Abstract: A laser imaging apparatus comprises a platform for supporting a female patient in front-down, prone position, including an opening permitting a breast of the patient to be vertically pendant below the surface of the platform; scanning mechanism including a multi-faceted mirror adjacent the underside of the platform, the mirror being rotated about its own axis and orbited around the pendent breast; a source of coherent near infrared narrow light pulses operably directed to the multi-faceted mirror; optical reflectors directing the light pulses onto the facets of the mirror from a point spaced from the platform for reflection in a series of horizontal fan shaped beams through a breast pendent below the platform; photodetectors operably disposed to detect the light pulses after passing through the breast; circuit for deriving voltages proportional to the intensity of the received pulses; and computer programmed for storing and displaying images of tissue in the breast derived from the voltages.
