Ultrasound Transducers Melissa Genovese, MED, RDMS, RVT, RT(R)1 Abstract Diagnostic medical ultrasound transducers have evolved through the years and have contributed significantly to improved patient care. These types of transducers are used in direct contact with the test material and therefore require a highly durable wearplate. The transducer is inserted into a man's rectum to view the prostate. These guidelines specifically address the use, handling, cleaning, disinfection or sterilization, transport, and storage of transducers (hereinafter referred 0000000016 00000 n It is the hand-held part of the ultrasound machine that is responsible for the production and detection of ultrasound waves. 0000001276 00000 n 0000006921 00000 n 1915 – Paul Langevin, invented a hydrophone, which was referred to as the “first transducer” From 1949 to 1951, Joseph Holmes and Douglas Howry pioneered the invention of B-mode ultrasound equipment. 0000003500 00000 n Philips ultrasound transducers are handheld and ergonomic, easily adapting to your practice. 0000004362 00000 n Ultrasound transducer doppler ppt pdf pk 1.
