Abstract
A stereo radiolocalization and targeting system (100) includes a table assembly (102) for supporting a patient (104), a stereo radiolocalization subsystem (117), a medical instrument support subsystem (119), and an ultrasound imaging subsystem (121). The stereo radiolocalization subsystem (117) 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 (119) allows for targeting of a medical instrument (118) to the area of interest for treatment, extraction or other procedures. The imaging subsystem (121) provides real-time imaging for use in penetration path selection and monitoring medical instrument insertion. Flexible positioning support mechanisms (120, 122, and 124) provide substantial positioning flexibility for various elements of the system (100).
