Physics -- History of Ultrasound Physics and Properties of Transducer
The history of Ultrasound Physics has involved contributions from many professions from a number of countries over hundreds of years. The first developments, dating as far back as 1794, were made by scientists outside the medical profession and were often disconnected from each other. As science progressed and scientists combined these discoveries, the medical profession gradually realized the value of ultrasound for detection, diagnosis and treatment. From the first uses of ultrasound physics with large, clumsy and limited equipment, ultrasound has been so refined that ultrasound can now be accomplished with easily portable equipment at the site of care, far from any hospital or laboratory.
A vital part of these ultrasound developments that is still used today is the transducer, a device that efficiently converts electrical energy into images. Consisting of a sensor and the associated circuitry, the type of transducer used in modern medicine depends on the depth of the object to be imaged. High frequency transducers give clearer images but do not penetrate as deeply while lower frequency transducers penetrate more deeply but give images that are less clear. No matter which type of transducer is used, modern transducers are commonly made of either piezoelectric or multi-element arrays.
Introduction
Ultrasound Physics developed over hundreds of years from the contributions of many individuals from different countries over hundreds of years. Though the first developments were made by scientists outside the medical profession, as those developments came together, the medical profession gradually realized that ultrasound could be effectively used to detect, diagnose and treat a number of human illnesses. The value of ultrasound physics for humanity can be seen in its continual refinement, including the continual refinement and use of the transducer. This technology has become so refined that ultrasound can now be quickly used with portable equipment at the point of care in remote locations.
