Stan Lapidus's first company, Itran Corp., uses imaging technology for industrial quality control. His new company will use imaging to check Pap smears. Seems all 50 million cervical-cancer tests done in the United States each year are inspected individually by people viewing scores of slides a day. Lapidus's Cytyc Corp., in Marlborough, Mass., is developing a machine that can identify cultures with abnormal cells. Expected benefits: a 30% to 50% decline in Pap-smear costs and a 500% increase in lab workers' productivity.
