Can males or females determine the direction of sound better?
All frogs are able to hear (if they were deaf, they wouldn't be calling). Because frogs always have two eardrums (tympana) they are able to determine the direction. A special frog is Amolops tormotus, because it is able to produce and hear ultrasound.
What is an obscured pancreas by overlying bowel?
On an abdominal ultrasound scan, the machine can produce images of liquids and soft tissues pretty well, but hard tissues like bone and air pockets do not produce images. To have a pancreas be obscured by bowel gas means a loop of intestines had a pocket of gas in it that was between the probe and the pancreas, so the pancreas could not be evaluated by the ultrasound. There is no disease or pathology present, just the intestines getting in the way of the scan of the pancreas.
What is the use of ultrasound imaging to create a detailed visual image of the brain?
Neurosonography is a small, specialized section of ultrasound, frequently used in the NICU on premature babies. Images of the brain are able to be produced on premature and young babies due to the skull not being fully fused together yet, therefore allowing the ultrasound beam to reach the brain tissue. Neurosonography is also used before the baby is born, and still in the mother's womb. Once the skull has fused, transcranial ultrasound is still possible to an extent, through very small openings within and around the skull. This area of ultrasound is frequently used in high risk pediatric and specialty hospitals, such as St. Jude Children's research hospital. Using ultrasound on the brain of a fully fused skull is more challenging because an ultrasound beam cannot penetrate through bone. However, with skill and knowledge, it is possible to obtain brain images.
The Career of an Ultrasound Tech?
An ultrasound technician, also referred to as a medical sonographer, utilizes diagnostic medical imaging equipment to assist in the diagnosis of medical diseases or monitor conditions such as pregnancy. This branch of diagnostic medicine uses sound waves to generates images that can be used for assessment and diagnostic purposes for a variety of medical conditions. The equipment uses high-frequency sound waves directed to a persons body which them forms an image from the reflected sounds. The images can be made into still pictures or videos or can be transmitted through a computer to a radiologist or physician.Most people are aware of ultrasounds that are used to view a fetus in the womb, but ultrasounds are used for a number of other areas and organs of the body. An ultrasound tech may decide to specialize in one or more areas. For example, an ultrasound tech can specialize in gynecologic sonography or obstetric ultrasounds. Abdominal sonography, ophthalmic sonography and neurosonography are also areas that the ultrasound tech may specialize in.An ultrasound tech has a number of duties besides operating the ultrasound equipment. The ultrasound tech must be able to explain the ultrasound procedure to the patient and well as instruct the patient on how to move to obtain the ultrasound images. At times, the ultrasound technician may have to assist or turn patients, which requires some level of physical stamina. The ultrasound tech must have good decision skills to select the best images to present to the physician. The ultrasound tech is often involved in obtaining patient medical history and recording this information into a computer. The ultrasound tech usually works in a hospital, physician’s office or a diagnostic imaging center.Most ultrasound technicians attend either a two-year or four-year program from a college or university. Training can also be obtained in a hospital or vocational technical institution. Although currently no state requires an ultrasound license, some agencies such as the American Registry of Diagnostic Medical Sonographers provide competency certifications for ultrasound technicians.According to the Bureau of Labor Statistics, employment of ultrasound technicians is expected to grow by about 18 percent until 2018. The average hourly rate of an ultrasound technologist was between $22.18 and $30.91 or $45,496 to $65,255 as of September 17, 2010, according to PayScale.com.
Who hears ultrasound?
No one is able to hear ultrasound; the frequency of the sound used is far higher than the audible limit of any person or animal. A sonographer will conduct an ultrasound. Ultrasound in the same way that bats navigate - by listening to echos. ultrasound is reflected in propotion to the density of soft tissues. an ultrasound displays the results of these echos.

Can implantation be seen with a ultrasound?
It is not likely. The earliest an ultrasound can usually detect pregnancy is about 5 1/2 weeks. Although you may be able to see a little sac (with essentially nothing in it) a heart beat may not be able to be detected. This is nothing to worry about though. Implantation occurs at Week 2 of pregnancy so it is not likely that implantation would be able to be seen with an ultrasound.
