Ultrasound technology allows medical professionals to look inside a patient without resorting to surgery. A transmitter is used to send high frequency sound waves in the body; the waves bounce off the different tissues and organs and hence produce a unique pattern of echoes. A receiver attached, hears the returning echo pattern and it sends it to a computer translating the data into an image on a television screen. Ultrasound can differentiate subtle variations between soft and fluid-filled tissues and is very useful in providing diagnostic images of the abdomen.
Ultrazvuk abdomena identifies abnormalities in liver, pancreas, gallbladder, spleen and kidneys. It is also used to identify and see fetal development in pregnancy. Moreover, it is also used to help guide in procedures like needle biopsies. In this procedure a needle takes a small sample of tissue and then that sample is sent to a laboratory.
Ultrazvuk abdomena is non-ionizing radiation hence it has no known negative effects. It is often used in conjunction with other imaging techniques. Ultrasound, x-ray, and magnetic resonance imaging (MRI) takes body images using diverse technologies and every technique is quite helpful in determining mass properties resulting in more complete diagnosis.
Ultrasound procedure produces sound waves quite above the frequency of human hearing capability that is about 20 thousand hertz, or cycles per second. Medical ultrasound normally uses frequencies between one and 10 million hertz (1-10 MHz). Higher the frequency, the more detailed images but has a downside that they are also more readily absorbed so the waves cannot penetrate as deeply into the body. Ultrazvuk abdomena is generally performed at frequencies between 2-5 MHz.
Bowel gas often makes it difficult to see internal organs. If a loop of gas-filled bowel lies between the transducer and the organ being imaged, an artifact called shadowing is seen on the image which blocks the view of the organ. Patients are often asked to fast for eight hours prior to the examination which allows bowel gas to subside for optimal imaging. Usually the patient undresses for this procedure. The shirt is pulled up around the chest and towels are used to protect the clothing from the ultrasound gel. This gel is water based solvent and doesn’t damage clothing. After drying it looks like a white splotch that can be easily removed.
The organs imaged during an Ultrazvuk abdomena consist of pancreas which is located in the upper, middle region of the abdomen, liver – a large organ that lies in the right upper quadrant of the abdomen and its size is measured. The patient usually lies on their back during the imaging of the liver and pancreas. The gallbladder is located underneath the liver and should be imaged with the patient in two positions, either lying on back or on the left side thus allowing the Sonographer to differentiate between gallstones and polyps as gallstones will move within the gallbladder with the change in position. Regardless of the potential difficulties encountered, ultrasound is faster and less expensive than computed tomography scans (CT), its primary rival in abdominal imaging.

History of the name Gadget
The word “gadget” can be traced back to the 19th century. The word in this case used as a substitute for the name of a device that you no longer have to remember. In this case the word “gadget” back in the book written by Robert Brown’s “Spunyarn and Spindrift, A sailor boy’s log of a voyage out and home in a China tea-clipper. This is the first time the word appears on paper. Another story is that Gaget, Gauthier & Cie (the company behind the decorative technique in sheet metal for the Statue of Liberty in New York) a small scale model of the Statue of Liberty and released it to the named company (Gaget – Gadget). This was in 1886. However, this would contradict the story between whether the term was used in the vernacular.

The history of gadgets spans as far back as humanity itself – since hominids began creating tools to make their lives easier. Humans have always created devices and appliances with specific practical purposes that were initially thought of as novelties, due to unfamiliarity with and initial unwillingness to accept the technology. Today, industry has augmented the creation of new gadgets, while certain retailers, including Brookstone and Richard Thalheimer’s RichardSolo.com, specialize in popularizing them.
What famous inventors Benjamin Franklin, Thomas Edison, Alexander Graham Bell and Leonardo da Vinci, among others, had in common was foresight. They understood that a lifetime spent playing with what others viewed as toys and senseless gadgets would eventually result in indispensable technology. From just that small group, the groundwork for electricity, communications, film, and flight was laid because of their gadgets, which obviously possessed more value than novelty.
Perhaps one of the earliest, most well known gadgets created is the wheel, many millennia ago. Take a ride in your car and witness how truly revolutionary such a gadget became and how much we now rely on it for transportation. A more recent gadget, the Apple iPhone, appears to be the beginning stages of yet another gadget-turned-necessity that will reshape communications.
“The iPhone may someday be looked upon as the device that started a second revolution in computing. Desktop computing was the first revolution. Hand-held computing will someday be regarded as the second revolution, and the iPhone is the product that started it.”
-Richard Thalheimer, RichardSolo.com
All gadgets were not created equal. In fact most inventions are built on the newest technology. The world of gadgets is tiered; devices fall into one of four categories: mechanical, electronic, programmable, and application. Mechanical gadgets include the wheel, as well as later developments such as the pulley, the bicycle, the sail boat, the thermometer and the sort. Following the advent of electricity, gadgets were taken to a new level as inventors began to discover different uses for the newly harnessed energy. The television, radio and quartz watch are examples of electronic gadgets. After electricity, inventors toyed around with electronic information via microprocessor, beginning an age of programmable devices such as computers, and later, MP3 players and the iPhone. Application gadgets include iTunes, Microsoft Office and other computer applications that customize our experience with programmable devices.
Richard Thalheimer, the President and founder of online gadget vendor RichardSolo.com, and founder and former CEO of gadget giant The Sharper Image, understands, maybe better than anyone, that there’s much more to gadgets than novelty.
“Certainly most people enjoy the novelty of a gadget that introduces new convenience to their lifestyle. What they forget is that solving these everyday problems is not just entertainment, but some of these devices become functional necessities. In my personal life, I rely on my iPhone, my garage door opener, my nose hair trimmer, my electric toothbrush, and other gadgets that were once regarded as novel gadgets. ”
– Richard Thalheimer, RichardSolo.com
Both his former brainchild and his current venture sell quirky, useful and fun gadgets of all types, from mechanical to programmable and application. He has seen some devices, such as the Ionic Breeze air purifier, spur sensational and lasting trends based on a realization of utility value, while others collected dust on the shelves after their novelty wore out. Specialty stores like The Sharper Image and Richard Thalheimer’s RichardSolo.com serve a greater purpose: spread new ideas, and give credit to the Franklins and Edisons of the world.
