What is ultrasound transducer?
In general, a transducer is a device for changing one form of energy into another. There are lots of things that qualify as transducers under that definition. Just to cite a few examples, a microphone converts the mechanical energy of sound into electrical energy. A speaker does the opposite. An acoustic hydrophone converts the mechanical energy of sound in water or another fluid into electrical energy. In an example of how a transducer works, in ultrasound investigating technology, an electrical signal is used to create mechanical energy in the transducer, thus creating an outgoing pulse. Then the returning mechanical energy, the echo, is converted into electrical energy by the same transducer. The electrical signal is then used in imaging what the transducer is "looking at" by creating a picture of some sort which will then be evaluated. In another way, it could be said that a transducer is a device for sensing and relaying a signal, but keep in mind the idea of a change of "form" of the energy. That's what a transducer does is make the change. A transducer might be used to detect level, pressure, temperature, flow, displacement, accelaration, velocity, etc., from the sensing location so it can be sent to another place (like a control room). It consists of different parts like sensing element (the sensor), signal conditioning unit (filtering, amplification, etc.) and in some cases protocol interface (in order to convert the measured value into a digital frame for example). The latter transducer falls into Smart Transducer category. Links to relevant posts can be found below.
52 weeks + 1 day in a common year
52 weeks + 2 days in a leap year
This is the reason why a certain date (in most cases), will be one weekday later the following year, if a year was exactly 52 weeks (364 days) long, every date will land on the same weekday each year.
How do you tell a mouse's gender?
Male and female mice can be differentiated by observing the distance from the anus and genital papilla, which is greater in males. Differentiation is usually easier in adult mice.
How do you find out how far along you are if you think you are 4 weeks pregnant?
you work out the date of the first day of period and count how many weeks its been since then, that's how far you will be or use a due date calculator.
The easiest place is on the side of the neck, in the place where the jaw and neck muscles form a V.
Tripple Marker Test is only for down's syndrome, where as TIFFA scan is used to check for all anomalies.
TIFFA is the acronoym for "Targeted Imaging for. Fetal Anomalies". It covers a wide area compared to Tripple marker which is only for down's syndrome.
In short, Yes TIFFA scan is required and there is no guarantee that TIFFA should be normal when Tripple Marker is normal.
What modern technology helps scientist compare orginisms and assign them groups?
four modern classification system
Yup! I calculate conception to be between the 10th and 13th of September! Congrats!
Does a female need to be naked to have her heartbeat listened to?
She does not have to be naked. Part of her chest must be exposed in order to place the stereoscope next to her heart, but, the rest of her body can be covered up.
As long as the baby is healthy.
What are the benefits of ultrasound assisted liposuction?
As the name implies ultrasound assisted liposuction is a less invasive procedure to remove fatty areas without having to make a large incision. This hastens recovery time for the patient.
Who has heard of Kaplan College wondering about their reputation?
Each of the individual schools is separately accredited by one of several national or regional accrediting agencies approved by the U.S. Department of Education.
WARNING!!
When choosing any college or university, make sure the institution has a regional accreditation (most important). With a regional accreditation, you can be sure the course work and degree you complete will be recognized by all other accredited colleges ans universities, as well as employers.
Not all of Kaplan's campuses have the appropriate accreditation. I would be very careful before pursuing a degree at this institution. There are just too many excellent schools out there to limit yourself to one that is questionable. In addition, many of these great schools offer on-line degrees if on-campus course work is a problem because of time constraints.
Severely spranged my ancle on Saturday, Shut my hand in the truck door (all the way) on Thursday, and broke two fingers. Nope, Not this week. Thanks for asking.
Answer: Not medically as long as it's not viable. After that it has rights as you and me. Then people have their own opinions based on their feelings.
Answer: Since some believe life starts at conception, they do, in fact, consider a fetus an "unborn child", regardless of what a fetus is considered medically.
Before 12 weeks the uterus normally sits too low to be felt protruding over the pubic bone.
Starting at 12 weeks, the top of the fundus is first felt at the top of the pubic bone, from 12 weeks on - a normal growth will be about 1 cm per week gestation, from the top of the pubic bone to the top of the fundus.
At 14 weeks the fundus will be 2cm (+12) past the pubic bone, for a total measurement of 14 cm so at 27 weeks, the measurement from the mothers' pubic bone to the top of the fundus should measure 15 cm (+12) for a total of 27 cm.
A fundus/uterus measuring large for dates may indicate your due date is off, a multiple pregnancy (twins), your baby is positioned high above your pelvis, which might be the case with a breech baby, or an abnormally high amount of amniotic fluid causing the uterus to be larger than expected.
if your uterus is growing more rapidly than it should. You may also have unusual abdominal discomfort, increased back pain, shortness of breath, and swelling in your feet and ankles. If you have these symptoms, your midwife should send you for an ultrasound.
At 27 weeks your baby is between 14.5"/36 cm - head to toe and weighs 2 lbs /875 gm.
At 35 weeks your baby will be about 18"/47 cm and will weigh 5.5lbs /2.7Kg
A difference of 8 cm (8 weeks!) is too much to leave to chance, you need to get an explanation from your midwife on "large for dates" or decide if you could have miscalculated your LMP. Otherwise you may want to talk to your midwife about getting an ultrasound to determine why there is such a difference.
if you are not confident in the numbers your midwife is using you should see an Obstetrician and again request an ultrasound to determine if there is a miscalculation or if there is something going on...
What is the cost of a renal ultrasound test?
it's very expensive , last time I had it done for kidney stone it was 1100 dollars for hospital and Dr charged me $800 at Northwestern .Chicago
Is an empty gestational sac common at 5 weeks?
I thought they couldn't see any thing until 6 weeks. You might want to wait before you start stressing. At 5 weeks an ultrasound tech. can see a thickening in the uterine lining but a heartbeat cannot be detected because the embryo is not developed enough. It might appear empty to you because there is nothing there but a spec the size of maybe the point on a pen, if that big!So I would not worry.
After how many weeks do you start to show?
I started showing at about 16 weeks. Which between 16 and 20 weeks is average.
Why do we use high frequency waves as carrier waves?
The use of high frequencies for carrier waves in communications permits a higher rate of information transfer than could be accomplished with lower frequencies. The higher frequencies have the potential for higher "data density" or "information density" than lower frequencies.
What does the passing of a fetal sac look like?
when i had my first miscarriage the fetal sac came out in the toilet and it looked like a little veiny blood sac. it was really small almost like a bubble.
