1. one kind is used for determining imaging plane (18) with respect to the system (10) of the position of conduit, and described system (10) comprising:

  • The first conduit (12), it has ultra sonic imaging transducer array (16), and described ultra sonic imaging transducer array (16) is corresponding with described imaging plane (18);

    The second conduit (14), it has the first antenna (20), and described the second conduit (14) is different from described the first conduit (12) at least in part;

    AndProcessor (17), it determines that described imaging plane (18) is with respect to one angular coordinate information in described the first conduit (12), described the second conduit (14) and their combination, described angular coordinate information becomes with the first signal of described the first antenna (20)Wherein said the first conduit (12) comprises the second antenna (22) that arranges relatively with described ultra sonic imaging transducer array (16), and wherein said processor (17) be used for to be determined the described angular coordinate information of the described imaging plane (18) that the secondary signal with described the second antenna (22) becomes, and wherein said the second antenna (22) has the variable thickness that becomes with the angle around described the first conduit (12).
