High Intensity Focused Ultrasound Medical Physics

During my research of the High, intensity focused ultrasound (HIFU) for Prostate Cancer treatment. I found these facts and information on the topic of the HIFU treatment:

The use of High Intensity Focused Ultrasound for the treatment of prostate cancer is considered experimental and/or

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.

Ultrasound has become a diagnostic tool used in medicine over the past 40 years. This new imaging tool has helped patients and physicians. It has become commonplace in the medical community to order diagnostic ultrasounds for various conditions including pregnancy, cardiac disease and gastrointestinal diseases. Medicine continues to see many new advances for ultrasound.

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.

In diagnostic ultrasound examinations, very high frequency (1 to 5 megahertz) sound waves are directed at the body’s internal structures from a probe placed in contact with the skin (Ultrasound scan,

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.

An Ultrasound is an exam that uses high frequency waves to examine a pregnant women’s abdominal and pelvic cavity. The examination creates an on-screen picture (Sonogram) of the baby and the placenta. Ultrasounds and Sonograms are different but reference the same thing in the examination. There are seven different types of Ultrasounds/Sonograms, but the process is very similar within each one. The seven different ones are; Transvaginal scans, Standard Ultrasounds, Advanced Ultrasounds, Doppler Ultrasounds, 3-D Ultrasounds, 4-D or Dynamic 3-D Ultrasounds and Fetal Echocardiography.

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.

Did you know that ultrasounds were first used to detect problems in ships? Now they are used to help unborn and expecting mothers. Imagine seeing your daughter or son on a screen, as you await their birth to come. The Journey of life is amazing both in and out of the womb. Throughout the years technology has changed in so many ways. Now we give birth in a hospital and have technology to help us through the process. When 100 years ago, women gave birth in their own home. Ultrasounds now help expecting mothers more than ever and technology help your unborn child, throughout the whole process. Even ultrasounds have been improved, and technology has improved in the nursery. As technology changes so do we,lets see how it's changed in just the past

The 1960s introduced the use Ultrasound to the medical field. Since the introduction of Ultrasound there has been many technological advancements that have greatly improved ultrasound imaging and quality of diagnosis results. These

One promising new technology related to engineering is ultrasound probes which are used in Veterinarian Medicine also considered as a part of Biomedical Engineering. Taking biomedical engineering is a major required to take in order to learn the basics of this career path in college. Veterinarians use instruments to see what is wrong with their patient or in this case their animal. An example of one instrument veterinarian’s use most often that might need to be advanced, is an ultrasound probe. Which is used to view the inside of an animal and detect where the source of the problem is located.

The main principle of ultra sound imaging system is to transmit ultra sound burst signals into the particular organ and produced echo is processed for imaging.
