Abstract:
Magnetic Induction Tomography (MIT) is an imaging technique for passive electrical properties used in industrial and biological imaging. In the case of biological purposes, high resolution measures of the magnetic field induced in the body and the ability to acquire data at several points along its border are two major challenges of MIT. In a previous work we have developed a prototype that allows precisely moving sensing and source coils, improving data quality and quantity for the tomographical image processing. Several alternatives for stability and resolution improvements have been presented. However, all of them had limitations in terms of stability and resolution for a moving coils system. This paper presents a new geometric setup built for a moving sensing coils prototype that allows the cancelation of the carrier field independently of the acquiring position.
