A four dimensional ultrasound is seen at a pregnancy clinic in Arlington, Texas November 26, 2007. The clinic offers free services to what it deems are "vulnerable women" considering an abortion. Part of a program called "Option Ultrasound," sponsored by the conservative advocacy group Focus on the Family, the clinic works on the principle that women who view images of their fetus are less likely to have an abortion.
