An increasing number of minimally-invasive percutaneous needle interventions is performed under MR guidance including biopsies, targeted drug delivery and thermal ablations. All of these procedures require the identification of a skin entry site for needle placement. Even though this sounds straightforward, it is often a time consuming process as the entry site is usually identified in an iterative fashion under real-time imaging using a fingertip or water-filled syringe. The method presented allows to rapidly, accurately, and reproducibly localize the skin entry site without the need for any additional imaging or hardware.
