Health care professionals use them to view the heart, blood vessels, kidneys, liver and other organs. During pregnancy, doctors use ultrasound tests to examine the fetus. Unlike x-rays, ultrasound does not involve exposure to radiation. During an ultrasound test, a special technician or doctor moves a device called a transducer over part of your body. The transducer sends out sound waves, which bounce off the tissues inside your body. The transducer also captures the waves that bounce back. Images are created from these sound waves.

Staging Staging Liver Cancer Physical Exam Blood Tests ... Liver Biopsy We are part of the West Penn Allegheny Health System Ultrasound Ultrasound uses sound waves, not x-rays, to generate images. A jelly-like substance is applied to the skin overlying your liver. Then a probe, called a transducer, is passed over the skin. The transducer sends out sound waves that pass through the body and are echoed back. The transducer receives the echoes and transmits them to a computer console which in turn interprets the echo data as internal organs and tissues. Because ultrasound is simple, inexpensive and noninvasive, it is often one of the first tests ordered during the staging process. Unfortunately, test results are highly dependent upon the sonographer , the quality of the scanner, and the overall build of the patient. As a result, ultrasound may not detect all tumors in all cases. Ultrasound may be performed in the physician's office or on an outpatient basis in a clinic. Most ultrasound tests take only a few minutes and results are obtained immediately. In patients with liver tumors, ultrasound is used to locate and measure the size of a tumor and to determine if it is solid or cystic. In addition, ultrasound is an important modality that is used at the time of surgery and is called intraoperative ultrasound. This examination should be performed on all patients who undergo a surgical procedure on the liver. It will identify all of the tumors within the liver and clarify the relationship to blood vessels in the liver. The probe is placed directly on the liver at the time of surgery. This test provides critical information that will influence the treatment strategy.

Seminars Page Therapeutic Ultrasound Team Team Leader: Dr Gail ter Haar Location: Royal Marsden, Sutton Section: Joint Department of Physics The therapeutic ultrasound team is doing research designed to improve our understanding of the basic science behind the technique of high intensity focused ultrasound (HIFU) for the treatment of cancers of the liver and kidney, and to develop a novel clinical device in which we implement our findings. We are also supporting clinical trials of the use of trans-rectal HIFU for the treatment of recurrent prostate cancer. The basic principle of HIFU is that a high power ultrasound beam is brought to a tight focus at a distance from its source and is used to rapidly heat tissue to temperatures which result in cell death. Only cells in the focus are killed, overlying and surrounding tissue is unharmed. If the source is outside the body, this represents a non-invasive treatment for tumours lying deep below the skin.

Doctors routinely use ultrasound about halfway through pregnancy to check that the baby is developing normally but may use it earlier to confirm or rule out a miscarriage. How the Ultrasound is Done: In early pregnancy, when most miscarriages occur, the ultrasound is likely to be transvaginal in order to get the best picture of the developing gestational sac and baby. In a transvaginal ultrasound, the technician or doctor will ask the woman to undress from the waist down and put on a medical gown. The technician will then insert a probe into the vagina to get an image of the uterus and fallopian tubes.

To confine the wave, focused transducers are used, where high and low frequencies are modulated to take advantage of the focusing capability of high frequencies with the power that can be induced by low frequncies*. An experimental setup that was developed to harness the enabling capabilities of ultrasound was constructed and modified to allow data acquisition with the assistance of Stacey Walker. Cavitation, heating, steaming, and atomization were the phenomena that have been investigated. * Frequency Modulated High Power Ultrasound (FMPUL), Patent No. 5,827,204
