Ultrasound Equipment
Medical equipment - used ultrasound machines
Ultrasound machines are used to image internal organs through the use of ultrasound. It is a basic and accurate diagnostic method that allows doctors to conduct a non-invasive examination of internal organs, tissues and all structures inside the body and make decisions about treatment or preventive measures. Ultrasound machines emit high-frequency acoustic waves into the area to be examined, but these waves are not audible to humans. The examination is painless, while the penetration of ultrasound waves does not damage the body's cells. Therefore, an ultrasound examination, unlike an X-ray, is completely safe.
An ultrasound machine consists of two basic elements: an emitter and a receiver of the ultrasound wave. The emitter is responsible for sending out waves of a specific frequency. Waves in the 2- to 50-MHz range are sent toward the object under examination, propagate and encounter the object. They are then reflected and returned to the receiver. In medical devices, the wave speed is considered as a constant value and is 1540 m/s. Therefore, the instrument has the ability to accurately determine the distance to the limit of wave reflection. Based on the length of the sent and returning ultrasound waves, the ultrasound machine processes the data and creates an internal image of the examined area.
The ultrasound results obtained are accurate and provide adequate data for the physician to make diagnostic decisions. Since, in addition, the examination using acoustic waves is completely harmless, ultrasound is used in a variety of medical fields.
Most often, ultrasound is associated with the field of gynaecology. The use of an ultrasound machine head with a transvaginal probe allows for accurate imaging of the structures of the reproductive system in women in order to control and diagnose pathological changes in the uterus and other organs. In addition, the use of ultrasound equipment to monitor fetal development is common. Ultrasound examination is a standard method of monitoring the course of pregnancy, allowing to determine the condition of the fetus and its sex.
Ultrasound equipment is also used to diagnose diseases of the digestive system. It allows an initial examination of the internal organs without the need for invasive gastroscopy. Only after detecting abnormalities in the ultrasound image, the patient is referred for a more detailed examination of the diagnosed part of the digestive system.
In addition, ultrasound machines are used to image other organs and systems. Endocrine glands and blood vessels are often subject to ultrasound examination. Doppler-enhanced transducers are used to examine blood vessels, which allows the thickness of blood vessels to be assessed, the patency of even the smallest arteries and veins to be checked and the blood flow rate to be determined. Various ultrasound transducers are used to image different organs. The choice of the appropriate transducer depends on the place of application and the way the organs are examined.
Therefore, due to the widespread use of ultrasound machines, these devices are desired in all medical facilities. Buying used, working medical equipment allows you to equip a hospital or clinic well within a certain budget.
