Abstract
A portable laser guided alignment apparatus includes a laser line beam source and a laser fan beam source, with the line beam being in the same plane as the fan beam. The apparatus further includes mechanisms for adjusting the angle of the fan beam relative to a vertical reference plane and for adjusting the angle of the line beam within the plane of the fan beam. Additionally, measurement devices are included to measure the angle of the fan beam relative to the vertical reference plane, and to measure the angle of the line beam relative to a vertical reference line within the fan beam plane. The apparatus provides precise alignment for biopsy tools and other instruments used in standard biopsies, discolysis, stereotaxis, and other medical procedures wherein highly accurate positioning and insertion of instruments into a patient are required.
