About Sound Medical Imaging New Conway Business Offers A Sound Choice In Medical Imaging Mark Cartier does 3-D and even 4-D ultrasounds at his business, Sound Medical Imaging, in Conway, New Hampshire. In pregnancy evaluations, a live 3-D ultrasound provides a clearer image of the baby inside the womb. "4-D", Cartier explains, "takes the 3-D image and adds motion." Together, these images can be transferred to videotape or CD and given to patients as keepsakes of their diagnostic exams.
