Method of producing personalized RF coil array for MR imaging guided interventions

摘要

A method of manufacturing a personalized radio frequency (RF) coil array for magnetic resonance (MR) imaging guided interventions includes: acquiring diagnostic image data reflecting the anatomy of a portion of a patient's body; planning an intervention on the basis of the diagnostic image data, wherein a field of the intervention within the patient's body portion is determined; and arranging one or more RF coils on a substrate which is adapted to the patient's anatomy, in such a manner that the signal-to-noise ratio of MR signal acquisition via the one or more RF coils from the field of the intervention is optimized.

1. A method of producing a personalized array of one or more radio frequency (RF) coils for a magnetic resonance (MR) imaging guided surgical procedure on a portion of a patient's body, the method comprising:
creating a model of anatomy of the portion of a patient's body using acquired image data from at least one of X-ray, computed tomography (CT), and MR diagnostic images of the portion of a patient's body; determining, based on the acquired image data, an interventional area within the portion of the patient's body and an access path to the interventional area, the access path limiting access strategies during the surgical procedure; and providing an arrangement of a substrate by disposing the array of one or more RF coils on the substrate wherein; sizes, shapes and positions of the one or more RF coils are computed based on the acquired image data for optimal signal-to-noise ratio of an MR signal acquired from the determined access path and the interventional area, and; a shape of the substrate is adapted to a shape of the portion of the patient's body based on the acquired image data so as to position the array of RF coils firmly in close proximity on the portion of the patient's body during the surgical procedure.
