A guidance system for assisting with the insertion of a needle into a patient body is disclosed. The guidance system utilizes ultrasound imaging or other suitable imaging technology. In one embodiment, the guidance system comprises an imaging device including a probe for producing an image of an internal body portion target, such as a vessel. One or more sensors are included with the probe. The sensors sense a detectable characteristic related to the needle, such as a magnetic field of a magnet included with the needle. The system includes a processor that uses data relating to the sensed characteristic to determine a 3-D position of the needle. The system includes a display for depicting the position of the needle. The needle can include a donut-shaped magnet disposed about the needle cannula, or a removable stylet with a magnetic element and a strain gauge for detection of the needle distal tip.
1. A guidance system for inserting a needle into a body of a patient in connection with imaging technology, the system comprising: an imaging device including a probe, the imaging device configured to produce an image of an internal body portion target;a stylet removably disposed within the needle,
1. A guidance system for inserting a needle into a body of a patient in connection with imaging technology, the system comprising: an imaging device including a probe, the imaging device configured to produce an image of an internal body portion target;a stylet removably disposed within the needle, the stylet including at least one magnetic element comprising a plurality of passive ferromagnets placed adjacent one another;at least one sensor included with the probe that senses a magnetic field of the at least one magnetic element of the stylet;a processor that uses data relating to the magnetic field sensed by the at least one sensor to determine a position of the needle in at least two spatial dimensions relative to the probe; anda display that depicts the determined position of the needle together with the image of the target. 2. The guidance system as defined in claim 1, wherein the at least one sensor is disposed on an exterior portion of the probe, and wherein the plurality of ferromagnets are disposed proximate a distal end of the stylet. 3. The guidance system as defined in claim 2, wherein the at least one sensor includes an annular sensor that is received about a head portion of the probe. 4. The guidance system as defined in claim 1, wherein the at least one sensor includes orthogonal sensing components so as to enable determination of a position of the at least one magnetic element of the needle in three spatial dimensions and a pitch and a yaw attitude of the at least one magnetic element. 5. The guidance system as defined in claim 1, further including a strain gauge on the stylet for detecting bending of the needle.
