An ultrasound is a diagnostic tool that uses high-frequency sound waves to construct images of the inside of the body, according to MedlinePlus. The sound waves bounce off of the internal organs and structures. A computer uses those reflected sound waves to create the picture.
Pregnancy centers, such as HOPE Pregnancy Center in Philadelphia, offer free limited obstetrical ultrasounds. OptionLine helps users locate pregnancy centers and services in towns and cities across the United States.
An ultrasound machine works by transmitting high-frequency soundwaves into the body and detecting waves that get reflected back to the probe after the sound hits dense tissue, according to Craig Freudenrich, Ph.D., of HowStuffWorks. After the probe, called a transducer, receives the reflected soundw
Probing questions provide a deeper understanding of an issue or topic. This type of question encourages reflection, aids in the creation of a paradigm shift and allows for multiple responses.
Examples of probing questions are: "What happened next?" "What would you do differently next time?" "How did you feel about that?" "What was your actual role in that?" "Why did you choose that method?" Probing questions are open-ended questions that are asked to gain in-depth information.
One basic technique for reading ultrasound entails correlating shades of black, white and gray with fluid, bone and tissue respectively. Cartilaginous material and low- or high-density organic matter will appear as gradations of these colors.
According to the American Pregnancy Association, the purpose of a 7-week ultrasound is to confirm viable pregnancy, confirm heartbeat, measure the crown-rump length or gestational age, confirm molar or ectopic pregnancy, and assess abnormal gestation. During the early stages of pregnancy, a transvag
During the 13th week ultrasound, the fetus's eyes are distinguishable, and its ankles and wrists are formed, according to WebMD. The baby's head still looks disproportionately large compared to the rest of the body but is typically more proportionate than in previous scans.
Ultrasound measurements are fetal measurements used by health care professionals to determine the gestational age of a fetus during pregnancy. Measurements that fall outside the normal range can indicate potential problems with the pregnancy.
A mother-to-be should get her first ultrasound during the midpoint of her pregnancy, around 18 and 20 weeks. Waiting until this time frame enables her to learn the child's sex.
