New Point-of-Care Ultrasound Equates to Exciting Careers

Ultrasound equipment technology is rapidly advancing, producing new devices that generate more accurate images. One of the newest developments was the introduction of hand-held ultrasound machines to be used at the point-of-care for patients. The streamlined equipment started new discussions on the role of ultrasound imaging in the transforming healthcare landscape. It is clear that ultrasound … [Read more...]

Sonography Imaging in Disease Analysis

Not so long ago the mention of “ultrasound imaging” usually first brought to mind fascinating pictures of fetuses still in the womb. The people who understood the greater abilities of sonography imaging were usually studying Diagnostic Medical Sonography or working as sonographers. Over the last decade, ultrasound technology has become increasingly sophisticated, leading researchers pursue new … [Read more...]

High Intensity Focused Ultrasound, its Effect on Medicine

High Intensity Focused Ultrasound and Patient

High intensity focused ultrasound is a non-invasive procedure that is similar to focusing the sun on a leaf with a magnifying glass. While the process is not intended to boil an organ, more physicians are seeking out this method to heat up and denature the affected tissues. The procedure can, theoretically, be performed inside an MRI and be closely monitored as an MRI measures the rise and fall of … [Read more...]

The History of Ultrasound

Ultrasund History

If you want to know the history of ultrasound, this is the right place for you. The earliest notions of ultrasound were developed in the late 19th and early 20th centuries in Europe. In particular, the French government during World War I assigned physicist Paul Langevin the task of creating a device capable of detecting underwater enemy submarines using high-frequency sonar. Over the next few … [Read more...]

What is an Ultrasound?

What is an Ultrasound

What is an Ultrasound? Those interested in sonography will benefit from knowing in greater detail how ultrasound works. The term itself refers to sound wave frequencies that are beyond 20,000 hertz, which is considered the upper limit of hearing in humans. Medical sonography is the transmission of high-frequency sound waves into the body and the conversion of the resulting reflections or echoes … [Read more...]

How Does an Ultrasound Machine Work?

Parts of Ultrasound Machines and Workflow

An ultrasound scanner consists of a number of components including a transducer probe, a central processing unit (CPU), a monitor, a keyboard with control knobs, disk storage devices, a printer and so on. The most essential component is the transducer probe. This probe both produces the sound waves used in ultrasound and receives their echoes back. It does so by taking advantage of a scientific … [Read more...]

4 Types of Ultrasound Imaging

Ultrasound Technician Imaging

The twelve major types of ultrasound procedures described in other articles, make use of four kinds of available ultrasound image. The choice of which type of image to use depends on the goals for a particular test, the phenomena being investigated and what equipment is available. 2D Ultrasound The most common and type of ultrasound picture is a series of flat, two-dimensional cross section … [Read more...]

Risks, Benefits and Future of Ultrasound

Ultrasound Benefits Risks Future

Although this website focuses on sonography as a career, another recurring theme was the many benefits of ultrasound procedure itself – benefits that will cause a high demand for sonographers both now and in future. Benefits of Ultrasound as a Diagnostic Tool Compared with other diagnostic tools, ultrasound is considered safe and produces no side effects. It does not expose patients to ionizing … [Read more...]

Abdominal Ultrasound Uses

Abdominal Ultrasound

This section with 12 short articles offers a systematic survey of the uses and limits of common types of ultrasound scans. In some cases, it builds on information presented earlier in the article 10 Types of Ultrasound Specialists to give a more complete picture of the capabilities of this powerful diagnostic tool as well as those contexts in which it has drawbacks or limitations. Abdominal … [Read more...]

Vascular Ultrasound Uses

Vascular Ultrasound is used to evaluate the veins, arteries and blood flow of the body. Vascular sonographers employ ultrasound to detect plaque accumulation, blood clots, embolisms, blockages and similar problems. Vascular sonography can detect deep venous thrombosis, which is the presence of blood clots in major arm or leg veins. It allows doctors to determine if patients are good candidates for … [Read more...]
