It is a fact in psychoacoustics that children can hear some high-pitched sounds that older adults cannot hear, because in humans the upper limit pitch of hearing tends to become lower with age.

Login American Pregnancy Association Promoting Pregnancy Wellness home about mission statement strategic services ... Prenatal Testing Ultrasound: Sonogram Email Email An ultrasound exam is a procedure that uses high-frequency sound waves to scan a woman's abdomen and pelvic cavity, creating a picture (sonogram) of the baby and placenta. Although the terms ultrasound and sonogram are technically different, they are used interchangeably and reference the same exam. What types of ultrasound are there? There are basically seven different ultrasound exams, but the principle process is the same. The different types of procedures include: Transvaginal Scans: Specially designed probe transducers are used inside the vagina to generate sonogram images. Most often used during the early stages of pregnancy. Standard Ultrasound: Traditional ultrasound exam which uses a transducer over the abdomen to generate 2-D images of the developing fetus . Advanced Ultrasound: This exam is similar to the standard ultrasound, but the exam targets a suspected problem and uses more sophisticated equipment.

The development of therapeutic applications of ultrasounds has really accelerated over the past 15 years. This new treatment approach has now been recognized and its many advantages are appreciated. In particular, it is generally acknowledged that there are fewer side effects compared with other techniques. The combination of this technique with such techniques as imaging, diagnostic ultrasound and MRI in particular, enables many pathologies to be treated, including cancerous tumors. This development has been made possible by the considerable efforts undertaken in academic and technological research. The researchers and manufacturers active in this field form a growing community which is heard in particular at such international conferences as the ISTU conference, the IEEE International Ultrasonics Symposium, the Ultrasonics International conference, the AMUM workshop, etc...

Investigation of the Potential Bioeffects from Diagnostic Ultrasound Exposure in Rat Lungs Ultrasound-Assisted Thrombolysis for Stroke Therapy Immunofluorescent staining of mature porcine whole-blood clot. The clot is located to the left of each panel. Panels A and B are stained with goat-antihuman rt-PA with a secondary of donkey-anti-goat conjugated to FITC. Panels C and D are stained with mouse anti-plasminogen and donkey-anti-mouse conjugated to Rhodamine. Panels A and C are treated with rt-PA in plasma alone and panels B and D were treated with rt-PA in plasma and 120-kHz pulsed ultrasound. These data show that ultrasound treatment dramatically increased rt-PA penetration into the clot. more pictures Targeted Liposomes for Acoustic Cardiovascular Imaging Echogenic liposomes (ELIP) are being developed at UTHSC-Houston for use as targeted ultrasound contrast agents and drug carriers for ultrasound-triggered drug delivery. Physical and acoustical characterization of ELIP is under way in the UC Ultrasound Research Laboratory to determine the optimum acoustic parameters for diagnostic and therapeutic applications. The utility of ELIP for contrast depends on their stability in an acoustic field, whereas the use of ELIP for drug delivery requires the liberation of encapsulated gas and drug payload at the desired treatment site. Our long-term goals are to determine, quantitate, and characterize the stage, extent, and pathophysiologic development of atherosclerosis, allowing directed therapy to improve physiologic flow following clinical intervention.
