Abstract
A guidance system for guiding insertion of a needle into a body of a patient utilizes ultrasound imaging or other suitable imaging technology. The guidance system can include an imaging device including a probe for producing an image of the internal body portion target, such as a blood vessel. The imaging device can be configured to provide at least one indication of status via sensory feedback based on a determined position of the needle, for example via a plurality of light-emitting diodes located on the device. One or more sensors can be included with the probe that can sense a magnetic field associated with the needle. The system may include a processor that can receive magnetic field data sensed by the at-least-one sensor to determine the position of the needle. The system can also include a display that depicts the determined position of the needle.
