Abstract
A sense head comprises a plurality of coils and a needle window. The sense head is operable to receive RF signals communicated from a needle target such as an injection port located within a patient. A user interface is configured to visually display an indication to a user relating to the positioning and orientation of the sense head relative to the needle target. The positioning and orientation may be determined based on RF signals received by the coils in the sense head. With the sense head positioned based on information provided through the visual display, the user may insert a needle through the needle window to reach the needle target. The sense head may also receive communications relating to the pressure of fluid in an implanted device. The user interface may further display information relating to the fluid pressure in the implanted device.
