When someone hears the word “ultrasound”, they probably immediately think babies, pregnancy, and those fuzzy black and white computer screens displaying the picture of a developing fetus. Modern medicine has now gone much further than those often grainy flat images a mother used to see. Three dimensional and even 4-D imaging is possible, and not only in medical facilities, but in veterinary clinics. Only a few universities were using this technology in the 1970 and 1980s, but today, modern advancements and availability allows clinics to depend on this technology for all kinds of cases. (Epperley, 2012) So how does it work, and is it actually worth all the training and expense to purchase one of these machines? One will see that each clinic may have its own needs as its own budget for this equipment, but only being fully educated on the uses of this technology will help owners decide if a machine is right for them.
So what is ultrasound technology and how in the world does it work? The word “ultrasound” is actually the practice of using sound waves to produce an image called a sonogram. This works by the machine producing sound waves at a frequency higher than humans can hear, and sending them through a targeted area on the body. As these waves travel through the body, they hit objects such as organs, blood, and air, and bounce off of them. The more dense the surface of the object the stronger the waves will bounce, or echo back. A machine then converts these echoes into digital imaging, where a technician known as a sonographer, can view it on a computer screen in real time. For example, if gallstones are present in the gallbladder, sound waves passing through will echo off of these dense stones and they will show...

Diagnostic medical sonography is a profession where sonographers direct high-frequency sound waves into a patient’s body through the use of specific equipment to diagnose or monitor a patient’s medical condition. As described by the Bureau of Labor Statistics, this examination is referred to as an ultrasound, sonogram, or echocardiogram. The high-frequency sound waves emitted from the handheld device, called a transducer, bounce back creating an echo and therefore produce an image that can be viewed on the sonographers computer screen. This image provides the sonographer and physician with an internal image of the patient’s body that will be used in the diagnosis. The most familiar use of ultrasound is used in monitoring pregnancies and is provided by obstetric and gynecologic sonographers, who also provide imaging of the female reproductive system. Other types of sonography include; abdominal sonography, breast sonography, musculoskeletal sonography, neurosonography and cardiovascular sonography. Due to the vast nature of uses in sonography, most professionals study one field that they choose to specialize in. Diagnostic medical sonography is a rapidly growing field because of the increase in medical advances. The area of Cleveland, Ohio has continued to rise in the medical field with great strides, providing better career prospects with the availability of numerous employment positions.

Humanity has relied heavily on animals for millennia, for everything from food to transport, companionship and entertainment, and as such animal welfare is a topic that is hugely important to us as a society. My passion for the preservation of animal health coupled with my love of science has set me up perfectly for a career as a veterinary surgeon.
Ultrasound Technicians are very valuable in the world of health care. Also known as Diagnostic Medical Sonographer, an Ultrasound Technician uses special machines and equipment that operates on sound waves to determine or diagnose medical problems for patients. There are specializations within this field in which some individuals explore. For instance, areas of specialization includes but not limited to; pregnancy, heart health, gynecology, and abdominal sonography. Although each specializing branch has its own distinctive function, they all involve probing the body to facilitate doctors with diagnoses.
Being able to identify lumps, swelling, tissue damage, cysts, and the overwhelming news of the sex of a baby all have something in common, an ultrasound. Swelling of the spleen, kidney stones, blood clots, aneurysms, cancer and so much more can be identified through the works of an ultrasound’s imaging technique. Ultrasound involves many concepts, procedures, and careers. The amount of medical possibilities involved with ultrasounds is useful in major medical diagnostics. The field of ultrasounds and career opportunities are widely growing. As medical careers flourish, needs for technicians in many fields of medicine are increasing. Instead of a doctor choosing complex and risky surgery to find out problems within the body, they can now choose a safer path; the ultrasound path. Patient’s history and physical evaluation are building blocks to diagnostics but ultrasounds are much greater. They are powerful tools used to see beyond the skin into the depths of a person’s body. What ultrasounds are, what types there are, and what they are used for, and the education and careers available are the major themes found in research on the subject. Knowledge of ultrasound and its background may help one decide what career is best for them. Understanding the wide array of diagnostic tests and their uses are essential to figuring out what a career as a sonographer entails and the type of education that is needed. Because there are plenty of possibilities for specializing with different technologies, there is a wide variety of job opportunities in the medical imaging career. The call for ultrasound’s assistance opens new paths in future high-quality careers.
