1. A medical positioning system comprising:
- a probe adapted for insertion into a patient, the probe having one of a transmitter and a receiver provided thereon, the transmitter being adapted for generating a signal and the receiver being adapted to detect the signal;
a plurality of nodes provided on a flexible framework and arranged to substantially surround at least a portion of the patient, the nodes having the other of the transmitter and receiver provided thereon; and
a controller electronically connected to the receiver and adapted to interpret the signals received by the transmitter;
whereby the position of the probe with respect to the plurality of nodes can be determined by interpreting the signals controller.

Abstract
A method and apparatus for positioning a probe inside a patient including a plurality of transmitter/receiver nodes arranged around the patient for communicating with the probe and generating navigation signals, a system for generating one or more positional signals in response to the navigational signals, and a system for collecting and analyzing those positional signals to determine the location of the medical instrument inside the patient'"'"'s body. The transmitting/receiving nodes may be arranged on a flexible blanket which is wrapped around and adhered to the patient'"'"'s body or over a table supporting the patient'"'"'s body.
