A portable ultrasound is smaller and lighter than the usual diagnostic machines used in hospitals. The first portable ultrasound arrived in 1980, but the battery powered ones arrived in late 1990s. Portable ultrasound device is very easy to use and can be carried at the time of emergency to remote places.
Ultrasound machines use the same technique of sonar which was developed for ships at the sea. The process begins with a machine called a transducer. This machine, when placed over the belly, emits sound and the sound that bounce back is analyzed by a computer within the machine and is then transformed into moving images. Portable ultrasound machines give people the ability to see images of their unborn child while in the comfort of their own home. Because of this device, fewer babies are being lost during the course of pregnancy not only in the United States but all over the world. Results of an ultrasound imaging study may be discussed with the patient immediately, or the patient may be called back at a later date by the doctor to discuss the results.
In addition to being used for diagnostic purposes, ultrasound is also used in some medical procedures such as amniocentesis to guide the doctor while he or she works. One huge advantage of ultrasound beyond its relative safety is its ability to reflect real-time activity in the body. Using ultrasound, a doctor can see how the structures of the body move, a big improvement over static medical imaging such as x-rays, which only captures a single image at a given moment. High frequency sound waves are sent through an area of the body, where they are reflected and sent back to the ultrasound device. The result is an accurate depiction of organs, muscles, and joints.
When it comes to buying portable machines, do not compromise with the quality & performance of the device and always prefer branded portable ultrasound equipment. Online portals offer a variety of medical equipment at discounted rates and also provide free shipping on the systems.
