There is as yet no comprehensive, multidisciplinary assessment of ultrasound use during pregnancy, including: clinical effectiveness, psychosocial effects, ethical considerations, legal implications, cost benefit, and safety. Williams, chater, allen, sherwood, and sanderson (1978) investigated the effect of ultrasound on platelets and established that more î²-thromboglobulin, a platelet specific protein, was released by ultrasound therapy. The bio-effects of invasive applications of lf ultrasound are not relevant to this review because of the high intensities used 1 this paper is concerned with the interaction, hazards and safety of low frequency (20-100 khz), low. Essay about career in ultrasound 2033 words | 9 pages overwhelming news of the sex of a baby all have something in common, an ultrasound swelling of the spleen, kidney stones, blood clots, aneurysms, cancer and so much more can be identified through the works of an ultrasound's imaging technique.
Ultrasounds (us) refer to mechanical vibrations, which are essentially the same as sound waves but of a higher frequency us is a deep penetrating modality capable of producing changes in tissue through both. ultrasound an ultrasound is a medical imaging technique uses high frequency sound waves to look inside the body during world war 2, there was a lot of research of radar and sonar which led to the invention and progress of the ultrasound device.
The effects repeats itself over various tissues with changing from one tissue interphases to another, and the consequently changes the properties of an ultrasound wave known as acoustic properties (baker, 2007 robertson, 2001. In terms of medical ultrasound, the doppler effect is a change in frequency of the received echoes (compared to the frequencies of the transmission pulse), due to the target moving relative to the front face of the transducer.
Drug and alcohol effects on the fetus the time that the fetus is in the womb is one of the most crucial times in development it is during this time that the fetus is easily susceptible to catching anything that the mother consumes or is exposed to. Thermal effects of ultrasound ultrasound is capable of producing thermal therapeutic effects 2 in 1987, dyson 1 suggested that the tissue must reach a temperature of 40°c to 45°c for at least 5 minutes to be therapeutic in nature. Ultrasound physical effects of ultrasound: 1- thermal effects 2- non-thermal effects 3- effect of us in tissue repair first: thermal effect @ it is due to generation of heat within the tissue due to adsorption of us @ tissue with high amount of protein absorbs us more than other tissues. 3d and 4d fetal ultrasound advances spark research, create challenges may 01, 2013 advances in 3d and 4d ultrasound technology now offer capabilities ranging from better visualization of congenital birth defects to dynamic, multiplanar views of the fetal heart.
Particular concern has been raised about the effects of doppler ultrasound on an unborn baby because doppler uses continuous waves rather than intermittent pulses and thus causes greater exposure when compared with conventional ultrasound potentially more dangerous is the increasing prevalence of so-called keepsake ultrasounds. The effects of ultrasound technology have been proven to have many effects on the fetal bodies in australia a study conducted on1400 pregnant women showed that women who had 5 monthly ultrasound tests, as compared to women who only had one throughout the entire pregnancy, gave birth lower weight babies over all. Negative effects of ultra sounds sounding the alarm on hazardous ultrasound - again it's been a year since i've written anything about this, but.
The effect of the ultrasound was found to be more short-term than long-term, suggesting more research be conducted on the long-term effects the follow up evaluation resulted in long lasting effects in the experimental group.

Are ultrasounds safe there's no evidence that scans are harmful, if used according to the guidelines ultrasound scans have been used in pregnancy for decades the person carrying out the scans (sonographer) will follow all the right guidelines to ensure that you and your baby are safe (scor/bmus 2015.
Transvaginal ultrasounds are used most often during early pregnancy, when the uterus and fallopian tubes are closer to the vagina than to the abdominal surface transabdominal ultrasound a transabdominal fetal ultrasound is done by moving a transducer — a small plastic device that sends and receives sound waves — over your abdomen. Risks of 3d/4d ultrasound although no obvious risks have been identified with 3d/4d scanning as is the case with 2d scanning, the american institute of ultrasound in medicine warns against the possibility of biological effects of scanning which may be identified in future (wood, 2008. Medical imaging admission essay ultrasound (also called sonography) is a diagnostic medical procedure cause and effect expository reflective definition. The levels set by the fda are not based on safety studies but on relative risk 4, 6, 14 there is essentially no evidence that prenatal ultrasounds do not damage the fetus 3, 7 researchers who have touched on the topic uniformly call for closer examination of the effects of ultrasound on the fetus 1, 2, 5, 18 of more concern is the high rate.
