The LPI Model 121 Laser Positioner is used by physicians to assist in needle positioning during breast biopsies.  By carefully and precicely accounting for the parallax effect of the source of the X-Ray beam, the doctor can sample even small tumors on the first attempt.

This device can be fit to mount on all current analog and digital mammography X-Ray machines.

This device demonstrates LPI's mastery of complex gear arrangements and laser optics.
