Ultrasonic examination: a description of the procedure and the types
Medicine knows many ways of differentsurveys. This can be a routine examination, laboratory diagnosis, magnetic resonance imaging and ultrasound examination. The last method will be discussed in this article. You will find out what kinds of ultrasound is available. Also you will be able to find out how this or that type of diagnostics is carried out.
To begin with it is necessary to tell, what is this diagnostics. During the study, a special sensor is used which is connected to the equipment. The device sends sound waves through the human tissue. They can not be heard by a simple ear. The sound is reflected from the tissues and internal organs, and the specialist, because of this process, sees the image on the screen. It is worth noting that this contact occurs very quickly. The image of the area under investigation appears immediately after the sensor is applied to the body.
Types of ultrasound diagnosis
Ultrasound examination can be different. Such diagnostics are divided into types. It is worth noting that in each individual case a special sensor is used. They can be two or more on an ultrasound machine. So, ultrasound diagnosis can be as follows:

In most cases, the diagnosis is carried out inlying position. At the same time the couch should be firm, and in the office it is necessary to create a semi-dark effect. An exception may be duplex scanning and ultrasound of the kidneys. These examinations can be carried out in the vertical position of the patient.
