OFSETH: optical technologies embedded in smart medical textile for continuous monitoring of respiratory motions under magnetic resonance imaging

摘要: The potential impact of optical fiber sensors embedded into medical textiles for the continuous monitoring patient during Magnetic Resonance Imaging (MRI) is now proved. We report how two pure technologies can successfully sense textile elongation between, 0% and 3%, while maintaining stretching properties textile substrates a good comfort patient. Investigating influence different patients' morphology as well integration issues to let free all vitals organs for staff actions, OFSETH harness allows measurement respiration movements. For example, anaesthesia MRI examination uses same drugs any surgical procedure. Even if spontaneous respiration can be preserved most time, spontaneous constantly at risk being impaired by anaesthetic or by upper airway obstruction. Monitoring breathing activity needed assess adequate ventilation detect specific obstruction patterns. Moreover artefacts due physiological motions induce blooming effect on result. use synchronisation devices reducing these effects. Positioned certain strategic places according investigated organ, the presented could constitute an efficient adapted solution respiratory synchronisation MRI acquisition.
