Patient-specific catheter shaping for the minimally invasive closure of the left atrial appendage.

abstract：PURPOSE:Accurate needle tracking provides essential information for MRI-guided percutaneous interventions. Passive needle tracking using MR images is challenged by variations of the needle-induced signal void feature in different situations. This work aimed to develop an automatic needle tracking algorithm for MRI-guid...