When owners take their pets to the clinic, they are understandably anxious about the results and outcome of the visit. While it’s the veterinarian's job to provide care for the animal, it’s also their job to put the owners at ease, reassuring them that their pet will indeed be fine. This communication is vital for building trust, as it lets the owner know what is happening to their animal and gives them confidence in believing that everything will be okay. What’s more, veterinarians that take the time to thoroughly explain procedures and instructions regarding petcare, are teaching pet owners how to better tend to their
Many wonder how do ultrasounds truly work. Ultrasounds are actually more complex than what they seem to be. First, the ultrasound machine transmits high-frequency sound pulses into your body using a probe, and then sound waves travel into your body and hit a boundary between tissues (Freudenrich, 2011). An example of this would be between fluid and soft tissue and soft tissue and bone. After that, some of the sound waves get reflected back to the probe, while some travel on further until they reach another boundary and get reflected, the reflected waves are then picked up by the probe and relayed to the machine. The machine calculates the distance from the probe to the tissue or organ using the speed of sound in tissue and the time of the each echo's return. Finally, the machine displays the distances and intensities of the echoes on the screen, forming a two dimensional image like the one shown below (Freudenrich, 2011).
The Society of Diagnostic Medical Sonography is one of the largest diagnostic organizations with well over 28,000 members. They work with students who want to be sonographers. Some benefits are that they will help promote,advance and educate you.
In general, ultrasound waves produced by an instrument called transducer are sent into a patient. Some of the waves are absorbed, but the other portion of these waves are reflected when tissue and organ boundaries are encountered. The echoes produced by the reflected waves are then picked up by the transducer and translated in a visible picture often referred to as ultrasound. In the paragraphs that follow, the physics of how the transducer functions, what the ultrasound waves do, and how the image is formed will be explained.
In the field of Radiologic Technology it is very imperative that one continues their education. The advantages in doing so include the fact that one is allowing for growth and development during their professional career and another is that one is learning new skills and keeping up with new equipment.
The medical field is always evolving and becoming something better and stronger. In the imaging world
One of the most important and delicate piece of equipment that a hospital could have is the X-rays and Ultrasound machinery(Krans). An X-ray is an imaging test that doctor used to view inside of somebody’s body without any incision being made. Although this might seem incredible X-rays are very delicate since they use certain types of light which could harm significantly human skin(Krans). Biomedical Engineers are engaged with the mission of providing new machinery more effective and less harmful. Sometimes this can be very hard to accomplish. Science is constantly evolving and new things are being discovered therefore more questions are being
In science we trust. The very fulcrum upon which veterinary medicine stands is constructed by seemingly endless discovery and scientific inquiry. As our profession advances, the health of man and animal has become so entwined that they are nigh inseparable; indeed, the primary aim of veterinary public health is to strive for the overall well-being of humanity through studying, monitoring, and treating animals. My passion for animal medicine developed at a far later stage than most aspiring veterinary students, which allowed me to acquire and evaluate relevant knowledge in a unique way. I started college in 2011, intending on entering an entirely different career, but through a diverse wealth of experiences, I realized that veterinary medicine
Making sure your pet gets regular checkup is severally important. However, just like you get nervous when you are about to have a checkup it is understandable to be unsure what is going to happen at the veterinary appointment as well. In this article you will learn a few different tips on how to pick out a clinic for your pet.
There are a multitude of ways that veterinarians contribute to society. Vets work with research, food safety, lab animals, exotic animals, large animals, small animals, and more. Research brings medical, potentially life saving break throughs. Food safety keeps humans and animals safe and healthy. Exotic animal vet’s help with conservation and education. Large animal vet’s keep the meat animals and product animals, such as sheep and their wool, healthy. What is most important to me that veterinarians bring to society is keeping the bond between man and animal strong. Sixty-eight percent of US households has at least one pet. Our pets are what we go home to every night, they are pieces of us that makes us smile on bad days. As a vet, I help
