Susceptometers for foreign body detection

摘要: Methods and apparatus for minimizing the effects of temperature drift in a magnetic susceptibility measurement instrument, such as an instrument used pre-MRI screening presence ferromagnetic foreign bodies. The field source sensors can be combined into single, rigid unit. stability sensitivity required high quality measurements achieved through symmetrical design source-sensor unit, minimization thermal stresses, variations, use materials with low expansion coefficients, or appropriate combinations thereof. Use patient eye movement where is being screened, water bag between telemedicine to facilitate performance necessary computations also incorporated.
