title: Benedict Cassen: the father of body organ imaging.
abstract: The invention of the radioisotope scanner by Benedict Cassen was seminal to the development of body organ imaging. Cassen assembled the first automated scanning system in 1950. It was a motor-driven scintillation detector coupled to a printer. The scanner was used to image the thyroid gland after the administration of radioiodine. Later, with the development of organ-specific radiopharmaceuticals the scanner was widely used during the late 50s until the early 70s to image the body organs.
