Ultrasound Gene Delivery

Of course many medical uses are fetal examinations and detection of tumors or growths. Ultrasound was also used a lot for physical therapy by heating the injured area and creating an increased blood flow so that the injured area could heal faster. Medical uses are important and well known there are many non-medical uses that really make you think and might not believe. In the late 1950’s ultrasound was used for remote controls for television. The hand held box had a resonator rod on it that little hammer hit with a microphone on the television set. These worked very well and did not need any battery power source. Another benefit to these was that the ultrasonic waves were not likely to affect any other surrounding electronics unlike radio waves can. These stopped being popular when inferred systems started being used in the late

Ultrasound imaging has many uses in medicine, from confirming and dating a pregnancy to diagnosing certain conditions and guiding doctors through precise medical procedures

Dr. Fox is an emergency physician at UCI Medical Center, treating and diagnosing patients using an ultrasound. His scope of research involves looking at patients’ internal organs via ultrasound, which is much quicker and less harmful than using x-ray scans that are traditionally used in emergency departments. He is also a part of the American Institute of Ultrasound in Medicine (“Faculty and Staff”). Dr. Fox is also a director of instructional ultrasound and is the assistant dean at the UCI School of Medicine (“John Christian Fox”). He started an ultrasound rotation at the UCI School of Medicine, and with a grant given by SonoSite, Inc., the ultrasound curriculum is now embedded within the UCI School of Medicine curriculum (“Faculty and Staff”). He went to Tufts University School of Medicine, receiving his MD in 1997 (“John Christian Fox”). His main research focus is to try to incorporate ultrasound more into the emergency department, and tries to find revolutionary ways to utilize ultrasound, especially because it is very cost-efficient and images are seen real-time, unlike MRI scans or x-rays, which can emit harmful radiation or results take much longer to acquire. Eric Viquez is one of the Bio 199/EMRAP (Emergency Medicine Research Associates Program) students in Dr. Fox’s ultrasound lab. He is currently a 4th year undergraduate biological sciences major who is going to medical school in the fall; he shadows shifts with Dr. Fox and

Ultrasound relies on high frequency sounds to image the body and diagnose patients. Ultrasounds are therefore longitudinal waves which cause particles to oscillate back and forth and produce a series of compressions and rarefactions

The use of contrast agents in ultrasound carries many unanswered questions. Some of the questions that have risen are if using these agents are safe and if they are beneficial and provide useful feedback for diagnosis. Research has been done to see if using contrast agents leads to any adverse events (AEs) [1]. There have been studies done for both echocardiography and ultrasonography and how contrast agents effect them both. !

X-rays use electromagnet waves to produce images. Ultrasounds are longitudinal sound waves with extremely high frequencies. The below table examines some of the differences

Have you ever wondered where a marble or penny you swallowed went? Well read my paper and you'll find out a way to track it. For over 20 years ultrasound imaging has been used and has an excellent safety record. Ultrasounds use non-ionizing radiation, so it does not have the same risks as X-rays or other types of imaging systems that use ionizing radiation.

Ultrasound in modern-day medicine is continually advancing, whereby it is used for a wide range of specialized procedures. The use of diagnostic ultrasound is considered ‘safe’, as no significant deleterious effects are reported in literature, for patients and operators. Nevertheless it is fundamental that the benefits outweigh the risks for when a patient is having an ultrasound exam, and that all precautions are considered to minimize any harm (Nelson et al. 2009).

Ultrasound has been used in obstetrics for over fifty years and is generally regarded as being very safe for both mother and fetus. However, there is also some limited research to suggest that ultrasound – especially when combined with certain influencing factors – may in fact carry potential to harm the fetus. The character of these potential risks range from relatively harmless effects to those that could result in more serious negative outcomes. When considering the available data, the potential for these adverse effects seems very low, but the rapid advancement of ultrasound technology and protocol in recent decades makes it difficult to be sure of the true consequences. Although ultrasound is generally considered to be safe, there is not currently enough evidence to prove definitively that modern obstetric ultrasound does not carry potential risks to the fetus, and so this technology should be used prudently with efforts taken to minimize its potential risks.

In the year 1940, H Gohr and Th. Wedekind exhibited their paper revealing the possibility that an ultrasonic machine could be used as a diagnosis tool (“History”). They stated in their paper that using ultrasonography to diagnose a patient would be able to reveal tumors, abscesses, and such. Using ultrasonography, doctors would be able to treat their patients and would be able to remove the tumors inside of them before they became a problem. Unfortunately for them, however, they were unable to write any valid answers from the experiments that they had

Ultrasound has been used as a therapeutic modality for decades. Depending on the frequency and duration of the ultrasound there has been speculation of possible effects of healing of a wide variety of conditions. Some including fractures, tendinopathies and overall healing of tendon and muscular injuries. Therapeutic ultrasound is a deep penetrating agent that produces changes in tissue through either thermal or non-thermal mechanisms6. Ultrasound uses acoustical energy, depending on the frequency and wavelength of the energy ultrasound can be used for imagining, therapeutic deep tissue heating or tissue destruction6.

Sound waves ranging from one to five megahertz hit boundaries between tissue. The boundary may be soft tissue, or soft tissue and bone. Reflected waves are sensed by the probe and relayed to the ultrasound machine. The machine will calculate the distance between the probe and the boundaries found, such as an organ or tissue. The calculations are based on the time of each echo’s return using the speed of sound (1,540 ft. /s). This produces a two dimensional image on the ultrasound machine’s screen, displaying the intensities and the distances of the echoes. Using this information, doctors can then diagnose many medical issues while not using invasive surgery. (Odorico, Jon, Dr., UW-Madison Transplant Surgery, Personal interview. Tuesday Apr.

The ultrasound works that you place a transducer on the gelcovered skin, and soundwaves are emitted into the body. This soundwaves travel until they reach different types of tissues which reflect the sound back, for example, when the soundwave passes from fluid to bone, some of the soundwaves reflects ans bounce off the bone back to the tranducer. Each time the soundwaves pass through a different medium within the body, whether it be oran tissue, donr och other tussues in the body this process continues.

Ultrasound is nontoxic, noninvasive and does not use ionizing radiation. The ultrasound equipment has the potential to increase efficacy and early detection in diverse medical fields such as anesthesia delivery, cardiac surgery, sports medicine, and emergency medicine. An ultrasound is uniquely powerful in that it is the only imaging technology that can be transported to a patient or used where a patient might most urgently need it. The ultrasound can be utilized on the side of a road after a serious motor accident or in remote communities, as well as, traveling to reach a health center. When considered this massive scope of medical applications, along with the universal necessity for imaging equipment among the country and borough population in India. The evidence shows why India 's ultrasound market poses both a significant business and public health opportunity.

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave will be reflected back to the probe. While some waves may carry on further till they hit another object and then reflected back. The probe picks up these reflected sound waves and relays them to the machine. The distance and time from the probe,
