Patent ID: 8249693

Claim:
A gamma guided stereotactic localization system comprising: a gamma camera; a cassette mounted on top of said gamma camera; a sliding slant-hole collimator arrangement including a set of oppositely viewing slant-hole collimators coplanar to each other and adapted to slide within said cassette, each of said collimators having parallel slant holes therein; said set of slant-hole collimators slideable within said cassette; a grid localization plate mounted above said cassette and adjustable in distance with respect to said cassette, said grid localization plate including grid openings therein; a biopsy needle guide including a biopsy needle positioned above said grid localization plate; a gamma emitting fiducial source in said grid localization plate; and a gamma emitting marker source in said biopsy needle; wherein each of said collimators is slideable and repositionable within said cassette thereby creating opposite viewing angles and stereo images from said gamma camera and enabling determination of the three dimensional location of a region of interest.
