| Summary: | The present invention relates in general to medical instrument guidance for minimally invasive medical procedures and, in particular, to three-dimensional guidance using stereo radiolocation and related imaging for penetration path selection. The present invention has particular advantages with respect to sentinel node biopsy procedures.
A stereo radiolocalization and targeting system () includes a table assembly () for supporting a patient (), a stereo radiolocalization subsystem (), a medical instrument support subsystem (), and an ultrasound imaging subsystem (). The stereo radiolocalization subsystem () provides three-dimensional localization information for an area of interest within the patient's body such as a sentinel node. The medical instrument support subsystem () allows for targeting of a medical instrument () to the area of interest for treatment, extraction or other procedures. The imaging subsystem () provides real-time imaging for use in penetration path selection and monitoring medical instrument insertion. Flexible positioning support mechanisms (and ) provide substantial positioning flexibility for various elements of the system (). |
