Karl DussikBorn 9 Jan 1908; died 19 Mar 1968 at age 60.Karl (Theodore) Dussik was an Austrian neurologist and psychiatrist who has been called the "Father of Ultrasonic Diagnosis". In 1942, he published the first transmission ultrasound investigation of the brain Hyperphonography of the Brain, which he used to image a cerebral ventrical. He placing a patient's head between an ultrasound emitter and a receiver. In this way, he tried to visualize the cerebral ventricles by measuring the ultrasound beam modification through the head. However, the bone of the skull absorbed much of the ultrasound energy, and the image created by different bone thickness obscured any reliable image of the brain alone. However, his work with transmitted ultrasound stimulated the use of reflection techniques.« |
