High Intensity Focused Ultrasound ( Hifu ) Therapy System, Electrical Impedance Matching Networks

In order to optimize the power delivered to the load to increase the efficiency of the secondary circuit, Rs must be diminished to as low of a value as possible. Likewise, in order to optimize the amount of power being delivered to the secondary circuit through coupling, the primary circuit must increase the amount of power from the source, as well as decrease the resistance in the primary coil itself. The quality factor of the secondary coil is inversely related to the secondary resistance, Rs. The system described is shown in Figure

Moving larger within basketball's game is one thing that many players execute on consistently. It only would seem sensible when-you're trying to score on the ten-foot holder the better the more odds can bounce you have of getting a larger participant and carrying out more concerns around the courtroom.

ultrasound system uses the high-frequency sound waves to produce images which are soft tissue and internal body organs.

Physical therapist clinicians select, prescribe, and implement use of physical agents for a number of therapeutically beneficial reasons.1 According to Cameron,2 physical agents are defined as energy or materials physically applied to patients to assist in rehabilitation. They include heat, cold, water, pressure, sound, electromagnetic radiation, and electrical currents. This study will focus on the use of therapeutic ultrasound (US) to treat osteoarthritis (OA) of the knee. Therapeutic US is regularly used passively by physical therapist clinicians3 to treat knee OA, but its use lacks substantial evidence of positive therapeutic effect in people with knee OA.4-6

High-Intensity Focused Ultrasound, HIFU, is rapidly becoming a growing prostate treatment. Because the area affected by the prostate cancer is targeted, the temperature can heat up quickly, which burns and destroys the cancer cells.

HIFU stands for high intensity focused ultrasound. Process includes high intensity sound waves to heat and destroy cancer cells. A pro of the treatment is that it is a less ivasive treatment compared to other cancer treatments. Also that you usually get to go home the same day as the procedure. Some cons of the HIFU are some men experience problems with urination which sometimes leads to bladder infections. Another con listed is that sometimes with this procedure some men expierence difficulty releasing semen during an orgasim. This complication could result in the patient not having children. I feel that this treatment should be approved to use because it actually not as harsh as many of the other cancer treatments, also it has less side effects.

The medical ultra sound field is always continuously expanding and making medical progress, and new findings. Ultrasounds are becoming more and more popular everyday. People are coming up with many new ways to help treat patients, and also new procedures to get better, and more defined images of the body. Also, people are making it possible to find some problems quicker than they ever could have before. A diagnostic medical sonographer is a professional, which has had the proper schooling to use technology to help diagnose patients. Sonographers use a special type of machine with a wand that takes images of the inside of your body. This wand is called a transducer. A transducer is the device that uses sound waves to capture images of the

There have been many technological advancements in the health care field. Ultrasounds have played a major role in these advancements. Many people have heard of an ultrasound or even undergone an exam themselves. Medical ultrasound imaging uses high-frequency sound waves to produce images of the inner body. Ultrasounds give health care professionals a visual of tissues. Sonographers are the skilled medical technicians trained to conduct ultrasounds. “A technician (sonographer) trained in ultrasound imaging will spread a clear, warm gel on the skin of the abdomen” (Shannon 205). Next the sonographer will rub the transducer over the gel. (Shannon 205). “The transducer converts electrical pulses into mechanical (sound) waves that are transmitted

Ultrasound is high frequency sound waves above 20,000 Hz. Often used to assist in medical diagnosis. Ultrasound waves are transmitted through the body where they are reflected off barriers, such as tissue or bone, providing a picture of what lies beneath the skin. (Freudenrich, Ph.D. Craig. "How Ultrasound Works." HowStuffWorks Science. HowStuffWorks, 22 Jan. 2001.)

Ultrasounds can work because they're made from sound waves. The sound waves produce an image. Sound waves go through your skin and focus on a certain part of your your body. There’s a scanning device that helps you focus on the body part, its called a “Transducer”. A transducer is a hand held small device that sends and receives signals from ultrasounds. A transducer changes impulses into sound waves.

The ExAblate 2000 (Insighte, Haifa, Isreal) focused ultrasound is used to ablate the kidney perfusion model. The result will state the effect of blood flow on FUS therapy. The parameters for MRgFUS in this experiment are as follows: TE=100ms, TR=150ms, Flip Angle=60°, Slice Thickness=5mm. Acoustic Power=20W, Duration Time=20s. The sonication target position were selected nearby main vessels, approximately 5mm away from the vessesl. Each selected position were sonicated twice, one under the conidtion with blood flow, while the other without. The overall flow speed is controlled at 500 mL/min for porcine kidneys and 200 mL/min for human kidneys. The temperature rises are

Ultrasound therapy generates high frequency waves that deliver vibrations into tissues. A special ultrasound gel is positioned on the skin to amplify contact, preventing to overheat, and providing the wand to glide through skin smoothly. The ultrasound therapy treatment wand is traveled throughout the surface of the skin. The wand transmits energy for three to five minutes around the zone of injury. The therapy can be treated twice daily depending if the patient has been diagnosed with acute pain or chronic pain.

The application of ultrasound to insert peripheral intravenous catheters (PIVs) has been clinical practicing in medical field for years. It becomes a highly precise technique that is required a fundamental knowledge as well as hand skill technical sets. Besides demonstrating the benefits of using ultrasound for PIVs insertion attemps, the following study will also provide a clear guidance for the technician.

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,
