An ultrasound is the cyclic sound pressure that is greater than human hearing. Although we can’t hear an ultrasound, it does have a measurable effect on the human mind. It is also used in diagnostics. The medical sonography or ultrasonography is an ultrasound-based diagnostic medical imaging technique. This technique is used to create images and visualize different parts of the body using real time tomographic images. Tendons, many internal organs, muscles, pathological lesions, and a fetus can all be viewed by medical ultrasound equipment. Obstetric sonography is when the equipment used during pregnancy to view the fetus.
This equipment helps perform diagnosis or therapeutic procedures. Medical ultrasound equipment is highly effective for imaging the soft tissues of the body. To produce a better image of superficial structures, these structures are imaged at a higher frequency. Some of these superficial structures include muscles, testes, breast, tendons, and the neonatal brain. A special diagnostic ultrasound system is ideal for biopsies or drainage of fluid collections.
A sonographer is the medical professional that performs the specialized scan for diagnostic purposes. Using a diagnostic ultrasound system, the sonographer can perform an effective procedure. The sonographer uses a transducer, which is a hand-held probe. The transducer is placed directly on and moved over the patient. To couple the ultrasound, a water-based gel is used between the had-held probe and the patient.
