PERSONALIZED RF COIL ARRAY FOR MR IMAGING GUIDED INTERVENTIONS

摘要

The invention relates to a method of manufacturing a personalized RF coil array for MR imaging guided interventions. The method comprises the steps of: —acquiring diagnostic image data reflecting the anatomy of a portion of a patient's body (10); —planning an intervention on the basis of the diagnostic image data, wherein a field of the intervention within the patient's body (10) portion is determined; —arranging one or more RF antennae (11, 12, 13) on a substrate (19), 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 antennae (11, 12, 13) from the field of the intervention is optimized. Moreover, the invention relates to a computer program and to a computer workstation.

1. A method of producing a personalized RF coil array for MR imaging guided surgical procedure on a portion of a patient's body, the method comprising the steps of:
creating a model of anatomy of the portion of a patient's body using image data from at least one of X-ray, CT, and MR diagnostic images; determining 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 arranging a substrate including the RF coil array having one or more RF antennae on the model of the determined interventional area, wherein sizes, shapes and positions of the RF antennae are computed based on the image data for optimal signal-to-noise ratio of an MR signal acquired from the access path and the interventional area, and wherein a shape of the substrate is adapted to a shape of the model so as to position the RF coil array firmly in close proximity on the portion of the patient's body during the surgical procedure.
