Ultrasound imaging or sonography produces images of the inside of the body using high-frequency sound waves. These are real time images that show the structure and functioning of the organs. Depending on the goals of a particular test, the phenomena being invested and equipment available, the ultrasound image to be used can be of four different types- 2D, 3D, 4D and Doppler ultrasound.
The Doppler Effect is applied in sonography to provide imaging of blood vessels and flow within them. Reflected sound waves are used in a Doppler ultrasound to see how blood flows through a blood vessel. It helps doctors evaluate blood flow through major arteries and veins such as those of arms, legs and neck. It can show the blocked or reduced blood flow in the major arteries of the neck that could cause a stroke. It can also help in diagnosing deep vein thrombosis (blood clots in leg veins) which can cause pulmonary embolism (blocked blood flow to the lungs). Doppler ultrasound is also used to check the health of the fetus by looking at the blood flow in an unborn baby.
Process: During Doppler ultrasound, gel is applied on the targeted area of the body to allow the sound waves to pass through. A hand-held instrument, also known as transducer, is then passed lightly over the skin above the blood vessel. The instrument sends and receives sound waves that are amplified through a microphone. The movement of blood cells causes a change in pitch of the reflected sound waves which is known as the Doppler Effect. The information is processed by the computer to provide graphs or pictures representing the flow of blood.
The three basic types of Doppler ultrasound are:
“Bedside” or Continuous Wave Doppler: Change in pitch of the sound waves is used to evaluate the blood flow through the area that may be blocked or narrowed. It provides a quick estimate of the extent of blood vessel damage or disease.
Duplex Doppler: Standard ultrasound methods are used to produce a picture of a blood vessel and the surrounding organs. The Doppler sounds are converted into a graph to get information about the speed and direction of blood flow through the blood vessel.
Color Doppler: The Doppler sounds are converted into colors that are overlaid on the image of the blood vessel and that represent the speed and direction of blood vessel through the vessel. Power Doppler is a special type of color Doppler which is used to get some hard and impossible images.
The use of Doppler machines is a boon to the medical science. Many used doppler ultrasound for sale are available. There are a number of online shops that deal in ultrasound instruments and also provide demo ultrasound scanners for the ease of customers. They provide these devices at reasonable prices.
Ultrasound equipment need a huge amount for investment. Every practitioner wants to get the best value on their equipment that combines top performance with affordability. There is a huge industry that specializes in manufacturing medical equipment used by hospitals, clinics and private practices. Some suppliers of medical instruments also deal in pre-owned equipment that has been refurbished.
Using pre-owned ultrasound equipment offers some practical advantages. Some of them have been discussed below.
Price: The most obvious benefit of buying refurbished ultrasound instruments is the price. Simple market factors bring down the price on equipment when it tis used or not of the most recent model. Buying used or refurbished equipment can help in saving up to 70% from the operating costs. Used ultrasound machines can be purchased for much less than the new one and is ideal for a clinic that has been set in a low-income community and does not have enough funds.
Quality: Refurbishedultrasound instruments are thoroughly inspected. Old parts are reclaimed or completely changed. Companies manufacturing ultrasound equipment have entire departments that do refurbishing and repairs. The service contract and high quality technical support gives a repaired machine the same capacity and durability as a brand new machine. These instruments pass a rigorous quality control process that ensures the machine to run just as well as new equipment at a greatly reduced cost.

An ultrasound scan, also known as a sonograph, uses high frequency sound waves to create an image of some part of inside of the body such as the stomach, liver, heart tendons, muscles joints and blood vessels.
Ultrasound has different applications in the field of medical science. Let us take a look at some of these applications.
Heart Disease: For patients showing symptoms of illness, ultrasound can examine the heart and circulatory system and provide necessary information about their structure and function. It is used to check the heart and valve abnormalities and also helps in evaluating the efficiency of the heart in pumping blood to the rest of the body. This helps in the early detection of the heart diseases.
Gynecology: Ultrasound is used to detect a wide range of gynecological conditions. It is often used as a part of a standard pelvic exam to find out conditions like internal bleeding, pelvic inflammatory disease, abscesses and pelvic masses. Ultrasound is also helpful in addressing infertility issues and also to monitor and examine the reproductive system in the early stages of embryo development in the fertility process.
Pregnancy and Fetal Imaging: Using ultrasound, doctors can predict premature delivery by examining the size of the cervix. A complete fetal exam involves imaging the baby's head, heart, kidneys, spine and stomach etc. to check for any abnormalities. Fetal aging during breeding period to predict calving date can be more precise if fetal body parts are measured on the ultrasound screen. Ultrasound also helps in checking for the possibility of multiple births, unusual orientation, if the baby is positioned correctly and also for sex determination.
Abdominal and Therapeutic Applications: Abdominal ultrasound helps in examining the liver, gall bladder, adrenal glands, pancreas, kidneys and other parts of the stomach and intestines and helps in detecting diseases like appendicitis. The high-frequency sound waves are used to vibrate the body cells and are therefore used in pain relief, scar reduction and skin and muscle regeneration.

