One of the most common methods used in medical imaging is ultrasound. This form of medical imaging is considered to be the safest and also has a variety of applications in that field. Also, most patients prefer ultrasound over other medical imaging methods because it has no harmful effects which may cause health complications in the future. This form of medical imaging has also been made available in most of the clinics and so a significant number of patients can access the services. Unlike methods such as ionizing radiation, ultrasound makes use of sound waves for it to function and provide the results that are expected. Before choosing ultrasound every patient should take their time to understand in detail how that method works so that they can make informed decisions. To provide images of body structures using ultrasound high-frequency waves are transmitted from the probe through a conducting gel to the patient’s body. Once these waves have penetrated the body of the patient they bounce back after hitting the targeted structures of the body and that is what is used in creating the required images. There is also another form of ultrasound that is referred to as Doppler.
You need to know that this form of ultrasound is unique because it does not use the sound waves which are transmitted into the body structures. It uses sound waves which provide an opportunity to see blood as it flows through the body veins and arteries. Another form of medical imaging is X-ray imaging. Note that X-ray imaging is considered to be one of the oldest methods of medical imaging and also the most frequently used methods. Research has shown that most of the people have at least had a single X-ray in the course of their lives. X-ray works with the use of wavelength and frequency which human beings cannot manage to see with their naked eyes. To create a picture of what is going on in the human body this X- rays are penetrated in the body through the skin.
