History of Ultrasound of Physics and the Properties of the Transducer
Physics – History of Ultrasound Physics and Properties of Transducer
Ultrasound Physics developed from discoveries made by many professions from numerous countries over several centuries. At first, the discoveries were not related to medicine and were made by scientists in several other fields. However, as these discoveries were gradually combined, health care professionals began to see the usefulness of ultrasound physics for detection, diagnosis and treatment of many ailments. One constant in the history of ultrasound physics is the transducer, which converts energy to an image, and is still used in various forms, depending on the depth of the object to be imaged. The continued refinement of transducers and of Ultrasound Physics in general shows how valuable Ultrasound Physics is to the medical profession and to humanity. Though Ultrasound Physics will continue to develop, the current state of the art is so well-developed that ultrasound can now be accomplished in remote locations in real time with iPhones.
