What is an ultrasound machine and what is it used for?

Advancements in medical technology have revolutionized the way health professionals diagnose and treat patients. One of these advancements is the ultrasound machine, a fundamental tool in various medical specialties. In this article, we will explore what an ultrasound machine is and how it is used in fields such as physiotherapy and gynecology. We will also discuss the Doppler ultrasound machine and the different types of ultrasound machines available in the market.

What is an ultrasound machine?

An ultrasound machine, also known as ultrasound, is a medical device that uses high-frequency sound waves to create real-time images of the body's internal tissues. These images, known as ultrasounds or sonograms, allow doctors to visualize organs, blood vessels, muscles, and other tissues in a non-invasive way.

With ultrasounds, the doctor can diagnose pathologies and anomalies. Therefore, it is a widely used instrument, especially in specialties such as physiotherapy, cardiology, urology, or gynecology. Currently, this technique is starting to be used in Primary Care.

To correctly perform an ultrasound, it is necessary to have previously received specific training.

How do ultrasound machines work?

Its operation is based on the principle of ultrasound. It emits ultrasounds that bounce off the body's internal structures and return to the ultrasound machine's transducer. From the information obtained, the equipment creates real-time images that doctors use to assess the state of tissues and diagnose various pathologies, as well as review organ formation. Abdominal ultrasound is the most common, and it explores the liver, kidneys, pancreas, spleen, and gallbladder. It is not a painful or invasive procedure and usually lasts about 10 minutes.

In recent years, this type of instrument has evolved significantly, achieving 3D, 4D, or even 5D ultrasounds.

Uses of the ultrasound machine

Use of the ultrasound machine in physiotherapy

The ultrasound machine has become a fundamental tool in this field. Physiotherapists use ultrasounds to evaluate injuries in soft tissues, muscles, tendons, and ligaments. This technology allows them to precisely visualize injuries and develop personalized and effective treatments that help speed up patients' recovery. It is a widely used technique, for example, in the professional sports field.

Gynecological ultrasound

In the field of gynecology, the ultrasound machine plays an important role. Thanks to them, internal reproductive organs, such as the uterus and ovaries, can be precisely visualized. These ultrasounds are essential for pregnancy monitoring, ovarian cysts, and gynecological pathologies.

Types of ultrasound machines

There are different types, each for specific applications:

Doppler Ultrasound Machines

It is a specialized variant that, by combining the use of ultrasounds and Doppler, measures the speed and direction of blood flow. Therefore, it is widely used in cardiology and obstetrics to evaluate blood flow in the fetus or the heart. It allows early detection of cardiovascular problems and monitoring of fetal development during pregnancy. It also serves to quantify the diameter of vessels, the presence of plaques, the detection of inflammatory lesions, circulation in the extremities, etc.

It is a non-invasive, safe, and effective test that is very useful for the early diagnosis of diseases.

Portable Ultrasound Machines

They are commonly used for general diagnostics, as they enable precision in the detection in the early stages of diseases. One of their most frequent applications is abdominal ultrasound.

Portable Doppler Ultrasound Machines with wifi

They are designed with the latest Wireless technology. This allows it to be used in emergency situations without the need for cables or internet for its operation.

It is very simple and intuitive to use, being able to connect to any mobile, tablet, or computer via wifi. The user can customize its use by changing a multitude of parameters.

Ultrasound Machine with linear probe

It is a portable Doppler system with a state-of-the-art LED screen and image definition that allows an optimized view. It manages to combine advanced performance with high image quality.

2D Ultrasound Machine

Creates two-dimensional images that are ideal for observing anatomy and its structure.

3D / 4D / 5D Ultrasound Machine

These ultrasound machines generate three-dimensional images in real-time, which provides a more detailed and realistic result. It is widely used in obstetrics to view the fetus. The resulting image allows its modification in color, light focus, and textures.

The 5D ultrasound is capable of more defined and realistic reconstruction of the fetus. The detection of fetal malformations can reach 85% under the best conditions. The 5D offers the highest guarantees. It is advisable to do the ultrasound between weeks 26 to 30 of pregnancy.

Frequently asked questions about ultrasound machines

What is the difference between an ultrasound machine and an x-ray?

Unlike x-rays, which use ionizing radiation, ultrasound machines use high-frequency sound waves to create real-time images of the body's internal tissues. This makes them a safe application during pregnancy.

Can ultrasound machines detect any type of muscle injury?

Although they are very effective in visualizing injuries in muscles, tendons, and ligaments, their detection ability can depend on various factors, such as their location and type of injury.

Is it safe to undergo ultrasounds during pregnancy?

Yes, in fact, ultrasounds are generally used in obstetrics for monitoring fetal development.

When is a Doppler ultrasound machine recommended in cardiac care?

It is commonly used in patients with heart conditions, such as diseases of the carotid arteries or valvular diseases, to evaluate blood flow. The healthcare professional decides what type of ultrasound is most appropriate based on the symptoms and medical history of the patient to be treated.

What is the difference between a 3D ultrasound and a 4D one?

The main difference between a 3D ultrasound machine and a 4D one is the time factor. While 3D creates static three-dimensional images, 4D adds the dimension of time, which allows to see in real-time the movement of internal structures, such as the developing fetus. This is very useful for obtaining moving images during pregnancy.

What are the differences between a 4D ultrasound and a 5D one?

While 4D ultrasound provides movement of the fetus, in real-time and in color, 5D ultrasound implements a volumetric image treatment that offers better texture, realism, sharpness, and final quality.
