Reviews and News on Ultrasound Machines

Medical imaging or ultrasound machine technology has progressed in numerous ways over the years. Ultrasound machine capabilities and functions are more widely used in the medical field today and provide more effective diagnostic treatment than in the past. Ultrasound machine technology uses echoes and high frequency sound waves to create imagery. The industry has advanced by providing expedience, convenience, better image quality, and enhanced memory capacity. Also, portable or hand-carried ultrasound machines offer more mobility and easy to operate systems have allowed less experienced medical providers to provide quality care. It is important to note that ultrasound machines have reduced overall healthcare costs since they have replaced more costly diagnostic exams.

Years ago, ultrasound machines were utilized primarily in the fields of gynecology and obstetrics. Doctors and other medical professionals used the technology to observe and monitor prenatal conditions such as fetal size, position, gender, and growth rate. Recently, gynecologists have discovered that ultrasound machines are valuable tools for the detection of breast cancer. In addition to gynecology and obstetrics, ultrasound machines are effectively being used in other medical fields to detect abnormalities and for cancer screening.

Here are some other uses for ultrasound machine technology in the medical field:

* Emergency room workers are using ultrasound machines as a diagnostic tool in the ER.
* Cardiologists are using ultrasound machines to provide an image of the heart that can identify function abnormalities and measure blood flow.
* Urologists are able to use ultrasound machine technology to detect kidney stones and prostate cancer.
* In addition, ultrasound machines have recently been used in conjunction with rectum and colon exams and for treating chronic tendonitis.

Ultrasound machine technology is significantly beneficial to the medical community since it can be utilized without radiation and it can diagnose problems quicker than x-rays

It was only a matter of time before ultrasound machines joined the vast array of medical devices that can be worn around the neck or carried around in a pocket. An extraordinarily small ultrasound made by Signostics has achieved the feat of being reduced to a lightweight eight ounces while still including all of the needed data converters, amplifiers, processing and circuits found in much larger models.

Other than our national obsession with gadgetry, there are several other factors driving this trend toward miniaturization.

* The medical equipment industry’s first “single IC” USB isolator was introduced in 2009, and it has significantly decreased the design time, size limitations and cost to create an isolated USB solution.
* Patients have demanded ways to monitor their own health without the need for frequent trips to the doctor’s office, especially since many doctors are already overbooked.
* Palm-sized ultrasound devices (like the Signos by Signostics) are capable of producing high-resolution imaging with a simple touch-screen display and the ability to store up to 10,000 images. The technology used here is reminiscent of a smart phone, both in size and ease of use.
* When doctors are moving from one room to the next, it is easy for them to carry a Signos around their neck like a stethoscope or keep it in their pocket until the next use.
* Unlike larger ultrasound machines, which use multiple transducers and a more complex circuitry, the pocket-sized Signos uses only one transducer, which is controlled by hand movements, to generate a high resolution image.

This miniaturized version of an ultrasound machine is so new that it’s still too early to tell how it will impact the use of large machines in a clinical setting, but it will certainly be an interesting trend to watch.

Ultrasound technologists, also known as “diagnostic medical sonographers” spend their days operating ultrasound machines. Using high frequency sound (so high that humans cannot hear it), ultrasound machines use sound waves to create two dimensional images of the internal organs of the body. It is also commonly used to take images of a fetus during pregnancy, and to make images of the heart, cardiovascular system and abdomen.

Besides becoming ultrasound technologists, a medical imaging technologist can also specialize in CT scans, MRI and X-ray technology.

As a career choice, the field of medical imaging marries the use of technical knowledge and state-of-the-art equipment, with the ability to interact well with patients. As the population ages, the demand for ultrasound technologists is growing. They are not only needed in hospitals, but also at doctor’s offices and other health care settings. The recent expansion of ambulatory care and outpatient centers has created a new demand for medical professionals who can operate ultrasound machines, and the U.S. Bureau of Labor Statistics expects this demand to grow another 18 percent by the year 2018.

As a prerequisite for a profession like this, it helps to be a person who enjoys working in a helpful role with people. This is because a technologist will be working directly with patients on a daily basis. Some hospitals offer non-degree training programs that typically last for two years and cost about $3,000 per year. According the Jackson Memorial School of Technological Radiology, a Florida-based ultrasound technologist can expect to earn about $47,000 right out of school.

Ultrasound imaging was developed using the same principles as sonar, a technology that is used to find ships at sea. The only difference is, medical ultrasound machines are able to measure the length of time it takes sound waves to bounce back from internal areas of the body. The net effect is a two dimensional image that identifies the distance, size and shape of objects within. These images allow doctors to diagnose abnormalities, detect tumors, examine tendon tears, and evaluate the eyes.

During the course of an ultrasound examination, the machine’s transducer is used to show the targeted organ and produce images to be studied. The transducer itself emits sound waves and then detects the returning echoes as it passes over the body part being examined. It does this by differentiating between the sounds that are made by various tissues, because they each respond differently to the transducer’s frequency. The resulting echoes are then analyzed by a computer within the ultrasound machine, and they are shown to the doctor as moving images of the area being examined

Ultrasound waves pass quite readily through soft tissues and fluids, which make ultrasound machines the preferred method of examining fluid-filled organs like the uterus, liver and gallbladder. However, since ultrasound waves are unable to penetrate through bones or gases, the use of ultrasound machines for these areas is limited. Still, ultrasound is commonly used to study most parts of the body in hospitals and clinical settings.
