Directional intraoperative probe

An intraoperative surgical probe comprising:

• a) a leading end comprising:
• I) a housing encompassing:
• A) a beta and gamma radiation permeable window;
• B) a visible light producing beta and gamma radiation detector comprising an array of radiation detector elements symmetrically arranged about a centrally located optical imaging light guide comprising a plurality of independent fiber optic conductors, each of said radiation detector elements independently connected to at least one separate photodetector via one of said independent fiber optic conductors;
• and
• b) a handle portion comprising:
• I) a housing encompassing:
• A) said separate photodetectors;
• B) a CCD camera;
• C) electronic circuitry;
• D) a proximity display or alert;
• and
• c) fiber optic conductors connecting said leading end and said handle such that visual information received by said optical imaging light guide in said leading end is transmitted to said CCD camera and visible light produced by said visible light producing radiation detector is transmitted to said photodetector producing an electronic output and said electronic output is interpreted by said electronic circuitry to provide directional information that is reported by said proximity display or alert.
