Advantages and limitations of the various magnetic manipulation methods of untethered agents in the human body

摘要: Magnetic manipulation of untethered agents is likely to play a critical role in several interventions conducted the human body. Such ranging from surgeries drug deliveries require magnetic methods with characteristics that are best suited for type being considered. The main include but not limited field strength, magnitude gradients, rate at which such directional gradients can vary, degree-of-freedom (DOF) supported, appropriateness imaging modality real-time positional assessments manipulated, total workspace, and duty cycle or period time be performed without interruption. Since no single existing method optimized all above characteristics, emphasizes need select appropriate will offer required given interventions. Here, study review systems corresponding related preferred provided.
