Electromagnetic tracking systems (EMTS) are used in surgical navigation to detect the position of a surgical instrument in the patient's anatomical 3D model. This study proposes the development and evaluation of a new EMTS able to provide a large tracking volume. The proposed system provides the position of a small sensor coil inserted into a surgical tool by measuring and elaborating the voltage signal generated by the coil. To characterize the measurement repeatability when the distance from the field generator changes, experimental tests by using an anthropomorphic robot and statistical studies of measurement data were performed. The results show a good measurement process with encouraging performance obtained with the proposed voltage-to-position conversion method.

Abstract
Electromagnetic tracking systems (EMTS) are used in surgical navigation to detect the position of a surgical instrument in the patient's anatomical 3D model. This study proposes the development and evaluation of a new EMTS able to provide a large tracking volume. The proposed system provides the position of a small sensor coil inserted into a surgical tool by measuring and elaborating the voltage signal generated by the coil. To characterize the measurement repeatability when the distance from the field generator changes, experimental tests by using an anthropomorphic robot and statistical studies of measurement data were performed. The results show a good measurement process with encouraging performance obtained with the proposed voltage-to-position conversion method.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
