Ultrasound devices

Over the past decade, ultrasound technology has made significant progress and has been marketed in small advanced and portable models. Currently, with the advancement of science and technology, many diagnostic and treatment processes are performed under the interventional measures of imaging and especially ultrasound.

Nowadays, buying an ultrasound machine is the concern of many specialist doctors. Specialist and subspecialist doctors in various fields such as obstetrics and gynecology, peritonology, pain medicine, sports medicine, emergency medicine, special care, neurology, endocrinology, urology, lung, surgery, etc. usually use ultrasound devices for ease of diagnosis and performing They use therapeutic interventions.

Ultrasound devices can be used in general imaging. Ultrasound devices are used for diagnostic imaging in the patient's bed and medical care (point of care). In general, ultrasound devices in general applications are usually used to image abdominal viscera such as the liver, kidneys, and vessels (aorta, inferior vena cava, IVC).
Types of ultrasound devices

Ultrasound devices are divided into two types: stationary and portable. In terms of wave technology, this device is grouped into three types of ultrasound: three-dimensional, four-dimensional (three-dimensional image with movement in time) and Doppler ultrasound.

Different types of probes are used in different ultrasound methods. Trans-vaginal, Convex, Linear, Volume Convex and Phase Array probes are used in various methods of transvaginal ultrasound, conventional ultrasound, color ultrasound or color Doppler.
Ultrasound machine components

Ultrasound devices consist of two main parts: probe and monitor. The probe is a tool for generating ultrasound waves and sending and receiving them inside the patient's body. The probe is usually designed in the form of a microphone that is connected to the monitor by a wire. In fact, the probe sends ultrasound waves into the patient's body and receives the echo of these waves and sends them to the monitoring system and scanners. The received echoes are then converted by the computer system into recognizable images from which photos or videos can be made. The working principles of this device are similar to sonar devices in military and marine systems. Sono device includes the following parts:

    Probe or Sound
    angle (we have a computer and numbers that can be used to calculate and fix the camera at different points and measure it)
    Monitor: reflected images of sound waves can be seen in it.

Types of probes:

    Liner probe
    Endocavind or vaginal probe
    Pectoral probe

Today, the Pectoral_Liner probe is mostly used, which is used throughout pregnancy. Vaginal probe is especially used for early diagnosis in early pregnancy, for example:

In early pregnancy bleeding (for example, those who have a history of ab and EP or incomplete ab), but the gestational sac is in such a way that it cannot be seen from the abdominal prop, the vaginal prop is used one week earlier if there is a gestational sac. see it

    Vaginal probes are also used at the end of pregnancy: for example, to see the condition of the cesarean scar, whether it has healed well or not.
    Vaginal probe is used when we want to give an early diagnosis of malformations. For example: in anencephaly
    How the ultrasound machine works

    The imaging of this device is the imaging method of sonar systems. In this method, ultrasound waves are sent to the target and the echo (feedback) of the ultrasound waves is measured after returning. By measuring the echo waves, the distance, size, shape and stability of the target objects as well as their gender can be evaluated and drawn.

    In the medical industry, ultrasound is used to observe the fetus in the uterus, heart valves and walls, identify abnormalities of the liver, gall bladder, cysts and stones in the urinary tract and kidneys, venous vessels, etc. To put it better, in the medical industry, the ultrasound device is used to display changes in the appearance of tissues, organs, vessels, and internal masses. In ultrasound medical devices, the probe plays the role of transmitter and receiver of waves. When the probe is stretched over the skin (or in some cases inserted into the body), ultrasound waves are sent into the body.

    Ultrasound waves are reflected by internal tissues and fluids and where the density of the tissues is different or the tissue is placed next to the fluids. In simpler terms, the interface between two tissues, tissues and liquids or gases are considered to reflect ultrasound waves. After that, the probe receives the echo and records the amount of their changes and by sending it to the computer and the monitor system, this data is converted into an image. These images are constantly changing and can be displayed as photos or in real time. In the Doppler ultrasound system, the movement of blood cells causes a change in the tone of the echo sound waves. With this method, the doctor can check the path and speed of the blood cells moving in the blood vessels.
