This article describes how ultrasound technology works and the development and benefits of portable ultrasound scanners. It includes details on how examinations are performed and the key considerations to bear in mind prior to purchasing the required equipment.

Ultrasound technology is a non-invasive and painless way of analyzing and capturing the inner workings of the body and its internal organs. A sensor is covered in a viscous gel which passes over the area in question to examine inside the body. The sensation may be uncomfortable, especially when passed over any areas of discomfort, and the cold gel may cause momentary discomfort. However, the benefits of ultrasound examinations and scans can be realized in a variety of diagnostic settings, both for human patients as well as animals.

The scanner moves over the body and the moving images and sounds can be observed on a monitor and can provide vital information on muscles, internal organs and ligaments. Ultrasounds are carried out by sonographers who are trained and experienced in analyzing and performing diagnoses from these fuzzy images. Ultrasounds are offered as a routine part of a pregnant woman's care and are used as a tool for determining the age, birth weight and sex of a fetus, as well as provide key information on the health of the baby and any fetal growth abnormalities. Ultrasound technology is used for other procedures including biopsies, ECGs (echocardiography) and other important internal medical examinations.

The traditional ultrasound machines found in hospitals are large, heavy and difficult to move around, so the development of portable ultrasound scanners for sale is a welcome advance. Whereas these larger machines are designed for hospital use, these smaller portable ultrasound scanners for sale are ideal for patients who find it difficult to get to a hospital for diagnosis and treatment, and they offer an in-house diagnosis tool for vets too.

These smaller handheld devices are lighter and battery operated, and since their introduction has proved even more efficient in their design and application. There are many ways to find these portable ultrasound scanners for sale. Online platforms sell for personal purchase and individual use, as well as for health centers and doctors' surgeries. Popular with GPs, these scanners enable images and data to be stored via disc or on a card and forwarded to a specialist if required. Some have storage facilities of up to 8GB for storing larger images.

When deciding which scanner to purchase, ensure that the machine chosen is truly portable and light weight and can be carried for out of surgery visits easy. If the machine being purchased is a used item, ensure the manufacturer and website is authentic and that there is sufficient warranty left for the duration of the scanner's lifespan. Although these handheld scanners are smaller than machines found in hospitals, the portable option is still an investment and value for money needs to be guaranteed. Make sure there is a viable returns policy in place and guarantee that if the machine stops working within the warranty period, it can be returned without additional charge. The final consideration should be the purpose of the scanner: will it be used for human or animal analysis, as the size, radius and storage requirements will obviously differ.