A portable ultrasound serves the same function as a simple static ultrasound instrument. It uses high frequency sound waves to create an image of parts inside the body. Also, it can help doctors determine the age of the fetus and look for internal problems like tumors and other abnormal growth.
Portable ultrasound instruments are about the size of a large laptop computer. They have a screen and a medical keyboard for viewing and navigating the picture. Most of the devices operate on batteries, so users do not need a source of power to use it.
These machines were first used by the gynecologists and obstetricians that led to the visible decrease in the infant mortality rate. Portable ultrasound machines are considered a must for doctors visiting backward areas where they have little or no medical facilities with them. The machine does not hinder mobility as it can be taken along with an ease and convenience. Other than gynecology, these instruments are also now used for the vascular, endocrinology, cardiac and even pediatric diseases.
Portable ultrasound instruments are used to cure the most common types of pain, like muscle pains and inflammation. It works by creating sound waves that pass through the skin and affects the targeted area, may it be muscle or a joint. The pain is released without the need for medication or surgery. These machines can also increase the efficacy of certain pain medications (phonophoresis) by way of using sound waves.
Immediate and advanced treatment can be given to patients who may have heart disease. This technology allows a doctor to look for abnormalities and other heart related problems. It is also used for early detection of prostate cancer and any other disease that may exist along with it, so that treatment may begin immediately.
Portable ultrasound machines acquire and transmit data almost instantaneously. Performing an ultrasound with this device takes no longer than 10 minutes. These devices allow simple effective ultrasound examinations performed at the point of care, in turn speeding up decision making by the clinician.
There are many companies, you can find on online that specialize in manufacturing portable and hand-held ultrasound instruments. These portals also provide color Doppler ultrasound devices, used ultrasound equipment and a wide variety of world-known brands at reasonable prices. Many portable ultrasound device for sale are available.
Ultrasound uses sound waves to stimulate the tissues beneath the skin. These sound waves travel at an extremely high frequency between 800,000Hz and 2,000,000Hz which is undetectable by human ear. These waves cause physical stimulation of the molecules that enhances cell repair.
Ultrasound is used for numerous purposes in the field of medicine where abdominal ultrasound is most widely used.
Abdominal ultrasounds use a transducer probe with a wider footprint to produce images of large structures and areas of tissue. After gel is applied, the probe is used directly on the abdomen. It is preferred in any case because it is relatively safe and non-invasive.
This type of ultrasound is primarily used to predict premature delivery by examining the size of the cervix. Also, it is used to measure the blood flow to a fetus’s brain, heart, and other extremities such as the approximate gestational age. Abdominal ultrasound is also helpful in checking the possibility of multiple births and unusual orientation.
Abdominal ultrasound is used in acute as well as chronic abdominal pain. All the major organs like the liver, gall bladder, adrenal glands, pancreas and kidneys can be examined for signs of disease that appear as changes in size, shape, or internal structure. They are also very useful in case of an abdominal trauma. After a serious injury, internal bleeding from injured abdominal organs is the most serious threat. Ultrasound is used to pinpoint the location, cause, and severity of the injury.
Abdominal growths such as tumors, cysts, abscesses and scar tissues can be located and identified with ultrasound. It is useful in detecting liver diseases where jaundice tends to be a general symptom. Ultrasound can differentiate between many types and causes of liver malfunction and is also good at identifying obstruction of the bile ducts and cirrhosis.
Pancreatic diseases like inflammation of the pancreas and pancreatic stones, which can disrupt proper functioning, can also be detected using abdominal ultrasound. Gallstones can cause painful inflammation of the gall bladder. These can be readily identified with ultrasound.
Ultrasound equipment of various types preferred for different applications can be purchased from online shopping portals at reasonable rates. Many abdominal ultrasound for sale at low cost are available.
3D ultrasound is a medical ultrasound technique used to produce still pictures of the baby in three dimensions. A 3D ultrasound uses high-frequency sound waves and special imaging software to provide very clear pictures of the baby. This type of ultrasound can be done at any point in pregnancy. The 3D technology is easily available nowadays and give women a gleam of hope when they their child inside their womb.
The ultrasound scanner sends sound waves through the body which bounce back to the scanner and produce an image on the computer screen. A gel is applied before placing and moving the transducer over the skin.
There are many benefits offered by 3D ultrasounds. Let us take a look at some of these.
Better for Health Providers: A significant advantage of using this technology is that it allows the doctor to better assess an abnormality as compared to a 2D scan. In obstetric ultrasound, this technology helps doctor diagnose inborn abnormalities of a fetus. Other birth defects can also be seen with the equipment but the quality of the picture depends on the skill of the sonographer.
Better for the Parents: 3D ultrasound technology can be very encouraging for both the parents as they become excited after seeing their baby in the womb.
Better for Unwed Mothers: As this technology provides images of the baby growing inside the womb, it may dissuade an unwed mother from having an abortion.
The technology of 3D ultrasound has greatly helped doctors improve the way of check up on the health of the developing baby.

The arteries and veins within the body carry the blood from one part of the body to another. Nutrients and other important elements necessary for the survival of the body are carried by the blood. It is therefore important for the blood vessels to remain open and allow quick flow of the blood. Vascular assessment is done by the doctors to evaluate the efficiency of the blood vessels. Vascular ultrasound is the best technology that can be used for such a practice.
Vascular ultrasound is a non-invasive procedure that uses sound waves to examine the blood vessels to discover the areas of dilatation, narrowing or blockage. The vessels of the neck, arms and legs, including both the arteries and veins, are examined most frequently. This type of ultrasound provides images of the body's veins and arteries. It may also involve a Doppler ultrasound study to evaluate blood flowing through a blood vessel.
Here are some of the common uses of vascular ultrasound:
To perform a vascular ultrasound procedure, a clear gel is applied on the targeted area that helps the transducer make secure contact with the body. It is made sure that there are no air packets between the transducer and the skin as they may block the sound waves from passing into the body. The transducer is then placed and moved over the skin in various locations. The sound waves strike the targeted areas and then bounce back producing images on the computer screen. Doppler ultrasound is performed using the same transducer.
If you are thinking of buying ultrasound equipment for your clinic, it is better to purchase online. There are a number of online shopping stores that specialize in selling high-quality and branded ultrasound equipment at reasonable prices. Also, you can buy used ultrasound equipment if you are not planning to invest much.
