Nature of Medical Technology

  • Science deals with natural world and the interralationship among the biological, psychological, social world

  • Technology - application of science in ways beneficial to society

    • physical artifact, machine, intrument

  • Medical Technology - designed to improve the detection, diagnosis, treatment, monitoring of disease

  • Clinical Laboratory Technologist: examination and analysis of body fluids, tissues, cells

  • with the increasing automation, the work of medtech becomes less hands-on and more analytical
