has been rapidly adopted throughout the relevant fields. Considering these, this study both tries to apply an introduced analytical method to one of the most important steps of surgical navigation as registration and compares the results within the scope of application compatibility. Throughout the study, a solid model with known dimensions was placed inside a capture volume in which the motion cameras are able to provide position measurements. Carrying out point based registration method by taking necessary measurements, relation between the model reference and measurement space reference was calculated by means of a transformation matrix. Using acquired relationship, measured landmark positions of the model were compared with the structurally known real landmark positions. At the end of the study results were given and the applicability of the introduced analytical solution method in point based registration is discussed. |
